ABSTRACT

As drogas utilizadas para prevenção de convulsões podem impactar na movimentação dentária durante o tratamento ortodôntico. O objetivo deste estudo foi avaliar a influência de drogas anticonvulsivantes no tratamento ortodôntico. O desenho deste estudo é uma revisão narrativa da literatura onde uma busca eletrônica foi realizada sem restrição de idioma e data em três bases de dados (PubMed via MEDLINE, SCOPUS e BVS). Foram utilizados os seguintes termos para o PubMed e BVS: anticonvulsants drugs AND orthodontic movement e para o SCOPUS: anticonvulsants AND drugs AND orthodontic AND movement. Uma pesquisa complementar foi realizada nas referências bibliográficas dos estudos incluídos. Os artigos indicaram que o uso de medicação anticonvulsivante favorece o desenvolvimento de hiperplasias gengivais, xerostomia e alterações no metabolismo ósseo que modulam a taxa de movimentação ortodôntica. Dentro das limitações desta revisão, concluiu-se que não há contraindicações para tratamento ortodôntico em pacientes utilizando anticonvulsivantes, no entanto os ortodontistas devem estar cientes dos potenciais efeitos adversos advindos do uso desses medicamentos para que possam adotar medidas para mitigar esses riscos.


Drugs used to prevent seizures can have an impact on tooth movement during orthodontic treatment. This study aimed to evaluate the influence of anticonvulsant medications on orthodontic treatment. The design of this study is a narrative literature review in which an electronic search was carried out without language or date restriction in three databases (PubMed/MEDLINE, SCOPUS, and BVS). The following terms were used for PubMed and BVS: anticonvulsants drugs AND orthodontic movement and SCOPUS: anticonvulsants AND drugs AND orthodontic AND movement. A complementary search was carried out on the bibliographical references of the included studies. The articles indicated that using anticonvulsant medication favors the development of gingival hyperplasia, xerostomia, and alterations in bone metabolism that modulate the rate of orthodontic movement. Within the limitations of this review, it was concluded that there is no contraindication for orthodontic treatment in patients using anticonvulsants. However, orthodontists should be aware of the potential adverse effects arising from the use of these drugs so that they can adopt measures to minimize these risks.

ABSTRACT

Aim: this study is to evaluate the effect of corrosion on flexural fracture resistance in orthodontic mini-implants composed of two materials and submerged in salivary substitutes with or without fluoride. Methods: twenty mini-implants were used, 10 from SIN Company (Ti6AL4V alloys) and 10 from Morelli (steel alloys), (G1: Ti6AL4V in fluoride-free saliva solution; G2: Ti6AL4V in saliva solution with 1500 ppm of fluoride; G3: Steel in saliva without fluoride; and G4: Steel in saliva with 1500 ppm of fluoride). The samples were taken to a potentiostat to evaluate the corrosion, and then were evaluated under scanning electron microscopy (SEM). Then, the mini-implants underwent flexural fracture resistance tests. Kruskal-Wallis test with the Student-Newman-Keuls comparison evaluated the corrosion and pitting potentials of each group. ANOVA and Tukey's comparison test at a 1% significance level. Results: All groups suffered corrosion potential and pitting potential, but those that were in solutions with the presence of fluoride showed less resistance to the formation of corrosion pits (G1 and G3). In the SEM analysis after flexural resistance, small cavities suggestive of pitting corrosion were noted. The G4 was the only one that formed the passivation potential. In the fracture resistance test, mini-implants manufactured by Ti6AL4V fractured with less force applied (G1 and G2). Most steel mini-implants (G3 and G4) only deformed with a higher force application. Conclusion: Fluoride acts to corrode mini-implants, regardless of their manufacturing material. Regarding flexural resistence, the corrosion rate of the mini implants did`nt influence the fracture resistance values

ABSTRACT

El objetivo de este estudio fue describir las alternativas terapéuticas ortodóncico-quirúrgicas más utilizadas en la actualidad para el manejo de la displasia cleidocraneal en pacientes en crecimiento. Se realizó una búsqueda de literatura durante mayo de 2023 en las bases de datos Pubmed, Epitemonikos, Dentistry & Oral Sciences Source y LILACS sobre reporte de casos que presentaran estrategias de tratamiento ortodóncico-quirúrgico en pacientes menores de 18 años con displasia cleidocraneal. Seis artículos cumplieron con los criterios de inclusión. De ellos se obtuvieron siete reportes de casos. Las edades de los pacientes fluctúan entre los 10 y 16 años. Las estrategias de tratamiento consisten en al menos dos etapas de tratamiento ortodóncico quirúrgicas que involucran la extracción de dientes primarios y supernumerarios y la exposición quirúrgica de dientes permanentes retenidos para permitir su erupción y/o su tracción ortodóncica. Algunos casos son finalizados con cirugía Ortognática (Osteotomía Le Fort I de avance maxilar). La extracción de dientes primarios y supernumerarios, fenestración y tracción ortodóncica de los dientes permanentes retenidos y la cirugía ortognática al finalizar el crecimiento (cuando sea necesario) se propone actualmente como la mejor alternativa terapéutica para el tratamiento de pacientes con displasia cleidocraneal.


The objective of this study was to describe the orthodontic-surgical therapeutic alternatives most used nowadays, for the management of CCD in growing patients. A literature search for case reports was carried out through May, 2023 in PubMed, Epitemonikos, Dentistry & Oral Sciences Source and LILACS databases. We included case reports that presented complete orthodontic-surgical treatment strategies in patients with DCC under 18 years of age. Six articles met the inclusion criteria and seven case reports were identified. The age of cases ranged from 10 to 16 years. Treatment strategies consisted of at least two stages of surgical orthodontic treatment involving extraction of primary and supernumerary teeth and surgical exposure of impacted permanent teeth to allow spontaneous eruption or orthodontic traction. Some cases were completed with orthognathic surgery. Extraction of primary and supernumerary teeth, fenestration and orthodontic traction of retained permanent teeth and orthognathic surgery at the end of growth (when necessary) is currently proposed as the best therapeutic alternative for the treatment of patients with DCC.

ABSTRACT

The aim of this study was to evaluate the effectiveness of motivational interviewing on improving oral hygiene behavior in patients with fixed orthodontics appliances. A parallel-group randomized clinical trial was conducted with 45 patients of the Orthodontic Clinic of Unibe's Postgraduate Unit. A computer-generated list of numbers created with SPSS V21.0 was used to randomly allocate participants into the experimental or the control group. Monthly oral hygiene instructions and an oral hygiene kit from GUM® with special orthodontic hygiene tools were given to the participants. Furthermore, the experimental group underwent motivational interviewing sessions facilitated by a periodontist who received training from two expert psychologists. These psychologists also provided supervision to the interviewer, ensuring the accurate implementation of the intervention. Simplified Oral Hygiene Index (SOHI), Gingival Index (GI), Periodontal Probing Depth (PPD) and Bleeding on Probing (BoP) were recorded at baseline, three and six months after the beginning of the study. The participant and the evaluator (another periodontist who recorded the data) were masked. Repeated-measures mixed- model analysis of variance and chi-squared test were conducted. Mean SOHI, GI, PPD and BoP scores did not differ significantly across the three time points (baseline, three and six months). Nevertheless, a significant interaction on SOHI scores (F (2, 58) = 3.463, p = .038, h2 = .052) was found between the sessions and the treatment conditions (experimental vs control group) at the third and sixth month. Motivational interviewing plus oral hygiene instructions appears to maintain a better control of dental biofilm and calculus in comparison with conventional oral hygiene instructions alone.


El objetivo de este trabajo fue evaluar la efectividad de las entrevistas motivacionales para mejorar el comportamiento de higiene oral en pacientes con aparatos ortodóncicos fijos. Se llevó a cabo un ensayo clínico aleatorizado de grupos paralelos con 45 pacientes de la Clínica de Ortodoncia de la Unidad de Posgrado de Unibe. Se utilizó una lista de números generada por computadora con SPSS V21.0 para asignar aleatoriamente a los participantes al grupo experimental o de control. Se les proporcionó a los participantes instrucciones mensuales de higiene oral y un kit de higiene oral de GUM® con utensilios de higiene especiales para ortodoncia. Además, el grupo experimental recibió sesiones de entrevista motivacional facilitadas por un periodoncista capacitado por dos psicólogas expertas. Estas psicólogas también supervisaron al entrevistador, asegurando la implementación precisa de la intervención. Se registró el Índice Simplificado de Higiene Oral (IHO-S), el Índice Gingival (IG), la Profundidad de Sondaje Periodontal (PS) y el Sangrado al Sondaje (SS) al inicio, a los tres y seis meses después del inicio del estudio. Tanto el participante como el evaluador (otro periodoncista que registró los datos) estaban enmascarados. Se realizaron análisis de varianza de medidas repetidas con modelo mixto y pruebas de chi-cuadrado. Las puntuaciones medias del IHO-S, IG, PS y SS no difirieron significativamente en los tres momentos (inicio, tres y seis meses). Sin embargo, se encontró una interacción significativa en las puntuaciones del IHO-S (F (2, 58) = 3.463, p = .038, h2 = .052) entre las sesiones y las condiciones de tratamiento (grupo experimental vs grupo de control) en el tercer y sexto mes. Las entrevistas motivacionales junto con las instrucciones de higiene oral parecen mantener un mejor control de la biopelícula dental y el cálculo en comparación con las instrucciones convencionales de higiene oral por sí solas.

ABSTRACT

Este Estudio tuvo por objetivo determinar la incidencia de reabsorción radicular externa en premolares superiores e inferiores permanentes al finalizar el tratamiento de ortodoncia. Esta investigación fue realizada en pacientes entre 18 y 35 años que recibieron tratamiento de ortodoncia, sin extracciones, con técnica de autoligado en la ciudad de Guadalajara. Se consideraron 120 premolares, realizando mediciones longitudinales en las tomografías computarizadas de haz cónico al inicio y término del tratamiento. Utilizando el software Implant Viewer 3. Los valores registrados en el primer y segundo premolar superior tanto del lado derecho como izquierdo al inicio y término del tratamiento fluctuaron entre -4.946 y -7.801; p ≤ 0.0005 encontrándose diferencias estadísticas significativas. Mientras que en el primer y segundo premolar inferior tanto del lado derecho como izquierdo, fluctuaron entre -4.864 y -5.28; p ≤ 0.0005 encontrándose diferencias estadísticas significativas. Se concluye en este estudio que los dientes sometidos a movimientos durante el tratamiento de ortodoncia sufren modificaciones en el contorno de la raíz, cambios con consecuencias mínimas que no comprometen la funcionalidad del diente. Los premolares superiores presentaron mayores rangos de reabsorción radicular que los premolares inferiores.


The aim of this study is to determine the incidence of root resorption in permanent upper and lower premolars at the end of an orthodontic treatment. This research was carried out in patients aged between 18 and 35 years old who received orthodontic treatment, without extractions, with a self-ligating technique in the city of Guadalajara, Mexico. In this study, 120 premolars were considered, making longitudinal measurements with cone beam computed tomography at the beginning and the end of the treatment, using the Implant Viewer 3 software. The values recorded in the upper first and second premolars on both the right and left sides at the beginning and the end of the treatment fluctuated between -4.946 and -7.801; p ≤ 0.0005, finding statistically significant differences. In the lower first and second premolars on both the right and left sides, they fluctuated between -4.864 and -5.28; p ≤ 0.0005, also finding statistically significant differences. It is concluded that teeth subjected to movements during orthodontic treatment suffer modifications in the contour of the root, changes with minimal consequences that do not compromise their functionality. The upper premolars showed higher ranges of root resorption than the lower premolars.

ABSTRACT

El presente reporte tiene como objetivo presentar de manera secuencial y visual la protracción maxilar de un paciente clase III esqueletal, utilizando el protocolo BAMP. Una vez realizado el análisis clínico del caso se decidió realiza un tratamiento ortopédico a través del uso de miniplacas de titanio con elásticos intermaxilares de clase III siguiendo el protocolo BAMP, junto a un tratamiento ortodóncico dento alveolar con aparatología fija bimaxilar prescripción Roth 0.22" Mini sprint forestadent. Se observa el éxito del enfoque interceptivo utilizando el protocolo BAMP. Este enfoque logró reducir tanto el tiempo como la complejidad del tratamiento ortodóncico, y también disminuyó la necesidad de someterse a una cirugía ortognática en la edad adulta. El tratamiento BAMP, diseñado para ciertas edades y crecimiento, se demostró exitoso en un paciente de 12 años sin potencial de crecimiento. Las miniplacas como anclaje son efectivas para protracción maxilar en varios casos, aunque se necesita seguimiento y educación postquirúrgica. Se recomienda retirar las miniplacas cuando no sean necesarias, adaptando el protocolo a cada paciente. En resumen, el tratamiento con miniplacas es eficaz para corregir anomalías Clase III esqueléticas.


The present report aims to sequentially and visually present the maxillary protraction of a Class III skeletal patient using the BAMP protocol. After conducting a clinical analysis of the case, it was decided to perform orthopedic treatment using titanium miniplates with Class III intermaxillary elastics following the BAMP protocol, in conjunction with dentoalveolar orthodontic treatment using fixed bimaxillary appliances with Roth prescription 0.022" Mini Sprint Forestadent. The success of the interceptive approach using the BAMP protocol is observed. This approach managed to reduce both the time and complexity of orthodontic treatment and also decreased the need for orthognathic surgery in adulthood. The BAMP treatment, designed for specific ages and growth stages, proved successful in a 12-year-old patient without growth potential. Miniplates as anchorage are effective for maxillary protraction in various cases, although post-surgical follow-up and education are required. It is recommended to remove the miniplates when they are no longer necessary, adapting the protocol to each patient. In summary, miniplate treatment is effective in correcting Class III skeletal anomalies.

ABSTRACT

Objective: Malocclusion affects aesthetics, the physical, psychological and social life of a person. The aim of this study was to evaluate the awareness of malocclusion and attitude towards orthodontic treatment among trainee dental surgery technicians in Nigeria. Materials and Methods: This was a descriptive cross-sectional study carried out among 68 final year (sixty-eight) trainee dental surgery technicians in Nigeria. The research instrument was a self-administered close ended questionnaire. Data was analyzed using SPSS version 20. P value (P<0.05) was regarded as significant. Results: Sixty-one (89.7%) of the respondents were females, while 7 (10.3%) were males. Fifty-seven (83.8%) have heard of the term malalignment of teeth, 53 (77.9%) of the students think malalignment is due to external habits. 61 (89.7%) are aware that few teeth may have to be removed for proper positioning of irregular teeth and 51 (75.0%) were aware that the irregular teeth can be corrected even after 40 years of age. More females were aware of malocclusion and had positive attitude towards orthodontic procedures when compared to the males, but the difference was not statistically significant (P>0.05).Conclusion. Majority of the respondents in this study were aware of the term malalignment and had positive attitude towards orthodontic treatment. More females constituted the study population.

ABSTRACT

Nanoparticles (NPs) are insoluble particles with a diameter of fewer than 100 nanometers. Two main methods have been utilized in orthodontic therapy to avoid microbial adherence or enamel demineralization. Certain NPs are included in orthodontic adhesives or acrylic resins (fluorohydroxyapatite, fluorapatite, hydroxyapatite, SiO2, TiO2, silver, nanofillers), and NPs (i.e., a thin layer of nitrogen-doped TiO2 on the bracket surfaces) are coated on the surfaces of orthodontic equipment. Although using NPs in orthodontics may open up modern facilities, prior research looked at antibacterial or physical characteristics for a limited period of time, ranging from one day to several weeks, and the limits of in vitro studies must be understood. The long-term effectiveness of nanotechnology-based orthodontic materials has not yet been conclusively confirmed and needs further study, as well as potential safety concerns (toxic effects) associated with NP size.


Nanopartículas (NPs) são partículas insolúveis com diâmetro inferior a 100 nanômetros. Dois métodos principais têm sido utilizados na terapia ortodôntica para evitar a aderência microbiana ou a desmineralização do esmalte: NPs são incluídas em adesivos ortodônticos ou resinas acrílicas (fluoro-hidroxiapatita, fluorapatita, hidroxiapatita, SiO2, TiO2, prata, nanopreenchimentos) e NPs são revestidas nas superfícies de equipamentos ortodônticos, ou seja, uma camada fina de TiO2 dopado com nitrogênio nas superfícies do braquete. Embora o uso de NPs em ortodontia possa tornar acessível modernos recursos, pesquisas anteriores analisaram as características antibacterianas ou físicas por um período limitado de tempo, variando de 24 horas a várias semanas, por isso devem ser compreendidos os limites dos estudos in vitro. A eficácia de longo prazo de materiais ortodônticos com base em nanotecnologia ainda não foi confirmada de forma conclusiva, o que exige mais estudos, bem como potenciais preocupações de segurança (efeitos tóxicos) associadas ao tamanho da NP.

ABSTRACT

ABSTRACT Objective: To assess the methodological quality and characteristics of systematic reviews (SRs) of interventional studies in orthodontics and assess how the certainty of the evidence is reported using the GRADE approach. Material and Methods: Six electronic databases were searched, followed by a hand search of the reference lists of eligible studies (PROSPERO #CRD42020180852). The required study design was randomized and nonrandomized studies of interventions published between January 2019 and May 2020. The Assessing the Methodological Quality of Systematic Reviews (AMSTAR 2) tool was used for the quality appraisal of the included SRs. Paired reviewers independently screened the studies, extracted data, and appraised the methodological quality. Results: The study included 46 SRs; 19.5% had moderate to high methodological quality, and the remaining had low to critically low methodological quality. Fifty-four percent of the reviews assessed the certainty of evidence using the GRADE approach, and 34.8% followed all GRADE criteria. Conclusion: Most reviews had a good judgment of the AMSTAR2 items, although some critical items contributed to decreased overall quality. Half of the reviews used the GRADE approach to assess the certainty of the evidence, and this approach should be included in future systematic reviews of interventions.

ABSTRACT

Objective: to evaluate the phenotypic characteristics of the mandible in Class III malocclusion in lateral cephalometric radiographs (LCR) and anteroposterior radiographs (APR). Materials and Methods: this is a retrospective observational study with a convenience sample. Individuals with Class III malocclusion were evaluated in 80 LCR (31 females and 49 males) and 70 APR (25 females and 45 males). In the control group, individuals with excellent occlusion were analyzed in 20 LCR and 20 APR (10 of each sex). The linear and angular measurements of the samples were tabled and submitted to the Shapiro-Wilk statistical test. Once their asymmetric distribution was known, the Mann-Whitney U test was selected for comparison between groups and sexes, in addition to Pearson's correlation coefficient test. Results: the length of the mandibular body, height of the ramus, height of the mandibular symphysis and alveolar processes, intercondylar distance, intergonion, and total length of the mandible were structural characteristics involved in the constitution of the skeletal disorder studied. Moreover, the spatial location of the mandible in relation to the maxilla and the base of the skull showed a strong influence on the configuration of this craniofacial disorder, evidenced by the protrusion of the mandible, an evident phenotype of the participation of this bone in Class III skeletal malocclusion. Conclusion: the involvement of structural and spatial characteristics of the mandible in relation to the maxilla and the cranial base in the constitution of Class III skeletal malocclusion was evident.


Objetivo: avaliar as características fenotípicas da mandíbula na má oclusão de Classe III em radiografias cefalométricas laterais (LCR) e radiografias anteroposteriores (APR). Materiais e Métodos: trata-se de um estudo observacional retrospectivo com amostra de conveniência. Indivíduos com má oclusão de Classe III foram avaliados em 80 LCR (31 mulheres e 49 homens) e 70 APR (25 mulheres e 45 homens). No grupo controle, foram analisados ​​indivíduos com excelente oclusão em 20 LCR e 20 APR (10 de cada sexo). As medidas lineares e angulares das amostras foram tabuladas e submetidas ao teste estatístico Shapiro-Wilk. Conhecida sua distribuição assimétrica, foi selecionado o teste U de Mann-Whitney para comparação entre grupos e sexos, além do teste do coeficiente de correlação de Pearson. Resultados: o comprimento do corpo mandibular, altura do ramo, altura da sínfise mandibular e dos processos alveolares, distância intercondilar, intergônio e comprimento total da mandíbula foram características estruturais envolvidas na constituição da desordem esquelética estudada. Além disso, a localização espacial da mandíbula em relação à maxila e à base do crânio apresentou forte influência na configuração desta desordem craniofacial, evidenciada pela protrusão da mandíbula, fenótipo evidente da participação deste osso na Classe III má oclusão esquelética. Conclusão: ficou evidente o envolvimento das características estruturais e espaciais da mandíbula em relação à maxila e à base do crânio na constituição da má oclusão esquelética de Classe III.

ABSTRACT

Os dispositivos de ancoragem temporária ou mini-implantes adquirem cada vez mais relevância no manejo clínico dos tratamentos ortodônticos. Entretanto, apesar dos resultados clínicos expressivos obtidos, algumas intercorrências podem acometer a ancoragem no decorrer do tratamento. Os insucessos podem estar associados a fatores relacionados ao profissional, ao paciente ou ao próprio parafuso. Outrossim, existem fatores que podem contribuir para o sucesso clínico na utilização destes dispositivos, como a seleção apropriada do comprimento do mini-implante, a escolha de áreas adequadas para inserção do dispositivo, além de conhecimentos acerca da densidade óssea, de forma a contribuir para a estabilidade primária, a prática de bons hábitos de higiene bucal ou ainda a utilização de dispositivos autoperfurantes. Assim, o presente estudo propôs-se a revisar a literatura científica disponível acerca de mini-implantes com artigos científicos selecionados utilizando as bases de dados PubMed, Scopus, Web of Science, Cochrane Library, Embase, BVS, Opengrey, Google Scholar e Catálogo de teses e dissertações. Após aplicados os critérios de seleção, 32 artigos foram selecionados para compor este trabalho. Conclui-se que a utilização dos mini-implantes mantém o controle ideal da ancoragem, de modo a evitar movimentações dentárias indesejáveis, sendo inegável o sucesso clínico dos dispositivos de ancoragem temporária na Ortodontia. Entretanto, é comprovado que complicações cuja etiologia pode variar entre profissional, paciente ou o próprio parafuso são capazes de acometer a ancoragem no decorrer do tratamento ortodôntico, de modo a implicar falhas e insucesso dos miniparafusos.

ABSTRACT

Introdução: Considerando que a creatina (Cr) pode interferir em diversos aspectos do metabolismo ósseo, tem sido questionado se tal substância poderia influenciar também na movimentação ortodôntica, uma vez que esse processo depende do turnover ósseo, com aposição de osso na região alveolar e reabsorção óssea no lado oposto. Objetivo: Avaliar o efeito da creatina sobre a movimentação ortodôntica em ratos, considerando a quantidade de movimentação dentária, o volume ósseo alveolar e a remodelação óssea. Metodologia: Trata-se de um estudo experimental, in vivo, controlado, com base descritiva e inferencial. A amostra foi constituída de 30 ratos machos Wistar (Ratus norvegicus albinus), saudáveis, com idade variando entre 7 e 12 semanas, os quais foram submetidos à movimentação dentária ortodôntica contínua dos primeiros molares permanentessuperiores, do lado esquerdo, durante um período de 21 dias. Os ratos foram divididos aleatoriamente em 3 grupos: Grupo controle (GC) - ratos submetidos apenas à movimentação ortodôntica e à ingestão diária de água (n=8); Grupo experimental creatina 1 (GEC1) - ratos submetidos à movimentação ortodôntica e à dose diária de 21mg/kg de creatina (n=10) e Grupo experimental creatina 2 (GEC2) - ratos submetidos à movimentação ortodôntica e à dose diária de 51 mg/kg de creatina (n=12). A análise da quantidade de movimentação dentária e do volume ósseo alveolar foi realizada por meio da microtomografia computadorizada. Para investigar a remodelação óssea foi realizado um estudo morfológico, pelo método da Hematoxilina-Eosina (HE). Na análise estatística foi utilizado o teste ANOVA unidirecional, seguido pelo teste de Tukey com intervalo de confiança de 95%. Resultados: Não houve diferenças estatisticamente significativas (p>0,05) entre o grupo controle e os grupos experimentais em relação a quantidade de movimentação dentária, ao volume ósseo alveolar e a remodelação óssea dos ratos submetidos a movimentação ortodôntica. Conclusão: Os achados deste estudo sugerem que a creatina não afeta a movimentação ortodôntica nas doses testadas (AU).


Introduction:Considering that creatine (Cr) can interfere in several aspects of bone metabolism, it has been questioned whether this substance could also influence orthodontic movement, since this process depends on the shiftseebone, with bone apposition in the alveolar region and bone resorption on the opposite side. Objective: To evaluate the effect of creatine on orthodontic tooth movement in rats, considering the amount of tooth movement, alveolar bone volume and bone remodeling. Methodology: This is an experimental, in vivo, controlled study, with a descriptive and inferential basis. The sample consisted of 30 healthy male Wistar rats (Ratus norvegicus albinus), aged between 7 and 12 weeks, which were subjected to continuous orthodontic tooth movement of the upper first permanent molars, on the left side, for a period of 21 days. The rats were randomly divided into 3 groups: Control group (CG) - rats subjected only to orthodontic movement and daily water intake (n=8); Experimental group creatine 1 (GEC1) - rats subjected to orthodontic tooth movement and a daily dose of 21 mg/kg of creatine (n=10); and Experimental group creatine 2 (GEC2) - rats subjected to orthodontic tooth movement and a daily dose of 51 mg/kg of creatine (n=12). The analysis of the amount of tooth movement and alveolar bone volume was performed using computed microtomography. To investigate bone remodeling, a morphological study was performed using the hematoxylin-eosin (HE) method. The one-way ANOVA test was used for statistical analysis, followed by the Tukey test with a 95% confidence interval. Results: There were no statistically significant differences (p>0.05) between the control group and the experimental groups regarding the amount of tooth movement, alveolar bone volume, and bone remodeling of the rats subjected to orthodontic tooth movement. Conclusion: The findings of this study suggest that creatine does not affect orthodontic movement at the doses tested (AU).

ABSTRACT

O objetivo do estudo que deu origem a esta tese foi avaliar o impacto do uso de alinhadores ortodônticos na qualidade de vida relacionada à saúde bucal (QVRSB) dos indivíduos. O estudo foi realizado no Curso de Especialização em Ortodontia da Associação Brasileira de Odontologia (ABO). Adolescentes e adultos foram dispostos em dois grupos: Grupo 1 (G1) ­ indivíduos em uso de alinhadores ortodônticos; e Grupo 2 (G2) ­ indivíduos em uso de aparelho fixo convencional. Durante o tratamento ortodôntico, todos os participantes responderam ao questionário Oral Health Impact Profile (OHIP-14) para avaliação da QVRSB, que inclui sete subescalas: limitação funcional (LF), dor física (DF), desconforto psicológico (DP), incapacidade física (IF), incapacidade psicológica (IP), incapacidade social (IS) e incapacidade (I). Quanto maior o escore, mais negativa é a percepção da QVRSB. A má oclusão dos participantes foi avaliada utilizando o Índice de Estética Dental (IED). As variáveis sexo e idade dos participantes, renda familiar e tempo de tratamento ortodôntico também foram coletadas. No artigo 1, comparou-se o impacto do uso de alinhadores ortodônticos com o uso dos aparelhos fixos convencionais na QVRSB dos indivíduos. O G1 foi composto por 33 indivíduos em tratamento com alinhadores ortodônticos e o G2 foi composto por 28 indivíduos em tratamento com aparelho fixo convencional. Foram realizadas análises descritivas, teste Mann-Whitney e regressão de Poisson. O tamanho do efeito (TE) e a mínima diferença clinicamente importante (MDCI) também foram determinados. A média de idade dos participantes foi de 30,69 anos. Indivíduos do G1 apresentaram escore significativamente menor para DF e para o escore total em comparação aos do G2 (p<0,05). O TE para DF foi grande (TE=0,74) e para o escore total foi moderado (TE=0,46). O TE foi moderado para IF (TE=0,50). A diferença entre os grupos para a dimensão DF (1,30) e para a dimensão IF (0,90) foi maior que a MDCI (0,87 e 0,88, respectivamente). Os resultados da regressão de Poisson mostraram que indivíduos do G2 apresentaram o escore da dimensão DF 1,40 vezes maior do que os do G1 no modelo ajustado (OR=1,40, [1,03-1,90], p=0,03). Concluiu-se que usuários de alinhadores ortodônticos apresentam uma percepção mais positiva da QVRSB em comparação aos usuários de aparelho fixo. No artigo 2, explorou-se os fatores associados à QVRSB de usuários de alinhadores ortodônticos. Participaram 34 indivíduos. Foram realizadas análise descritiva e regressão de Poisson com variância robusta para avaliar os fatores que podem estar associados ao impacto do uso de alinhadores ortodônticos na QVRSB dos participantes. Foram determinados coeficientes beta (Coef.) e erros padrão (EP). Indivíduos com maior IED apresentaram pontuação significativamente maior nas subescalas LF [p=0,014, Coef. (EP)=0,12 (0,51)], DF [p=0,004, Coef. (EP)=0,08 (0,02)], IF [p=0,001, Coef. (EP)=0,21 (0,06)], IP [p=0,007, Coef. (EP)=0,15 (0,05)], IS [p=0,001, Coef. (EP)=0,21 (0,05)], e o escore total [p=0,001, Coef. (EP)=0,12 (0,02)]. Para a subescala I [p=0,011, Coef. (EP)=-0,07 (0,02)], indivíduos mais jovens obtiveram pontuação significativamente maior. Concluiu-se que indivíduos mais jovens e com má oclusão mais severa apresentaram pior QVRSB.


The aim of the study that gave rise to this thesis was to assess the impact of the wearing of orthodontic aligners on the oral health-related quality of life (OHRQoL) of individuals. Data collection was carried out at the Graduate Program in Orthodontics of the Associação Brasileira de Odontologia (ABO). Adolescents and adults were divided into two groups; Group 1 (G1): individuals wearing orthodontic aligners. Group 2 (G2): individuals wearing conventional fixed appliances. During orthodontic treatment, all participants answered the Oral Health Impact Profile (OHIP-14) with seven subscales: functional limitation (FL), physical pain (PP), psychological discomfort (PD), physical disability (PhyD), psychological disability (PsyD), social disability (SD), and handicap (H). The higher the score, the more negative was the erception of OHRQoL. Participants' malocclusion was evaluated using the Dental Aesthetics Index (DAI). The variables sex and age of participants, family income e time of orthodontic treatment were collected. Artigo 1: one aimed to compare the impact of the wearing of orthodontic aligners with the wearing of conventional fixed appliances on the OHRQoL of individuals. Group 1 (G1) consisted of 33 individuals undergoing treatment with orthodontic aligners and Group 2 (G2) comprised 28 individuals undergoing treatment with conventional fixed appliances. Descriptive statistics, Mann-Whitney test, and Poisson regression were performed. Effect size (ES) and minimal clinically important difference (MCID) were also determined. Participants' mean age was 30.69 years. Individuals in G1 had a significantly lower score for PP and for the total score compared to those in G2 (p<0.05). The TE for PP was high (TE=0.74) and moderate for the total score (TE=0.46). TE was moderate for PhyD (TE=0.50). The difference between groups for the PP subscale (1.30) and for the PhyD subscale (0.90) was greater than the MCID (0.87 and 0.88, respectively). The results of Poisson regression showed that individuals in G2 had a score on the PP subscale 1.40 times higher than those in G1 in the adjusted model (OR=1.40, [1.03-1.90], p=0,03). We conclude that wearers of orthodontic aligners have a more positive perception of OHRQoL compared to wearers of conventional fixed appliances. Article 2: one aimed to explore the factors associated with the OHRQoL of wearers of orthodontic aligners. Thirty-four individuals participated. One performed descriptive statistics and Poisson regression with robust variance to evaluate the factors that may be associated with the impact of the wearing of orthodontic aligners. On OHRQoL. Beta coefficients (coef) and standard errors (SE) were determined. Individuals with higher DAI had significantly higher scores in the subscales FL [p=0.014, Coef (SE)=0.12 (0.51)], PP [p= 0.004, Coef (SE)= 0.08 (0.02)], PhyD [p=0.001, Coef (SE)=0.21 (0.06)], PsyD [p=0.007, Coef (SE)=0.15 (0.05)], SD[p=0.001, Coef (SE)=0.21 (0.05) )], and the total score [p=0.001, Coef (SE)=0.12 (0.02)]. For the subscale H [p=0.011, Coef (SE)=-0.07 (0.02)], younger individuals scored significantly higher. One can conclude that younger individuals and those with a more severe malocclusion exhibited worse OHRQoL.

ABSTRACT

Até a presente data, encontramos poucos estudos que avaliaram satisfação com o tratamento ortodôntico e estes utilizaram questionários genéricos de satisfação, que podem não apresentar responsividade adequada para a avaliação de uma condição específica. Além disso, tais questionários não eram validados colocando em dúvida a confiabilidade dos estudos realizados. Desta forma, o presente estudo objetivou avaliar a satisfação de pais/cuidadores de indivíduos com idade entre 6 e 17 anos com relação ao tratamento ortodôntico recebido por seus (suas) filhos (as) utilizando um instrumento condição específica para este desfecho. O Comitê de Ética em Pesquisa com Seres Humanos da Universidade Federal de Minas Gerais aprovou este estudo (58735122.9.0000.5149). A amostra foi composta por 68 pais/cuidadores de crianças/adolescentes submetidos ao tratamento ortodôntico em clínicas com atendimento ortodôntico. Para serem incluídos, pais/cuidadores deveriam ser nativos em português. As crianças/adolescentes, para participarem do estudo, não deveriam apresentar anomalia craniofacial ou desordem cognitiva. Para avaliação de satisfação, um questionário validado no Brasil, composto por 25 questões distribuídas em 3 subescalas foi usado. A primeira subescala contém 13 itens para avaliação da satisfação com o processo do tratamento e a segunda subescala contém 7 itens que medem o efeito psicossocial do tratamento. Já a terceira subescala possui 5 itens avaliando o resultado geral do tratamento. Cada item tem 5 opções de resposta de acordo com a escala Likert variando de 1 a 5; 1=discordo totalmente, 2=discordo, 3=não concordo nem discordo, 4=concordo e 5=concordo totalmente. Quanto maior o escore, maior a satisfação do pai/responsável com o tratamento ortodôntico recebido pelo(a) seu(sua) filho(a). As seguintes variáveis também foram coletadas: sexo dos participantes, renda familiar, número de pessoas na família, escolaridade do responsável, tipo, tempo, e época de término do tratamento e gravidade da má oclusão. Análise estatística foi realizada com o programa Statistical Package for the Social Science (SPSS, versão 22,0, IBM Inc., Armonk, EUA). Análise descritiva foi feita para as variáveis sociodemográficas e clínicas da amostra. Quatro modelos de regressão de Poisson foram construídos para se avaliar os fatores associados à satisfação de pais/cuidadores com relação ao tratamento ortodôntico das(os) crianças/adolescentes. Os resultados foram fornecidos em razão das chances (RC) e intervalo de confiança (IC) em 95%. A média de idade foi de 12,84 (±2,96) anos. Pais/cuidadores de famílias com ≥4 pessoas apresentaram um escore de satisfação para a subescala procedimentos durante o tratamento menor do que pais/cuidadores de famílias com ≤3 pessoas (p=0,016). Pais/cuidadores de crianças/adolescentes que tinham sido submetidos ao tratamento corretivo apresentaram um escore de satisfação para as subescalas efeitos psicológicos do tratamento e resultados do tratamento e para o escore total do questionário maior do que pais/cuidadores de crianças/adolescentes que tinham sido submetidos ao tratamento interceptativo/corretivo (p<0,05). Pais/cuidadores de crianças/adolescentes com má oclusão mais grave também apresentavam um escore mais alto da subescala resultados do tratamento (p=0,010). Conclui-se que número de pessoas na família, tipo de tratamento e má oclusão são associados à satisfação de pais/cuidadores com relação ao tratamento ortodôntico recebido por crianças/adolescentes.


To date, few studies assessing satisfaction with orthodontic treatment have been found and these studies used generic satisfaction questionnaires, which may not be adequately responsive to the assessment of a specific condition. Furthermore, such questionnaires were not validated, posing doubts on the reliability of the studies carried out. Therefore, the present study aimed to evaluate the satisfaction of parents/caregivers of individuals aged between 6 and 17 years regarding the orthodontic treatment received by their children/adolescents using a specific condition instrument. The Human Research Ethics Committee of the Federal University of Minas Gerais approved this study (58735122.9.0000.5149). The sample consisted of 68 parents/caregivers of children/adolescents who had undergone orthodontic treatment in clinics offering orthodontic care. To be included, parents/caregivers should be native Portuguese speakers. Children/adolescents, to participate in the study, should not have craniofacial anomalies or cognitive disorders. To assess satisfaction, a questionnaire validated in Brazil, consisting of 25 questions distributed across 3 subscales, was used. The first subscale contains 13 items to assess satisfaction with the treatment process and the second subscale contains 7 items that measure the psychosocial effect of the treatment. The third subscale has 5 items evaluating the general result of the treatment. Each item has 5 response options according to the Likert scale ranging from 1 to 5; 1=totally disagree, 2=disagree, 3=neither agree nor disagree, 4=agree, and 5=totally agree. The higher the score, the greater the parent's/caregiver's satisfaction with the orthodontic treatment received by their child/adolescent. The following variables were also collected: sex of participants, family income, number of people in the family, education of the parent/ caregiver, type, time, and time of completion of treatment, and severity of the malocclusion. Statistical analysis was performed using the Statistical Package for the Social Science (SPSS, version 22.0, IBM Inc., Armonk, USA). Descriptive analysis was carried out for the sociodemographic and clinical variables of the sample. Four Poisson regression models were constructed to evaluate the factors associated with the satisfaction of parents/caregivers regarding the orthodontic treatment of children/adolescents. The results were provided as odds ratios (OR) and 95% confidence intervals (CI). The mean age was 12.84 (±2.96) years. Parents/caregivers from families with ≥4 people had a lower satisfaction score for the procedures during treatment subscale than parents/caregivers from families with ≤3 people (p<0.016). Parents/caregivers of children/adolescents who had undergone corrective treatment had a higher satisfaction score for the psychological effects of treatment and treatment results subscales and for the total score of the questionnaire than parents/caregivers of children/adolescents who had undergone interceptive/corrective treatment (p<0.05). Parents/caregivers of children/adolescents with more severe malocclusion also had a higher score on the treatment results subscale (p=0.010). One can conclude that the number of people in the family, type of treatment, and malocclusion are associated with the satisfaction of parents/caregivers regarding the orthodontic treatment received by children/adolescents.
