Aim: To elaborate and validate an instrument for Brazilian Portuguese speakers, to assess dentists' knowledge about care of patients with diabetes mellitus (Dental-Diabetes). Methods: Methodological study comprising four stages: a) Elaboration of instrument; b) Content validation (computing Content Validity Index - CVI) based on Expert Committee assessment; c) Pre-test with 30 dentists, followed by assessment of suggestions by Expert Committee; d) Psychometric validation through instrument application in a sample of 127 dentists by means of the web tool e-Surv. Cronbach's alpha and intraclass correlation coefficients were used to evaluate, respectively, internal consistency and reproducibility. Results: The final version of the instrument consists of 22 questions (7 on sociodemographic data and 15 querying dentists' knowledge) and those submitted for validation attained a CVI of 0.95 [95% CI 0.916-0,981], showing satisfactory internal consistency, with 0.794 Cronbach's alpha [95% CI 0.741-0.842] and an intraclass correlation coefficient of 0.799 [95% CI: 0.746-0.846] between the test and retest scores. Conclusions: Dental-Diabetes is a comprehensive instrument, culturally adequate and validated to assess dentists' knowledge about care of patients with diabetes

Comparison of the reproducibility of two cervical vertebrae maturation methods

Aim: Facial orthopaedic treatments based on the stimulation or restrictions of craniofacial bone growth are more effective when carried out during the pubertal growth spurt. The aim of this cross-sectional study was to evaluate the reproducibility of two cervical vertebrae methods (CVM) with manual tracing and direct visual inspection. Methods: A sample of 60 lateral cephalometric radiographs (10 of each of the 6 CVM stages) was randomly selected from 171 records. 5 orthodontists classified these radiographs according to the skeletal maturation stage in 2002 and 2005, and the application of both methods was conducted by direct visual inspection and evaluation through manual tracing. Results: The average reliability of the two methods determination and the two forms of evaluation was substantial. The direct visual inspection evaluation showed the highest reliability and agreement interexaminer values for both methods, as well as the intraexaminers evaluation. Conclusion: The reproducibility of CVM method was substantial, indicating its clinical use to determine the skeletal maturity and the ideal moment for treatment execution

Introduction: Temporomandibular disorders (TMD) is a highly underreported health problem. In addition, its diagnosis is complex and requires the use of valid and reliable instruments for use in epidemiological studies. Objective: To validate the Epidemiological Diagnostic Instrument for TMD (EDI/TMD), with applicability for national epidemiological studies. Methodology: This is a validation study, internal structure validity through Exploratory Factor Analysis (EFA), reliability (internal consistency, interobserver and intraobserver), and convergent validity of the EDI/TMD were assessed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) as the gold standards. The sample was composed of 221 volunteers, 120 in the EFA stage, 50 for the test-retest, and 101 for convergent validity. Results: AFE showed three factors (Muscles TMD, Joint TMD, and Differential Diagnosis) with all items having factor loadings > 0.4, which explained 73.3% of the total variance. Good internal consistency with Cronbach's alpha= 0.775. Reliability ranged from substantial to excellent, reproducibility interobserver (Kappa=0.74-1.00, ICC=0.91-0.97; p< 0.001) and intraobserver (Kappa= 0.75-1.00, ICC=0.80-0.98; p< 0.001). The EDI/TMD total score showed valid and satisfactory diagnostic criteria according to the DC/TMD (Kappa= 0.906; p<0.001), with the ability to differentiate between individuals without and with TMD with a cut-off point of 4.9 (Sensitivity=1.0; Specificity=1.0; AUR=1.0); Mixed TMD with a cut-off point of 14 or more (Sensitivity=0.8; Specificity=1.0; AUR=0.987); and either Muscles TMD (Sensitivity=1.0; Specificity= 0.88; PPV= 0.89; NPV=1.0) or Joint TMD (Sensitivity=0.95; Specificity= 0.87; PPV= 0.83; NPV=0.96), with a cut-off point between 5-13.9, with the diagnosis obtained from the highest score in each factor (Muscles or Joint). Conclusion: The EDI/TMD is a valid and reliable assessment tool, with adequate and satisfactory psychometric properties, capable of diagnosing people with TMD and classifying the subtype of the condition (Muscles, Joint, and Mixed) (AU).

Reliability of a digital system for models measurements in BBO grading: A pilot study

ABSTRACT Introduction: Currently, no method is considered effective for the evaluation of digital models in the Certification Examination of the Brazilian Board of Orthodontics (BBO), considering the parameters of the currently used manual method. Objective: Thus, the aim of this study is to verify the reliability of an evaluation method for digital models that could be used in the BBO exam, compared to the gold standard. Methods: Measurements were performed by five previously calibrated examiners. Samples of ten sets of plaster models of the final phase of orthodontic treatment were measured using a manual method (Objective Grading System, OGS). These models were digitized using a 3D scanner and exported to Geomagic Qualify software, in which the measurements were made with the proposed digital method. These measurements were repeated using five models, after fifteen days. The intra-examiner performance with this method was analyzed with a paired t-test, whereas the inter-examiner analysis was carried out with analysis of variance and Tukey's test. To compare the manual and digital methods, a paired t-test and Pearson's correlation analysis were performed. Results: A statistically significant difference was found. The results showed that, when compared to the manual method, the digital method was effective in measuring the OGS in four of the seven variables studied: Marginal Ridge, Overjet, Occlusal Contact, and Interproximal Contact. The variables Alignment, BL inclination, and Occlusal Relationship showed a great amount of dispersion in the findings. Conclusion: Further studies are needed to develop an adequate digital methodology that can be used for all OGS variables.

RESUMO Introdução: Ainda não há um método considerado eficaz para análise dos modelos digitais no exame do Board Brasileiro de Ortodontia (BBO), considerando-se os parâmetros do método manual atual. Objetivo: Assim, o presente estudo objetiva verificar a confiabilidade de um método de avaliação em modelos digitais para o exame do BBO, comparando com o padrão-ouro. Métodos: As medições foram realizadas por 5 examinadores, previamente calibrados. A amostra de 10 pares de modelos de gesso da fase final do tratamento ortodôntico foi medida no método manual (Sistema Objetivo de Avaliação, SOA). Os modelos foram digitalizados por meio de um scanner 3D e exportados para o software Geomagic Qualify, onde foram feitas as medidas no método digital proposto. As medidas foram refeitas em 5 modelos após 15 dias. A análise intraexaminador desse método foi realizada por meio do teste t pareado; já a interexaminadores, feita com ANOVA e teste de Tukey, sendo encontrada diferença estatisticamente significativa. Para a comparação dos métodos manual e digital, foram utilizados o teste t pareado e a correlação de Pearson. Resultados: Uma diferença estatisticamente significativa foi encontrada. Os resultados mostraram que, comparada ao método manual, a metodologia digital mostrou-se eficaz para medição do SOA em quatro das sete variáveis estudadas: Margem interproximal, Sobressaliência, Contato oclusal e Contato interproximal. As variáveis Alinhamento, Inclinação V-L e Relação oclusal mostraram muita dispersão nos achados. Conclusão: Mais estudos são necessários para o desenvolvimento de uma metodologia digital adequada em todas as variáveis do SOA.

Theoretical report: reflections and considerations for authors, reviewers, and editors / Relato teórico: reflexões e considerações para autores, revisores e editores

ABSTRACT Epidemiological studies focused on public health have currently shown significant limitations regarding in-depth theoretical reports, overvaluing methodological aspects. The lack of theoretical explanation affects both the quality and reproducibility of studies. This study therefore reflected on the importance of in-depth theoretical reports considering the theoretical foundation used by researchers in the main sections of the manuscript (title, abstract, introduction, methodology, results, discussion, and conclusion) based on a review of the scientific literature on the subject. We believe that this article can help understand the importance and the development of in-depth theoretical reports in scientific articles, contributing to assessments, interpretations, and criticisms of reviewers and editors regarding the explanation and reporting of theoretical foundation in manuscripts submitted to scientific journals.

RESUMO Atualmente, os estudos epidemiológicos voltados à saúde pública têm apresentado limitações importantes quanto ao relato teórico em profundidade, frente a uma supervalorização de aspectos metodológicos. A falta de explicitação teórica nas publicações, afeta não apenas a qualidade do estudo, como também sua reprodutibilidade. Nesse sentido, apoiados em uma revisão da literatura científica acerca do tema, apresentamos neste ensaio reflexões sobre a importância do relato teórico aprofundado, relacionado à fundamentação teórica adotada por pesquisadores nas principais seções do manuscrito (título, resumo, introdução, metodologia, resultados, discussão e conclusão). Acreditamos que este artigo pode favorecer a compreensão sobre a importância e desenvolvimento de relatos teóricos aprofundados em artigos científicos e contribuir para avaliações, interpretações e críticas dos revisores e editores em relação à importância da explicitação e do relato da fundamentação teórica nos manuscritos submetidos aos periódicos científicos.

Novo método de sobreposição mandibular usando o programa Autodesk Inventor® para avaliação da acurácia do protocolo G8 da Invisalign® / New mandibular superposition method using Autodesk Inventor® software to evaluate the accuracy of the Invisalign® G8 protocol

O uso de alinhadores transparentes tem se tornado um fenômeno mundial na clínica ortodôntica e muitos esforços e recursos têm sido consumidos para que o resultado do tratamento seja o mais acurado possível. Em 2021 a Invisalgn® lançou protocolo G8 prometendo melhor previsibilidade no tratamento. É através da sobreposição de imagens que estes resultados podem ser avaliados. Na literatura, encontram-se relatos de diversos métodos e softwares que buscam confiabilidade para sobreposição de modelos tridimensionais (3D), entretanto não há consenso sobre estes métodos. Desta forma, os objetivos deste estudo foram: (1) Desenvolver novo método de sobreposição de modelos 3D com Autodesk Inventor®, (2) avaliar a reprodutibilidade do Autodesk Inventor® utilizando o sistema de coordenadas universais (UCS) associado a único ponto para sobreposição de modelos ortodônticos 3D da mandíbula e maxila, (3) avaliar a reprodutibilidade do Autodesk Inventor® na sobreposição de modelo ortodôntico 3D da maxila e mandíbula, (4) Comparar a acurácia do protocolo G8 através do resultado previsto pelo ClinCheck® com o resultado real obtido nos movimentos de intrusão e expansão dentária posterior. Para responder os objetivos 1, 2 e 3, foram selecionados 11 pares de modelos em STL (estereolitografia) de ambos os arcos exportados pelo software My Itero® e tratados com Invisalign® em dois tempos: início (T0) e refinamento (T1). As sobreposições foram realizadas utilizando os softwares Slicer® (versão 4.1) e Autodesk Inventor® usando como referência os planos dos 3 eixos cartesianos UCS (X, Y e Z) associado a um ponto na segunda ruga palatina na maxila e, na mandíbula, um ponto na linha muco gengival lingual. Após a sobreposição os movimentos de translação buco-lingual dos caninos, pré-molares e molares superiores e inferiores, intrusão, rotação dos caninos e incisivos mandibulares foram analisados por dois examinadores calibrados. Para responder o objetivo 4, a acurácia foi comparada nos movimentos alcançados e previstos pelo ClinCheck® entre três casos em que o protocolo G8 foi ativado e 8 casos em que não foi ativado para a expansão posterior maxila e mandíbula, intrusão de caninos e incisivos inferiores. Os resultados do objetivo 1, 2 e 3 foram coeficientes de correlação intraclasse (ICC) maior que 0,90 em todas as medidas, não foi observado erro sistemático avaliado pela fórmula de Dahlberg. Nos resultados do objetivo 4 não foram observadas diferenças estatísticas significativas entre os grupos. A acurácia no grupo G8 quando comparada ao grupo não G8 para expansão posterior na mandíbula e maxila aumentou 12.7% e 7,8% respectivamente, mas não houve diferenças estatísticas significante. Para o movimento de intrusão, a acurácia do grupo G8 foi 7,7% maior que a do grupo não G8 sem diferença estatística entre eles. Não foram observadas diferenças estatísticas significativas nos movimentos dos dentes dos grupos G8 e não G8. Concluiu-se que o método desenvolvido se mostrou reprodutível para sobreposição de modelos tridimensionais. O protocolo G8, quando ativado, não apresenta maior acurácia para o tratamento com Invisalign®.

The use of clear aligners has become a worldwide phenomenon in orthodontic practice and much effort and resources have been expended to ensure that the treatment outcome is as accurate as possible. In 2021 Invisalgn® released the G8 protocol promises better treatment predictability. It is through image superimposition that these results can be evaluated. In the literature, there are reports of various methods and software that seek reliability for superimposing three-dimensional (3D) models, but there is no consensus on these methods. Thus, the objectives of this study were: (1) Develop a new method for superimposing 3D models with Autodesk Inventor®, (2) evaluate the reproducibility of Autodesk Inventor® using the universal coordinate system (UCS) associated with a single point for superimposing 3D orthodontic models of the mandible and maxilla (3) Evaluate the reproducibility of Autodesk Inventor® in superimposing orthodontic 3D models of the maxilla and mandible, (4) Compare the accuracy of the G8 protocol through the result predicted by ClinCheck® with the actual result obtained in intrusion movements and posterior dental expansion. To answer the objectives 1, 2 and 3, 11 pairs of STL (Stereo- lithography) models of both arches exported by My Itero® software and treated with Invisalign® were selected at two times: initial (T0) and refinement (T1). The superpositions were performed using the Slicer® (version 4.1) and Autodesk Inventor® software using as reference the planes of the three Cartesian axes (X, Y and Z) associated with a point on the second palatal crease in the maxilla and, in the mandible, a point on the lingual mucous gingival line. After superimposition, the bucco-lingual translation movements of the canines, premolars and upper and lower molars, intrusion, rotation of the canines and mandibular incisors were analyzed by two calibrated examiners. To answer the objective 4, the accuracy was compared in the movements achieved and predicted by ClinCheck® between three cases in which the G8 protocol was activated and 8 cases in which it was not activated for maxillary and mandibular posterior expansion, canine and mandibular incisor intrusion. The results of objectives 1, 2 and 3 were intraclass correlation coefficients (ICC) greater than 0.90 in all measurements, no systematic error evaluated by the Dahlberg formula was observed. In the results of objective 4, no statistically significant differences were observed between the groups. The accuracy in the G8 group when compared to the non-G8 group for posterior expansion in the mandible and maxilla increased by 12.7% and 7.8% respectively but without statistically significant differences. For intrusion movement, the accuracy of the G8 group was 7.7% higher than the non G8 group with no statistical difference between groups. No statistically significant differences were observed in the tooth movements of the G8 and non-G8 groups. It was concluded that the developed method proved reproducible for three- dimensional model superimposition. The G8 protocol, when activated, does not present greater accuracy for treatment with Invisalign®

Modified short version of the oral health impact profile for patients undergoing orthodontic treatment

Aim: To derive and validate a short version of the Oral Health Impact Profile (OHIP) in Spanish to measure oral health quality of life (OHRQoL) for subjects wearing fixed orthodontic appliances. Methods: Cross-sectional study (data for sensitivity to change analysis were collected longitudinally). The data of 400 subjects (27.34 years, SD 11.66 years, 231 women, and 169 men) were used to develop a short-form instrument, and the data of 126 other subjects (25.95 years, SD 12.39 years, 62 women, and 64 men) were used for its validation. The original OHIPs were translated into Spanish using an iterative forward-backward sequence. After face and content validity were evaluated by an expert committee, an exploratory factorial analysis (EFA) was used to derive the Spanish short-form instrument (OHIP-S14 Ortho). To validate the OHIP-S14 Ortho, validity (content validity assessed by EFA, construct validity assessed by confirmatory factor analysis (CFA), discriminative validity assessed by the Kruskal-Wallis test, and reliability (internal consistency assessed by Cronbach's α test-retest, and inter-observer reliability assessed by correlation coefficients) were evaluated. Sensitivity to change and usefulness of the scale were also evaluated. Results: The OHIP-S14 Ortho included only six of the items in Slade´s original OHIP-14 short-form. A two-factor structure with adequate discriminative validity was found. High internal consistency (α=0.912), excellent inter-observer (Lin's correlation=0.97±0.011; rho= 0.97), test-retest agreement (Lin's correlation=0.80±0.059) and adequate sensitivity to change were also found. Conclusions: The OHIP-S14 Ortho is a valid and reliable instrument to measure OHRQoL in Spanish-speaking patients with fixed orthodontic appliances

Validation of the Brazilian Version of the RMS Tactile Scale (B-RMS-TS)

Abstract This study aimed to validate the Brazilian version of the RMS Tactile Scale (B-RMS-TS) in children and adolescents with visual impairment. Ten visually impaired children and adolescents between 10 and 17 years old of an Educational Center for Visually Impaired People answered the verbalized Dental Anxiety Scale (DAS), and the DAS in Braille to evaluate their dental anxiety levels. B-RMS-TS construct validity was assessed by convergent and discriminant validity. Convergent validity was tested in two ways: Pearson's correlation between the B-RMS-TS and the overall anxiety question; Pearson's correlation between B-RMS-TS and verbalized DAS and DAS in Braille. B-RMS-TS reliability was measured by internal consistency (Cronbach's alfa and McDonald's omega) and test-retest reliability (ICC). B-RMS-TS was moderately correlated to the overall anxiety question (r=0.493;p=0.147). B-RMS-TS showed excellent correlation with verbalized DAS (r=0.971;p<0.001) and DAS in Braille (r=0.934;p<0.011). B-RMS-TS was able to discriminate dental anxiety levels between male and female (p=0.008). The B-RMS-TS demonstrated excellent reliability (Cronbach's alpha=0.661, McDonald's omega=0.700 and ICC=0.987; 95%CI=0.817-0.999). B-RMS-TS is valid and reliable to measure dental anxiety levels in Brazilian children and adolescents with visual impairment.

Resumo Este estudo objetivou validar a versão brasileira da escala tátil RMS (B-RMS-TS) em crianças e adolescentes com deficiência visual. Dez crianças e adolescentes deficientes visuais entre 10 e 17 anos de idade de um Centro Educacional para Pessoas Deficientes Visuais responderam a Dental Anxiety Scale (DAS) verbalizada, e a DAS em Braille para avaliar seus níveis de ansiedade odontológica. A validade de construto da B-RMS-TS foi avaliada pela validade convergente e discriminante. A validade convergente foi testada em duas maneiras: correlação de Pearson entre a B-RMS-TS e a questão geral de ansiedade; correlação de Pearson entre a B-RMS-TS e a DAS verbalizada e a DAS em Braille. A confiabilidade da B-RMS-TS foi mensurada pela consistência interna (alfa de Cronbach e ômega de McDonald).) e confiabilidade teste-reteste (CCI). A B-RMS-TS foi correlacionada moderadamente à questão geral de ansiedade (r=0,493;p=0,147). A B-RMS-TS mostrou correlação excelente com a DAS verbalizada (r=0,971;p<0,001) e com a DAS em Braille (r=0,934;p<0,011). A B-RMS-TS foi capaz de discriminar níveis de ansiedade odontológica entre meninos e meninas (p=0,008). A B-RMS-TS demonstrou confiabilidade excelente (alfa de Cronbach=0,661, ômega de McDonald=0,700 e CCI=0,987; 95%IC=0,817-0,999). A B-RMS-TS é válida e confiável para mensurar níveis de ansiedade odontológica em crianças e adolescentes brasileiros com deficiência visual.

Escala de triagem odontológica para pacientes com necessidades especiais / Dental screening scale for patients with special needs

Objetivo: elaborar e testar uma Escala de Triagem Odontológica para Pacientes com Necessidades Especiais (PNEs). Métodos: a escala foi elaborada a partir da experiência clínica de um centro de referência para aten-dimento odontológico a PNEs e de evidências científicas. Foi construída utilizando cinco critérios principais: comportamento, necessidade e possibilidade de estabilização protetora, urgência odontológica (dor), núme-ro e complexidade de procedimentos odontológicos e local do atendimento (acessibilidade). O instrumento foi testado em 14 PNEs, que participaram de uma triagem no Centro de Especialidades Odontológicas (CEO) Jequitibá, na Faculdade de Odontologia da Universidade Federal de Pelotas (UFPel). Estudantes de gradua-ção a partir do oitavo semestre fizeram a aplicação, e o resultado da escala foi comparado ao parecer clínico realizado pelos pesquisadores experientes no atendimento a esses pacientes. Resultados: foi observada uma concordância em 85% dos casos. Conclusão: o instrumento apresentou desempenho comparável à avalia-ção de profissionais com expertise, e a escala pode ser um instrumento útil para ser empregado em serviços odontológicos que oferecem atendimento aos PNEs. A sua utilização em meio acadêmico também pode pro-porcionar o empoderamento dos critérios de avaliação pelos estudantes, proporcionando maior segurança em acolher, atender ou encaminhar esse público no seu futuro profissional.

Objective: to develop and test a dental screening scale to be used of patients with special needs (PSN). Method: the scale was developed based on the clinical experience of a reference center for dental care for PSN and scientific evidence. It was built using 5 main criteria: behavior, need and possibility of protective stabilization (PE), dental urgency (pain), number and complexity of dental procedures and place of care (accessibility). The instrument was tested on 14 PSN who participated in a screening at the Center for Dental Specialties (CEO) Jequitibá, Faculty of Dentistry, UFPEL. Undergraduate students from the eighth semester onwards applied and the result of the scale was compared to the clinical opinion carried out by experienced researchers in the care of these patients. Results: agreement was observed in 85% of cases. Conclusion: the instrument presented performance comparable to the evaluation of professionals with expertise and the scale can be a useful instrument to be used in dental services that offer care to PSN. Its use in academia can also provide the empowerment of assessment criteria by students, providing greater security in welcoming, serving or referring this audience in their professional future.

Validade da Escala de Imagens Faciais (FIS) para uso com crianças brasileiras na clínica odontopediátrica / Validity of the Facial Image Scale (FIS) for use with Brazilian children in the pediatric dental clinic

O objetivo deste estudo foi avaliar a validade da Escala de Imagens Faciais (Facial Image Scale; FIS) em pacientes odontopediátricos do Rio de Janeiro, Brasil, por meio da: 1) validade de critério concorrente, medida através do Venham Picture Test ­ versão brasileira; 2) validade de construto, medida através da correlação da FIS com as variáveis idade, sexo, ansiedade percebida pelos pais/cuidadores, classificação socioeconômica (renda), primeira visita ao dentista, tipo de tratamento realizado, uso de anestesia local, experiência prévia e atual de dor de dente, índice de cárie dentária e comportamento durante a consulta odontológica; 3) avaliação qualitativa com 30 crianças de forma a conhecer se o instrumento estava capturando o sentimento da criança em relação à ATO. A forma de aplicação da FIS foi adaptada para o contexto brasileiro por um grupo de quatro odontopediatras brasileiras e uma psicóloga britânica (autora da FIS). O trabalho foi aprovado pelo comitê de ética em pesquisa do Hospital Universitário Pedro Ernesto - HUPE/UERJ. Foram incluídas crianças de três a 12 anos de idade e seus responsáveis, que compareceram ao tratamento odontológico em clínicas de odontopediatria da Faculdade de Odontologia da Universidade do Estado do Rio de Janeiro, do serviço de Odontologia da Policlínica Piquet Carneiro e do Ambulatório Naval da Penha da Marinha do Brasil. Foram excluídas crianças com deficiências e que não quiseram participar do estudo. Foi realizado um estudo piloto com objetivo de avaliar a compreensão da FIS e testar os procedimentos que seriam empregados no estudo principal, em uma amostra não probabilística de 15 crianças/responsáveis. Os resultados sugeriram que a idade poderia influenciar na mensuração da validade da escala e foi decidido realizar um processo de amostragem por cotas, adaptações das instruções de aplicação da FIS e VPT para uma linguagem mais acessível e decisão de realizar o estudo qualitativo. A amostra selecionada por cotas do estudo de validação compreendeu 150 crianças, divididas em grupos de 31 crianças nas faixas etárias 3-4 anos, 5-6 anos, 7-8 anos, 9-10 anos e 26 crianças na faixa etária de 11-12 anos; 65 (43%) eram do sexo feminino; 20 (13,3%) estavam indo ao dentista pela primeira vez; 47 procedimentos invasivos foram realizados no dia da entrevista (tratamento restaurador, procedimentos sob isolamento absoluto, exodontia e/ou tratamento endodôntico); 55 (36,7%) não tiveram experiência de cárie na dentição decídua (ceod=0) e 111 (74%) na dentição permanente (CPOD=0). O coeficiente de correlação de Spearman (rs) com a Venham Picture Test foi moderado (rs= 0,50; p<0,01) e foram encontradas associações estatisticamente significativas (p <0,05) com sexo feminino, ansiedade percebida pelos cuidadores, uso de isolamento absoluto, dor de dente atual e experiência de cárie. O estudo qualitativo encontrou discrepâncias entre a escolha da FIS e o sentimento da criança em relação à ATO em todas as faixas etárias. Os resultados sugerem que a FIS não parece ser capaz de medir de forma válida a ATO em crianças brasileiras

This study aimed to evaluate the validity of the Facial Image Scale (FIS) in pediatric dental patients in Rio de Janeiro, Brazil, based on: 1) the criterion validity, which was measured with the Venham Picture Test - Brazilian version; 2) the construct validity, using the correlation of FIS with the following variables: age, sex, DA perceived by parents/caregivers, socioeconomic classification (income), first visit the dentist, type of treatment performed, use of local anesthesia, previous and current experience of toothache, dental caries index and behavior during the dental appointment; and 3) a qualitative assessment with 30 children to evaluate if the instrument was capturing the child's feeling regarding DA. The form of application of the FIS was adapted to the Brazilian context by a group of four Brazilian pediatric dentists and a British psychologist (author of the FIS). The work was approved by the research ethics committee of the Pedro Ernesto University Hospital ­ HUPE/UERJ. Children aged 3 to 12 years old and their guardians who attended a dental appointment in the pediatric dentistry clinics of the Faculty of Dentistry of the Rio de Janeiro State University, the dental service of the Policlínica Piquet Carneiro Polyclinic and Penha's Naval Ambulatory of the Brazilian Navy were included. Children with special needs and who did not want to participate in the study were excluded. A pilot study was carried out to assess the understanding of FIS and test the procedures that would be used in the main study, in a non-probabilistic sample of 15 children/guardians. The results suggested that age could influence the measurement of FIS validity and it was decided to carry out a sampling process by quotas, adaptations of the FIS and VPT application instructions for a more accessible language and decision to carry out the qualitative study. The sample selected by quotas of the validation study comprised 150 children, divided into groups of 31 children aged 3-4 years, 5-6 years, 7-8 years, 9-10 years, and 26 children aged 11-12 years; 65 (43%) were female; 20 (13.3%) had their first dental appointment; 47 invasive procedures were performed on the day of the interview (restorative treatment, procedures under rubber dam, extraction and/or endodontic treatment); 55 (36.7%) had no experience of caries in the primary dentition (dmft=0) and 111 (74%) in the permanent dentition (DMFT=0). Spearman's correlation coefficient (rs) with the Venham Picture Test was moderate (rs=0.50; p<0.01); statistically significant associations (p<0.05) was found with female gender, anxiety perceived by caregivers, use of rubber dam, current toothache, and caries experience. The qualitative study found discrepancies between the choice of FIS and the child's feelings towards DA in all age groups. The results suggest that FIS does not seem to be able to measure DA in Brazilian children.

Cross-cultural adaptation and psychometric properties of the short version of COPSOQ II-Brazil

ABSTRACT OBJECTIVES Translate and culturally adapt the short version of Copenhagen Psychosocial Questionnaire II (COPSOQ II) into Brazilian Portuguese (COPSOQ II-Br) and evaluate its psychometric properties. METHODS Translation and cultural adaptation followed the standardized guidelines. Structural validity was assessed using exploratory factorial analysis. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC3,1) and internal consistency by Cronbach's alpha. Floor and ceiling effect was considered acceptable if less than 15% of participants reported the lowest or highest scores. Measurement error was assessed by standard error of measurement (SEM), while construct validity was tested by correlating the COPSOQ II-Br, the Job Content Questionnaire and the Nordic Musculoskeletal Questionnaire. RESULTS The study evaluated a total of 211 civil servants and service providers in the test and 157 in the retest. After cross-cultural adaptation, the COPSOQ II-Br structure comprised seven domains and 11 dimensions. Most dimensions showed acceptable floor and ceiling effects, excepting "Work family conflicts" (floor effect of 26.1%), and "Meaning and commitment" and "Job satisfaction," with ceiling floor of 27.5% and 22.3%, respectively. Cronbach's alpha values reached the recommended levels (varied between 0.70 and 0.87). Test-retest reliability indicated that all dimensions had ICC between 0.71 and 0.81. SEM ranged from 0.6 to 2.2 and the construct validity showed good results with the tested instruments (significant positive and negative correlations). CONCLUSIONS All psychometric properties of the short version COPSOQ II-Br are suitable for use in Brazil. The instrument is thus validated and can be used by occupational health and human resources professionals to evaluate psychosocial working conditions.

Cross-cultural Adaptation of the Adverse Childhood Experiences International Questionnaire / Adaptação transcultural do Adverse Childhood Experiences International Questionnaire

ABSTRACT OBJECTIVE: To translate, adapt and validate the contents of the Adverse Childhood Experiences International Questionnaire to a Portuguese version, to be used in Brazil, named Questionário Internacional de Experiências Adversas na Infância. METHODS: This is a methodological study of cross-cultural adaptation of evaluation instruments presenting the results of semantic equivalence between the original instrument and the adapted version. The semantic equivalence of the instrument involved the following steps: 1) two translations and a synthesis of the translations; 2) two retranslations; 3) validation of contents by eight health workers; 4) synthesis of the retranslations; 5) pre-tests to assess acceptability, understanding and emotional impact of the questions; and, finally, 6) writing of the final version of the instrument. RESULTS: the adapted version proved to be easy to apply and to understand and achieved good semantic equivalence when compared to the original version. The psychometric properties of the instrument still need to be evaluated. Limitations and recommendations for improving the instrument and its use are presented. CONCLUSION: The process of cross-cultural adaptation of the Adverse Childhood Experiences International Questionnaire resulted in an adapted version to Brazilian Portuguese.

Pool of items to measure Primary Health Care workers' knowledge on healthy eating

ABSTRACT OBJECTIVE To develop and validate a self-applicable instrument for measuring primary health care (PHC) workers' knowledge on healthy eating. METHODS A six-step methodological study to develop and validate a measurement instrument: item development based on the Brazilian Dietary Guidelines' chapters; content validation with a panel of experts; face validation with potential instrument users; online instrument reevaluation by participants of the content and face validation panels; online application of the instrument with PHC workers; confirmatory factor analysis for construct validation. RESULTS A first version with 25 items underwent content and semantic changes in the content and face validation panels, being reorganized into a second version with 22 items. In the reevaluation, participants considered 21 questions to be clear and representative of the Brazilian Dietary Guidelines, with one being excluded. This third version of the instrument underwent confirmatory factor analysis after being applied online with 209 PHC workers from all Brazilian macroregions. We excluded five items in this analysis: four due to bivariate empty cells and one due to low discrimination capacity. The final model, with 16 items loaded onto one dimension, returned good fit indices [χ2(104) = 119.047, p = 0.1486; RMSEA = 0.026 (90% CI = 0.000 to 0.046), Cfit = 0.979; CFI = 0.924; TLI = 0.913]; its information peak was below average. CONCLUSIONS The instrument proved to be valid and accurate for assessing PHC workers with below average knowledge of the Brazilian Dietary Guidelines. It might contribute to improving actions to promote healthy eating in Brazilian PHC settings by identifying the need for training health professionals.

Dental caries surveys: considerations about reproducibility / Inquéritos de cárie dentária: considerações sobre a reprodutibilidade

Aim:To evaluate the impact of the recording of teeth whose clinical conditions rarely vary (anterior teeth and third molars) in inter-examiner agreement measurements. Methods:Clinical data from 56 schoolchildren, 12 years of age, previously collected by two examiners, according to the "Oral Health Surveys: basic methods" codes and criteria, were analyzed in the present study. The effects from including/excluding such teeth upon reproducibility were measured by general percentage agreement (GPA) and Kappa statistics (к) performances. Results: The exclusion of anterior teeth associated with the inclusion of third molars produced a decrease in GPA that was simultaneous to an increase in the weighted Kappa (nominal data) and simple (dichotomous data) values. The incorrect inclusion of third molars (GPA = 100%; к = + 1) in the reproducibility measurement artificially increased the inter-examiner Kappa values. Conclusion: The inclusion/exclusion of anterior teeth and third molars, seeking a more reliable agreement among examiners, can have a positive or negative impact on the measured reproducibility values. A clear warning about the impact of including third molars in the reproducibility measurement, in the 12 years old age group, should be performed in "Oral Health Surveys: basic methods" and similar manuals.

Objetivo: Avaliar o impacto do registro de dentes anteriores e terceiros molares, cujas condições clínicas pouco variam, sobre as mensurações de concordância inter-examinadores. Métodos: Dados clínicos de 56 escolares de 12 anos de idade, previamente coletados por 2 examinadores, segundo os códigos e critérios expressos no "Levantamentos em Saúde Bucal: métodos básicos" foram analisados neste estudo. Os efeitos da inclusão/exclusão destes dentes sobre a concordância inter-examinadores foram mensurados calculando-se a porcentagem geral de concordância (GPA) e estatística Kappa (к). Resultados:A inclusão de terceiros molares aumentou a GPA para dados dicotomizados ou não. A exclusão de dentes anteriores diminuiu a GPA para dados dicotomizados ou não. Quando associada à inclusão de terceiros molares, sob perfeita concordância (к = +1), os valores de Kappa foram artificialmente aumentados tanto para dados dicotomizados quanto não-dicotomizados. Conclusão: A inclusão/exclusão de dentes anteriores e/ou de terceiros molares, no sentido de se evidenciar melhor as discordâncias entre examinadores, podem impactar positiva ou negativamente sobre a fidedignidade da reprodutibilidade mensurada. Uma advertência clara sobre o impacto da inclusão dos dentes terceiros molares no cálculo da reprodutibilidade, para a faixa etária de 12 anos, deveria estar presente no "Levantamentos em Saúde Bucal: métodos básicos" e manuais semelhantes.

Translation, Cross-cultural Adaptation and Reliability Analysis of the Survey of Anxiety and Information for Dentists (SAID) among Brazilian Adolescents

ABSTRACT Objective: To translate, perform a cross-cultural adaptation and reliability analysis of the Survey of Anxiety and Information for Dentists (SAID) for use with Brazilian adolescents. Material and Methods: The SAID was translated into Brazilian Portuguese and back-translated to English. An expert committee compared both versions and examined their equivalence. Then, a face validation was performed with 10 adolescents. The SAID was applied in printed format with 25 questions. Participants answered and commented on the questions with a researcher to confirm the understanding and provide suggestions. The suggestions were implemented, and the expert committee approved the final version of the SAID in Brazilian Portuguese. The psychometric properties were tested with 60 adolescents aged 10 to 19 years. Participants answered the Brazilian version of the SAID before their first dental appointment and two weeks later to determine test-retest reliability. Reliability was analyzed by internal consistency analysis (Cronbach's alpha) and test-retest (ICC). Results: The instrument presented excellent reliability according to internal consistency (Cronbach's alpha = 0.77) and test-retest coefficients (ICC = 0.88; 95% CI: 0.81-0.93). The Kappa coefficients and the degree of agreement of the dichotomous questions indicated good reproducibility of the new version. Conclusion: The SAID translation, cross-cultural adaptation and reliability analysis were completed successfully. Thus, the Brazilian version of the SAID can be a useful survey tool for dental care of adolescent patients.

Malocclusion Impact Scale for Early Childhood (MIS-EC): development and validation

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

YouTube™ and oral lichen planus: an appraisal of the educational quality of information

Abstract: The objective of this study was to analyze the quality of videos on oral lichen planus (OLP) available in YouTube™. A cross-sectional analytical study was conducted by searching the video sharing platform YouTube™. Videos aimed at clarifying the etiological and clinical characteristics, diagnostic criteria, treatment, and prognosis of OLP were included. A total of 481 videos were retrieved and 37 were included in the study according to the selection criteria established. Most of the videos evaluated (86.5%; n = 32) were produced by independent users. The average reliability was 1.8 and quality assessment classified only three videos (8.1%) as having good/excellent quality. A significant correlation was observed between the length of the video analyzed and its quality and reliability (p < 0.05), as well as between the reliability and usefulness of the video (p = 0.03). YouTube™ has become a leading source of information for the general population. However, a significant number of these videos have a low quality. Students, professionals, and healthcare providers must be more actively involved in providing clear, accurate, and reliable evidence-based information in an accessible language in order to enable significant improvement in patient care delivery.

Two validity evidences of the ESQUADA and Brazilians' dietary quality levels / Duas evidências de validade da ESQUADA e níveis de qualidade da dieta dos brasileiros

ABSTRACT OBJECTIVE Assess two validity evidences of the diet quality scale (ESQUADA) for the selection of items with better discrimination of the Brazilians' diet quality and propose a description in score levels. METHODS Brazilian adolescents and adults residing in the country (n = 2,059) answered an online questionnaire with 52 items, shared on social networks and email lists between March and April 2018. Statistical tests were applied to analyze the validity and reliability of the instrument's evidence. Factor analysis was applied to study the dimensionality of the questionnaire items. Item response theory was applied to identify the discrimination and location of items on the continuum, construct the scale and assess the differential item functioning in terms of sex and age. RESULTS Among the 52 items of the questionnaire, 25 had greater measurement accuracy, with adequate adjustment and reliability. The item on the habit of eating ultra-processed foods at home showed the best discrimination of diet quality. No item showed differential functioning regarding sex and age. In the construction of the ESQUADA, five diet quality levels were identified: very poor, poor, good, very good and excellent. It was observed that while breakfast cereals and/or cereal bars are more frequently consumed by individuals with "very poor" diet quality; nuts and/or walnuts are most often consumed by those individuals with "excellent" diet quality. CONCLUSION The ESQUADA consists of 25 precise items with no differential functioning to assess the quality of Brazilians' diet. The construction of the ESQUADA made it possible to recognize food consumption and dietary practices characteristic of each level of diet quality.

RESUMO OBJETIVO Avaliar duas evidências de validade da escala de qualidade da dieta (ESQUADA) para seleção dos itens com melhor discriminação da qualidade da dieta dos brasileiros e propor uma descrição em níveis de escore. MÉTODOS Adolescentes e adultos brasileiros e residentes no país (n = 2.059), responderam a um questionário on-line com 52 itens, compartilhado em redes sociais e listas de correio eletrônico entre março e abril de 2018. Foram aplicados testes estatísticos para análise de evidências de validade e confiabilidade do instrumento. A análise fatorial foi aplicada para estudo da dimensionalidade dos itens do questionário. A teoria de resposta ao item foi aplicada para identificar a discriminação e localização dos itens no continuum , construir a escala e avaliar o comportamento diferencial dos itens quanto ao sexo e idade. RESULTADOS Dentre os 52 itens do questionário, 25 apresentaram maior precisão de medida, com ajuste e confiabilidade adequados. O item sobre o costume de comer alimentos ultraprocessados em casa apresentou a melhor discriminação da qualidade da dieta. Nenhum item apresentou comportamento diferencial quanto a sexo e idade. Na construção da ESQUADA foram identificados cinco níveis de qualidade da dieta: "muito ruim", "ruim", "boa", "muito boa" e "excelente". Observou-se que enquanto cereais matinais e/ou barrinhas de cereais são consumidos com maior frequência por indivíduos com qualidade da dieta "muito ruim"; castanhas e/ou nozes são consumidos mais frequentemente por aqueles indivíduos com qualidade da dieta "excelente". CONCLUSÕES A ESQUADA é composta por 25 itens precisos e sem comportamento diferencial para avaliar a qualidade da dieta dos brasileiros. A construção da ESQUADA possibilitou reconhecer consumo e práticas alimentares característicos de cada nível de qualidade da dieta.

What, what for and how? Developing measurement instruments in epidemiology / O quê, para quê e como? Desenvolvendo instrumentos de aferição em epidemiologia

ABSTRACT The development and cross-cultural adaptation of measurement instruments have received less attention in methodological discussions, even though it is essential for epidemiological research. At the same time, the quality of epidemiological measurements is often below ideal standards for the construction of solid knowledge on the health-disease process. The scarcity of systematizations in the field about what, what for, and how to adequately measure intangible constructs contributes to this scenario. In this review, we propose a procedural model divided into phases and stages aimed at measuring constructs at acceptable levels of validity, reliability, and comparability. Underlying our proposal is the idea that not only some but several connected studies should be conducted to obtain appropriate measurement instruments. Implementing the model may contribute to broadening the interest in measurement instruments and, especially, addressing key epidemiological problems.

RESUMO Embora fundamental para a pesquisa epidemiológica, o desenvolvimento e a adaptação transcultural de instrumentos de aferição têm recebido menos destaque nas discussões metodológicas que permeiam o campo. Em paralelo, a qualidade das mensurações realizadas em muitos estudos epidemiológicos está frequentemente aquém do desejado para a construção de conhecimento sólido sobre o processo saúde-doença. A escassez de sistematizações sobre o que, para que e como aferir na área provavelmente contribui para esse cenário. Nesta revisão, propomos um modelo processual composto por uma sequência de etapas voltadas à mensuração de construtos em níveis aceitáveis de validade, confiabilidade e, por extensão, comparabilidade. Subjaz à proposta a ideia de que não apenas alguns, mas diversos estudos concatenados entre si e sucessivamente mais aprofundados devem ser conduzidos para obter aferições adequadas. A implementação do modelo poderá contribuir para alargar o interesse sobre instrumentos de aferição e, especialmente, para enfrentar os problemas investigados em epidemiologia.

Validity and reliability of a trigonometry-based method for the measurement of tooth movement on digital models

ABSTRACT Objective: The objectives of the present study were to develop a method for longitudinally measuring tooth rotation, inclination and angulation on digital models, and to test the method validity and reliability. Methods: The initial and final planned models of 14 patients treated with Invisalign® (386 teeth) were exported from ClinCheck®. The rotation, inclination and angulation values were assessed for the incisors, canines, premolars and molars, in both models, using trigonometry. An application was developed in Python 2.7 to automate the measurements. The ∆planned (variation in the position between the initial and final planned models) was obtained for each tooth and each type of movement. To test the validity, the degree of agreement between the ∆planned and the values available in the Invisalign® Table of Movements was assessed using the Intraclass Correlation Coefficient (ICC) and Bland-Altman analysis. For intra and inter-rater reliabilities, the ∆planned was obtained again. Results: Excellent ICCs (> 0.9) and limits of agreement with narrow and clinically acceptable discrepancies were obtained for the rotation of all teeth (except maxillary canines, which had broader limits: -3.47 - 5.43) and for the inclination of premolars and molars. The inclination of anterior teeth and angulation of all teeth had ICCs and limits that were not indicative of great agreement. The reliability was high for the three movements (discrepancy <2°). Conclusions: The method developed is reliable and suitable for longitudinally measuring inclination (posterior teeth) and rotation (except maxillary canines). It has limited value for the other movements measurements.

RESUMO Objetivo: Os objetivos do presente estudo foram desenvolver um método para medir longitudinalmente a rotação, inclinação e angulação dentárias em modelos digitais, e testar sua validade e reprodutibilidade. Material e Métodos: Os modelos inicial e final planejado de 14 pacientes tratados com Invisalign® (386 dentes) foram exportados do ClinCheck®. Os valores de rotação, inclinação e angulação foram calculados para incisivos, caninos, pré-molares e molares, em ambos os modelos, por meio de trigonometria. Um aplicativo desenvolvido em Python 2.7 foi utilizado para automatização das medidas. O ∆planejado (variação na posição entre os modelos inicial e final planejado) foi obtido para os movimentos descritos, nos diferentes grupos de dentes. A validade do método foi verificada pelo grau de concordância entre o ∆planejado e os valores disponíveis na Tabela de Movimentos do Invisalign®, utilizando-se o Coeficiente de Correlação Intraclasse (ICC) e a análise de Bland-Altman. O ∆planejado foi novamente calculado para análise da reprodutibilidade intra e interexaminadores. Resultados: Excelentes ICCs (> 0,9) e limites de concordância com discrepâncias reduzidas e clinicamente aceitáveis foram obtidos para a rotação de todos os dentes (exceto os caninos superiores, que expressaram limites mais amplos: -3,47 - 5,43) e para a inclinação de pré-molares e molares. A inclinação dos dentes anteriores e a angulação de todos os dentes apresentaram ICCs e limites não representativos de boa concordância. A reprodutibilidade foi alta para os três movimentos (discrepância < 2°). Conclusões: O método desenvolvido é reprodutível e se mostrou adequado para mensuração longitudinal da inclinação de dentes posteriores e rotação de todos os dentes, exceto caninos superiores. Apresenta valor limitado para as demais mensurações.
