Research interest on dental sealant in dentistry based on the 100 most cited articles: bibliometric analysis

Abstract The aim of this study was to identify and analyze the characteristics of the 100 most cited articles about dental sealants (DS) in dentistry. In September 2023, a search was performed in the Web of Science Core Collection (WoS-CC) database. The following information was extracted from each article: number and density of citations, year of publication, authorship, journal, impact factor, keywords, study design, theme, continent, country, and institution. The citations of the WoS-CC were compared with those of the Scopus and Google Scholar databases. The VOSviewer software was used to generate collaborative networks. The number of citations ranged from 33 to 205. The articles were published between 1961 and 2016. Buonocore MG (7%) was the most prominent author among the most cited. The Journal of the American Dental Association was the most frequent journal (25%) and Journal of Dental Research (7.6) had the highest impact factor. Most studies had interventional (41%) and laboratory (31%) designs, mainly addressing DS effectiveness in the prevention and control of dental caries (86%). There was a predominance of publications from North America (46%) and the USA was the country with the highest number of articles (44%). The most frequent institutions were the Centers for Disease Control and Prevention (USA) and the University of Rochester (USA) (6% each). "Retention" was the most frequent keyword. In conclusion, the 100 most cited articles were mostly interventional and laboratory studies, addressing the retention and efficacy of DS. Most of the articles were concentrated in North America and Europe, demonstrating a little collaboration from other continents.

Persistent pain after successful endodontic treatment in a patient with Wegener's granulomatosis: a case report.

Wegener's granulomatosis (WG) is a condition with immune-mediated pathogenesis that can present oral manifestations. This report describes the case of a patient diagnosed with WG 14 years previously, who was affected by persistent pain of non-odontogenic origin after successful endodontic treatment. A 39-year-old woman with WG was diagnosed with pulp necrosis and apical periodontitis of teeth #31, #32, and #41, after evaluation through a clinical examination and cone-beam computed tomography (CBCT). At the first appointment, these teeth were subjected to conventional endodontic treatment. At 6- and 12-month follow-up visits, the patient complained of persistent pain associated with the endodontically treated teeth (mainly in tooth #31), despite complete remission of the periapical lesions shown by radiographic and CBCT exams proving the effectiveness of the endodontic treatments, thus indicating a probable diagnostic of persistent pain of non-odontogenic nature. After the surgical procedure was performed to curette the lesion and section 3 mm of the apical third of tooth #31, the histopathological analysis suggested that the painful condition was likely associated with the patient's systemic condition. Based on clinical, radiographic, and histopathological findings, this unusual case report suggests that WG may be related to non-odontogenic persistent pain after successful endodontic treatments.

The 100 most-cited papers in dentistry for individuals with neurodevelopmental disorders: Bibliometric profile of scientific research.

AIM: To conduct a bibliometric analysis of the top 100 most-cited papers in dentistry for individuals with neurodevelopmental disorders. METHODS AND RESULTS: A search strategy was constructed and conducted at the Web of Science in the category of "Dentistry, Oral Surgery, and Medicine". The following information was extracted from each paper: title, authorship, year of publication, title of the journal, study subject, study design, age range of sample participants, type of disability, institution, country and continent, number of citations and citation density. Google Scholar and Scopus were used to crosscheck the number of citations of the most-cited papers. The VOSviewer software was used to generate bibliometric network maps. The papers received 4453 citations in Web of Science, ranging from 30 to 106 citations. Most papers were published by the USA (35%), had an observational design (78%) and the main subject was epidemiology (31%). Most studies focused on individuals with Down syndrome (34%) and Autism Spectrum Disorder (18%) and were published in the Journal of Periodontology (10%) and the Pediatric Dentistry Journal (7%). CONCLUSION: Most of the studies included in this review were characterized as epidemiological studies. Future research should focus on behavior guidance, dental education, and access to dental services.

Children's and parents' perceptions concerning surgical attire: a systematic review / Percepções de crianças e pais sobre trajes médicos: uma revisão sistemática

ABSTRACT Objective: To review the literature about children's and parent's perceptions on surgical attire. Data source: A systematic search was conducted in the databases EMBASE, Latin American and Caribbean Health Sciences (LILACS), PubMed, PsycINFO, Scopus and Web of Science. Grey literature was searched on Google Scholar, Open Grey and ProQuest Dissertations, and Theses Database. Data synthesis: A total of 2,567 papers were identified. After a two-phase selection, 15 studies were included in narrative synthesis. Children favored wearing white coats in five of the nine included studies (55.5% [95%CI 48.3-62.7]; p=1.00). With respect to parents' preferences, results of vote counting showed that in 11 of 15 included studies, they favored physicians wearing white coats (73.3% [95%CI 67.9-78.6]; p=0.11). Conclusions: Children and parents have preferred physicians to wear a white coat with a very low certainty of evidence.

Em 11 dos 15 estudos incluídos, os pais tinham preferência pelos médicos que utilizavam jaleco (73,3% [IC95% 67,9-78,6]; p=0,11). Conclusões: Com uma qualidade baixa de evidência, crianças e pais preferem os médicos que usam jaleco branco.

Influence of the method for determining working length on the obturation level of primary molars

Abstract Efficient working length determination is essential for a successful endodontic treatment. The purpose of the present study was to evaluate whether the method for determining the working length of root canals (radiographic or electronic) influences the obturation level of primary molars. Thus, a controlled, triple-blind, randomized clinical trial was conducted. Sixty-four children aged 6 to 9 years with an indication for primary molar pulpectomy were included. Participants were divided into two groups according to the method used to determine the working length of the root canals: (G1) radiographic and (G2) using an electronic apex locator. The study had 3 operators: #1 performed the clinical procedures, except the electronic measurement; #2 performed radiographic measurement and final evaluation of obturation level; and #3 performed eligibility criteria and electronic measurement. Adequacy of obturation level was evaluated based on the final conventional radiography and it was recorded as acceptable or unacceptable (short or overfilled). Data were analyzed with repeated measures logistic regression. There was no difference between the obturation level of primary molars measured by radiographic and electronic methods (p > 0.05). The other investigated variables (age, tooth type, dental arch position, last instrumentation file, and canal location) also did not influence the obturation level (p > 0.05). In conclusion, both measurement methods resulted in similar adequacy of obturation level in primary molars after pulpectomy.

Parental acceptance toward behavior guidance techniques for pediatric dental visits: a meta-analysis

Abstract This study aimed to answer the following question: What is the proportion of acceptance reported by parents toward pediatric behavior guidance techniques (BGTs)? Observational studies that evaluated parental acceptance of BGTs during pediatric dental visits among parents of non-special health care need (non-SHCN) and SHCN children were included. A search of the Cochrane Library, Latin American and Caribbean Health Sciences (LILACS), MedLine/PubMed, PsycINFO, Scopus, and Web of Science databases, in addition to gray literature, was performed until October 2021. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment. The certainty of evidence was assessed using the Recommendation, Assessment, Development, and Evaluation (Grade). Fifty-three studies with 4868 participants were included, and 42 were retained for the random-effects proportion meta-analysis. The methodological quality varied from low to high. The agreement with the BGTs varied from 85.6% (95%CI: 77.5-92.1; p < 0.001; I 2 = 93.6%; 16 studies; n = 1399) for tell-show-do to 25.7% (95%CI: 17.8-34.4; p < 0.001; I 2 = 90.4%; 12 studies; n = 1129) for passive protective stabilization among non-SHCN children's parents; meanwhile, among the parents of SHCN children, it varied from 89.1% (95%CI: 56.1-99.7; p < 0.001; I 2 = 95.7%; 3 studies; n = 454) for tell-show-do to 29.1% (95%CI: 11.8-50.0; p = 0.001; I 2 = 84.8%; 3 studies; n = 263) for general anesthesia. The effect estimates varied greatly, as substantial heterogeneity across studies was observed, thus limiting the confidence in the results. Parents were more likely to agree with basic BGTs over advanced BGTs, with very low certainty of evidence. Dentists should discuss BGT options with parents. Protocol registration: PROSPERO CRD42018103834.

Endodontic therapy in primary teeth: a bibliometric analysis of the 100 most-cited papers

Abstract: The purpose of this review was to identify and analyze the main characteristics of the 100 most-cited papers in the field of endodontic therapy in primary teeth. A search for the most-cited articles was conducted in the Clarivate Analytics Web of Science 'Core-Collection' (WoS-CC) database up to December 2020. Papers were ranked in descending order, by number of citations, and each paper was matched with the citation count on Scopus and Google Scholar. Two independent reviewers selected the most-cited papers and analyzed it according to the number and density of citations, year and journal of publication, authors, countries and contributing institutions, study design, topic of the paper, and keywords. Spearman's correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The citation count varied from 15 to 135 (WoS-CC), 8 to 141 (Scopus), and 14 to 317 (Google Scholar). Of the 306 contributing authors, most paper contributions were from Sakai VT, Oliveira TM, and Machado MAAM (5 each). Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and "pulpotomy" was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.

Influência do banda-alça na manutenção de espaço do arco inferior após a perda precoce de molares decíduos: um estudo piloto / Influence of loop band on mandibular arch space maintenance after early loss of deciduous molars: a pilot study

Objetivo: Avaliar a influência do dispositivo banda-alça na perda de espaço após exodontia precoce de molares decíduos inferiores em escolares, em um período de 3 meses. Materiais e métodos: Trata-se de um estudo piloto de ensaio clínico randomizado, com dois grupos paralelos. A amostra incluiu 25 crianças, entre 6 e 9 anos, com indicação clínica e radiográfica de exodontia unilateral de um molar decíduo inferior. Estes foram divididos em Grupo Controle (G1): sem intervenção; e Grupo Intervenção (G2): com instalação de banda-alça. Todos os pacientes foram moldados antes do procedimento de exodontia (T1) e no acompanhamento de 3 meses (T2). Um avaliador cego quanto aos grupos e tempo realizou as medidas estabelecidas nos modelos de gesso. A análise estatística foi realizada por meio dos testes T pareado e T de Student nos casos de distribuição normal dos dados e testes não-paramétricos Wilcoxon e Mann-Whitney para distribuição não normal. Resultados: Todos os participantes foram classificados como Classe I, com overjet de até 3mm e padrão facial mesocéfalo. A maioria (64%) teve o segundo molar decíduo perdido. Após 3 meses, o G1 perdeu, em média, 0,75mm a mais na distância linear do espaço de extração comparado ao G2 (P<0,05). Conclusão: Concluiu-se que, embora os dois grupos apresentaram perda de espaço, o G1 (sem intervenção) apresentou uma perda de espaço maior no período de acompanhamento de 3 meses.

Objective: To evaluate the influence of the band and loop space maintainer on space loss after the early extraction of mandibular primary molars in schoolchildren, over a period of 3 months. Materials and Methods: a pilot study of a randomized clinical trial was carried out, with two parallel groups. The sample included 25 children, aged between 6 and 9 years, with clinical and radiographic indication for unilateral extraction of a mandibular primary molar. The patients were divided into Control Group (G1): with no intervention; and Intervention Group (G2): with the installation of the space maintainer. A dental cast was obtained before the extraction procedure (T1) and at the 3-month followup (T2). An evaluator, blinded to the groups and time, performed the established measures in the dental casts. Statistical analysis was performed using Paired Sample T test and Student's T test in cases of normal data distribution, and nonparametric Wilcoxon and Mann-Whitney tests for non-normal distribution. Results: All participants were classified as Class I, with an overjet of up to 3 mm and a mesocephalic facial pattern. The majority (64%) had a lost second deciduous molar. After 3 months, the G1 lost, on average, 0.75mm more in the linear distance from the extraction space (P<0.05). Conclusion: It was concluded that, although the two groups showed space loss, G1 (without intervention) showed a greater loss of space in the 3-month follow-up period.

The perception of caregivers of poor oral health of their children and its related clinical conditions / Percepção de cuidadores sobre a má saúde bucal das crianças e sua relação com condições clínicas

ABSTRACT Objective: To determine the association between the perception of caregivers regarding the oral health of their children and socio-demographic characteristics, report of dental pain, and clinical oral conditions. Methods: A cross-sectional study was conducted with 570 children aged two to five years old, enrolled at public preschools, and with their caregivers. Data regarding perceptions of oral health status in children, socio-demographic characteristics, and dental pain were collected from a questionnaire. Three examiners (Kappa>0.7) evaluated children's oral health status using the dmft index, pufa index, and the Andreasen classification for traumatic dental injury (TDI). The occurrence of open bite and overjet was also investigated. Descriptive analyses, and unadjusted and adjusted logistic regression were used, considering a 5% significance level. Results: A total of 24.7% of children had poor oral health status, which increased 4.92-fold (95% confidence interval [95%CI] 3.05-7.93) when children had dental caries, and 3.78-fold (95%CI 1.63-8.76) when there were consequences from dental caries. The perception of poor oral health was also associated to open bite (Odds Ratio [OR] 1.98; 95%CI 1.16-3.38) and TDI (OR 1.68; 95%CI 1.06-2.68). No associations were found between the perception of caregivers and socio-demographic variables or overjet. Conclusions: The perception of caregivers of poor oral health in their children was associated to dental caries, its consequences, TDI, and open bite.

RESUMO Objetivo: Determinar a associação entre a percepção dos cuidadores sobre a saúde bucal das crianças e características sociodemográficas, relato de dor dentária e condições clínicas bucais. Métodos: Foi realizado um estudo transversal com 570 crianças de dois a cinco anos matriculadas em pré-escolas públicas e seus cuidadores. Os dados referentes à percepção do estado de saúde bucal nas crianças, características sociodemográficas e dor dentária foram coletados por meio de um questionário. Três examinadores (Kappa>0,7) avaliaram o estado de saúde bucal das crianças usando o índice ceo-d, o índice PUFA e a classificação de Andreasen para traumatismo dentário (TD). A ocorrência de mordida aberta e overjet também foi investigada. Análise descritiva e regressão logística não ajustada e ajustada foram realizadas, considerando um nível de significância de 5%. Resultados: A percepção da má condição de saúde bucal nas crianças foi de 24,7%, a qual aumentou 4,92 vezes (IC95% ­3,05-7,93) quando as crianças apresentaram cárie dentária e 3,78 vezes (intervalo de confiança de 95% [IC95%] 1,63-8,76) quando houve consequências de cárie dentária. A percepção de saúde bucal ruim também foi associada a mordida aberta (Odds Ratio [OR] 1,98; IC95% 1,16-3,38) e TD (OR 1,68; IC95% 1,06-2,68). Não foram encontradas associações entre as percepções dos cuidadores e variáveis sociodemográficas ou overjet. Conclusões: As percepções dos cuidadores sobre a má condição de saúde bucal das crianças foram associadas à cárie dentária, suas consequências, TD e mordida aberta.

Is the perception of anxiety in dental care by children and their parents concordant? / A percepção da ansiedade no atendimento odontológico pelas crianças e por seus pais são concordantes?

ABSTRACT Objectives: This research evaluated the caregivers' perception on dental anxiety of their children and verified its association with independent variables: caregivers' dental anxiety and the reason for their last dental appointment, socioeconomic factors, caregivers and children's last dental visit, children's oral health status, dental anxiety and kind of dental appointment. Methods: Fifty-eight children aged 6 to 9 years old and their caregivers participated in the study. For this cross-sectional study the participants were selected from a clinical study where half of the children received fluortherapy and the other half tooth extraction. The caregivers answered questions about socioeconomic status and to evaluate their dental anxiety and the perception on children's dental anxiety they answered the Dental Anxiety Scale and Dental Anxiety Question, respectively. To evaluate children's dental anxiety the Modified Venham Picture Test was applied and their oral health status was verified with the DMFT index. Data were analyzed with Chi-square, Fisher's Exact and Mann-Whitney's test. Results: The frequency of the caregivers' perception on dental anxiety of their children were 50.9%. However, 41.4% of children reported dental anxiety. There was a significant difference between Dental Anxiety Question and Modified Venham Picture Test (p=0.002). There was no relationship between caregivers' perception on dental anxiety of their children and other independent variables. Conclusion: There was a significant difference between children's dental anxiety and the perception of it by those caregivers.

RESUMO Objetivos: Este trabalho avaliou a percepção dos responsáveis sobre a ansiedade odontológica das crianças e sua associação com as variáveis independentes: ansiedade odontológica dos responsáveis e o motivo para sua última consulta odontológica, fatores socioeconômicos, última visita ao dentista dos responsáveis e da criança, condição bucal da criança e tipo de procedimento odontológico realizado na consulta. Métodos: Neste estudo transversal a amostra contou com 58 crianças entre 6 e 9 anos e seus responsáveis. Os participantes foram selecionados a partir de um estudo clínico em que metade das crianças receberam fluorterapia e as outras exodontia. Os responsáveis responderam ao questionário socioeconômico e para avaliar a ansiedade odontológica e a percepção sobre a ansiedade odontológica das crianças eles responderam a Dental Anxiety Scale e a Dental Anxiety Question, respectivamente. Para avaliar a ansiedade odontológica das crianças foi aplicado o Venham Picture Test Modificado e a sua condição bucal foi verificada pelo índice CPO-D/ceo-d. A análise dos dados foi realizada pelo teste Qui-quadrado, Exato de Fisher e Mann-Whitney. Resultados: A frequência de responsáveis que perceberam a ansiedade odontológica das crianças foi de 50,9%. Entretanto, 41,4% das crianças relataram a ansiedade odontológica. Houve uma diferença significativa entre o Dental Anxiety Question e o Venham Picture Test Modificado (p = 0,002). Não houve relação entre a percepção dos responsáveis sobre a ansiedade odontológica das crianças com as demais variáveis independentes. Conclusão: Existiu uma diferença significativa entre a ansiedade odontológica das crianças e a percepção desta pelos responsáveis.

Associação entre problemas para dormir e condições orais em escolares / Association between trouble sleeping and oral conditions among schoolchildren

ABSTRACT Objective: To investigate the prevalence of self-reported trouble sleeping due to dental problems and its association with oral conditions in schoolchildren. Methods: This is a cross-sectional study carried out with a representative sample of 1,589 schoolchildren aged 8-10 years enrolled in public schools from Florianópolis, Santa Catarina, Brazil. Non-clinical data included a questionnaire about socioeconomic indicators answered by parents/guardians. Children were questioned about whether they had trouble sleeping due to dental problems and about previous history of toothache. Clinical oral examinations were performed to evaluate dental caries - Decayed, Missing, and Filled Teeth Index (DMFT/dmft index) and its clinical consequences [PUFA/pufa index: considering the presence of pulpal involvement (P/p); ulceration of tissues due to tooth fragments from decayed crowns (U/u); fistula (F/f); and abscesses (A/a), and traumatic dental injuries (TDI)]. We conducted a descriptive analysis and used adjusted logistic regression models (p<0.05; 95%CI). Results: The prevalence of trouble sleeping due to dental problems was 28%. Children with untreated dental caries (OR 1.32; 95%CI 1.05-1.67) and clinical consequences from the PUFA/pufa index (OR 1.89; 95%CI 1.45-2.46) had higher chances of reporting trouble sleeping due to dental problems. Conclusions: Approximately one-third of the children declared having trouble sleeping due to dental problems. Untreated dental caries and its clinical consequences were associated with self-reported trouble sleeping due to dental problems in schoolchildren.

RESUMO Objetivo: Investigar a prevalência de problemas para dormir por motivos dentários autorrelatado e sua associação com condições orais adversas em escolares. Métodos: Estudo transversal com amostra representativa de 1589 escolares de 8 a 10 anos matriculados em escolas públicas de Florianópolis, Brasil. Os dados não clínicos incluíram um questionário sobre indicadores socioeconômicos respondidos pelos pais/cuidadores. As crianças foram questionadas se tinham problemas para dormir por motivos dentários e sobre episódios anteriores de dor de dente. Foram realizados exames clínicos orais para avaliar: cárie dentária - Índice de Dentes Cariados, Perdidos e Obturados (índice CPO-D/ceo-d) - e suas consequências clínicas (índice PUFA/pufa - presença de envolvimento pulpar (P/p); ulceração (U/u); fístula (F/f); e abscessos (A/a) e traumatismo dental (TD). Foram realizados análise descritiva e modelos ajustados de regressão logística (p<0,05; IC95%). Resultados: A prevalência de problemas para dormir por motivos dentários foi de 28%. Crianças com cárie dentária não tratada (OR 1,32; IC95% 1,05-1,67) e presença de índice PUFA/pufa (OR 1,89; IC95% 1,45-2,46) apresentaram maiores chances de relatar problemas para dormir devido a razões dentárias. Conclusões: Aproximadamente, um terço das crianças apresentou problemas para dormir devido a razões dentárias. Cárie dentária não tratada e suas consequências clínicas foram associadas a problemas autorrelatados para dormir por motivos dentários em escolares.

Socioeconomic Disparities in Oral Health Related Quality of Life of Schoolchildren: A Cross-Sectional Study

Abstract Objective: To analyze whether demographic and socioeconomic factors can influence the OHRQoL in schoolchildren. Material and Methods: A cross-sectional study using a representative sample of 1137 children aged 8-10 years, enrolled in public schools in Florianópolis, Brazil, was conducted. Children answered the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) quality of life questionnaire and their parents responded to socioeconomic and demographic questions. Logistic regression models were used to analyze the data. Results: Higher probability of presenting a negative impact on the OHRQoL was observed in children whose skin color was non-white (OR 1.46, 95% CI 1.04-1.69) and female (OR 1.33, 95% CI 1.04-1.69). Children in whom the head of the family had years of schooling 9-11 (p=0.001), 5-8 (p=0.005) and ≤4 (p=0.000) were more likely to have a negative impact on the OHRQoL. CPQ8-10 domains evaluation showed that variables education, gender, skin color, and age were associated with a negative impact on OHRQoL (p≤0.05). Conclusion: The educational level of the head of the family and the demographic characteristics of the children are associated with a negative impact on the OHRQoL.

Is there an association between crown discoloration and pulp necrosis in traumatized permanent teeth? A meta-analysis

Abstract The present study aimed to identify the scientific evidence regarding the association between crown discoloration and pulp necrosis in traumatized permanent teeth. A systematic literature search was conducted in the PubMed/Medline, Lilacs/BBO, Scopus, Web of Science, Cochrane Library databases, and grey literature. Quality assessment and bias control were carried out according to the Fowkes and Fulton guidelines. Meta-analysis was performed, and the odds ratio was calculated with a 95% confidence interval. The quality assessment of the evidence was determined for the meta-analysis outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. From 2,702 studies identified, five articles met the inclusion criteria. One among these showed no methodological soundness and was excluded from the meta-analysis, and the remaining four studies were included in the meta-analysis. The total number of traumatized permanent teeth evaluated in the meta-analysis was 367. The results showed a positive association between crown discoloration and pulp necrosis in permanent teeth. Teeth with crown discoloration showed 23 times more chance to present pulp necrosis than teeth without crown discoloration (OR 23.82 [1.25, 452.87]; p = 0.03), with a very low certainty of evidence. There is a significant association between crown discoloration and pulp necrosis of traumatized permanent teeth. Due to the very low strength of evidence according to GRADE, this result should be viewed with caution.

Avaliação do comportamento odontológico infantil durante procedimentos de profilaxia e exodontia / Evaluation of children's dental behavior during prophylaxis and extraction procedures

Objetivo: Avaliar o comportamento infantil durante os tratamentos odontológicos de profilaxia e de exodontia. Métodos: Este estudo transversal contou com 58 crianças, entre 6 e 9 anos de idade. Dentre essas, 29 crianças foram submetidas ao procedimento de exodontia e 29 ao procedimento de profilaxia. O comportamento infantil frente ao tratamento odontológico proposto foi avaliado por um cirurgião-dentista treinado através da versão brasileira e validada da Escala Comportamental de Venham (Venham's Behavior Rating Scale (BvVBRS). Avaliou-se também a ansiedade infantil prévia ao tratamento odontológico através da Venham Picture Test modificada (VPTm). A condição bucal foi avaliada pelo índice CPO-D e ceo-d, por pesquisador previamente calibrado (Kappa > 0,7). Os pais/responsáveis responderam a um questionário socioeconômico e questões relacionadas a experiência odontológica prévia das crianças. Realizou-se análise descritiva e teste Qui-quadrado com nível de significância de 5%. Resultados: Em relação ao comportamento o grupo submetido à profilaxia apresentou 100% das crianças com um comportamento positivo, enquanto no grupo submetido à exodontia houve 75,9% das crianças com comportamento positivo (p = 0,010). Idade, gênero e presença de ansiedade prévia aos procedimentos não tiveram relação estatisticamente significante com o comportamento infantil. A presença de cárie na dentição decídua esteve associada ao comportamento negativo durante os procedimentos odontológicos (p = 0,013). Conclusão: Foi observado que durante o procedimento de profilaxia os pacientes demonstraram um comportamento mais colaborador quando comparado ao procedimento de exodontia.

Aim:To investigate the behavior of children during dental treatments of prophylaxis and dental extraction. Methods: Fifty-eight children, 6 to 9 years of age, and their caregivers participated of this cross-sectional study. Of these, 29 children underwent prophylaxis and 29 dental extraction. Child behavior was assessed through the Brazilian version of the Venham's Behavior Rating Scale (BvVBRS), and dental anxiety was measured by the Venham Picture Test modified (VPTm). Clinical examination was performed by a calibrated examiner (Kappa > 0.7), using the decay, missing, filled index for primary and permanent dentition dmft/DMFT index. The caregivers answered a socioeconomic questionnaire and questions related to the previous dental experience of the children. Descriptive data analysis and Chi-square test were performed, with a significance level of 5%. Results:Regarding behavior, the prophylaxis group presented 100% of children with a positive behavior, while the extraction group contained 75.9% of children with positive behavior, and this difference was statistically significant (p = 0.010). Age, gender, and presence of anxiety prior to the procedures had no statistically significant relationship to the presented child behavior. The presence of caries in the deciduous dentition was associated with child behavior during dental procedures (p = 0.013). Conclusion: It was observed that the type of procedure interfered directly in the negative behavior of the children, with a difference in cooperation with invasive (dental extraction) and non-invasive (prophylaxis) procedures.

Association of gender, oral habits, and poor sleep quality with possible sleep bruxism in schoolchildren

Abstract The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents' perception of children's behavior, and children's oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regression were performed and the level of significance was set at 5%. A total of 1,554 parents of children aged 8 to 10 years participated in this study. Possible sleep bruxism was reported as mild for 65.7%, moderate for 25.3%, and severe for 9% of the children. In the adjusted multinomial logistic regression, boys were 79% more likely to have sleep bruxism (OR: 1.79; 95%CI 1.23-2.60) and were 2.06 more times at risk of being in the habit of lip biting (OR: 2.06; 95%CI 1.26-3.37). Children with possible severe sleep bruxism were 61% more likely to develop object biting (OR: 1.61; 95%CI 1.09-2.39), 52% more likely to have headaches (OR: 1.52; 95%CI 1.01-2.28), and 3.29 more times at risk of poor sleep quality (OR: 3.29; 95%CI 2.25-4.82). Based on the report, boys with lip and object biting habits, headaches, and poor sleep quality presented a higher chance of possible severe sleep bruxism.

Malocclusion traits and sucking habits in preschool children: a cross-sectional study

Objective: The aim was to evaluate the prevalence of malocclusion traits altogether and separate in anterior open bite, accentuated overjet and posterior cross-bite, and the possible association between them and sucking habits and breastfeeding. Methods : A preschool-based cross-sectional study was conducted with 472 children aged 24-60 months and their parents (response rate 86.6%). Three trained dentists (Kappa > 0.70) examine children for anterior open bite, accentuated overjet and posterior cross-bite and parents answered a questionnaire indicating the presence of breastfeeding, bottle usage, pacifier usage, finger sucking and the length of usage of all these habits. Results : The prevalence of malocclusion traits was 38.8%, Accentuated overjet was the most prevalent (30.3%) followed by posterior cross-bite (8.9%) and anterior open bite (7.4%). The unadjusted Poisson regression showed that children who were not breastfed had 63.0% more prevalent malocclusion traits when compared with those who were breastfed (RP 1.63, 95%CI 1.06-2.50). Length of pacifier usage in months was the only habit remained in the adjusted model associated with anterior open bite (RP 1.10, 95%CI 1.05-1.14, p < 0.000) and accentuated overjet (RP 1.03, 95%CI 1.01- .05, p = 0.004). For posterior cross-bite none habit showed association in the adjusted model. All models were adjusted for age and sex. Conclusion : Accentuated overjet is the most prevalent malocclusion trait. Length of pacifier usage is associated with the presence of malocclusion traits, anterior open bite and accentuated overjet. None of the investigated habits is associated with posterior cross-bite.

Objetivo: O objetivo foi estimar a prevalência de maloclusões avaliadas em conjunto e separadamente em mordida aberta anterior, sobressaliência acentuada e mordida cruzada posterior, e a possível associação entre elas e os hábitos de sucção e amamentação. Métodos : Estudo transversal foi realizado com 472 pré- escolares de 24 a 60 meses e seus pais (taxa de resposta de 86,6%). Três dentistas treinados (Kappa > 0,70) examinaram as crianças para mordida aberta anterior, sobressaliência acentuada e mordida cruzada posterior e os pais responderam a um questionário indicando a presença de amamentação, uso de mamadeira, uso de chupeta, sucção de dedo e tempo de hábito. Resultados : A prevalência de maloclusões foi de 38,8%. A sobressaliência acentuada foi o mais prevalente (30,3%), seguido da mordida cruzada posterior (8,9%) e da mordida aberta anterior (7,4%). A regressão de Poisson não ajustada mostrou que as crianças que não foram amamentadas apresentaram 63,0% maior prevalência de maloclusão quando comparadas com aquelas que foram amamentadas (RP 1,63, IC95% 1,06-2,50). A duração do uso de chupeta em meses foi o único hábito que permaneceu no modelo ajustado associado à mordida aberta anterior (RP 1,10, IC 95% 1,05-1,14, p < 0,000) e sobressaliência acentuada (RP 1,03, IC 95% 1,01- 1,05, p = 0,004). Para mordida cruzada posterior nenhum hábito mostrou associação no modelo ajustado. Todos os modelos foram ajustados por idade e sexo. Conclusão : A sobressaliência acentuada é a maloclusão mais prevalente. O tempo do uso de chupeta está associado à presença de maloclusão, mordida aberta anterior e sobressaliência acentuada. Nenhum dos hábitos investigados está associado à mordida cruzada posterior.

Mouth Breathing and Prevalence of Sleep Bruxism among Preschoolers aged 2 to 5 years

Objective: To determine the prevalence of bruxism, associating it with mouth breathing in preschool children in Florianopolis, Brazil. Material and Methods: Clinical examination and questions to parents/guardians of 429 children aged 2-5 were conducted. The clinical examination was performed by three calibrated examiners to register the presence of tooth wear on incisors and molars. The questions were related to sleep bruxism (teeth grinding) and mouth breathing. For determinate diagnosis, were "possible" bruxism by the American Academy of Sleep Medicine and "probable" bruxism, whereas the Item Response Theory was employed for mouth breathing. To determine the associations, a Chi-square test and Fisher exact test with a standard error of 5% and 95% interval confidence were applied. Results: The clinical examination revealed bruxism in 8.2%, whereas the parental report revealed bruxism in 17.2%. When clinical examination was associated with the parent's report, bruxism was present in 2.1%. Among the non-clinical variables, the most prevalent changes included: child presenting a regular stuffy nose (19.6%), followed by child is always open-mouthed (16.1%). A significant statistical association between bruxism and age was obtained (p<0.05), the age group with prevalence of 4 and 5 years old with 68.9%. There was no mouth breathing association with the presence of bruxism (p>0.05). Conclusion: Bruxism was prevalent for children aged 4-5 and bruxism had no association with mouth breathing.

O impacto do traumatismo dental e do comprometimento estético na qualidade de vida de pré-escolares / Impact of dental trauma and esthetic impairment on the quality of life of preschool children

RESUMO Objetivo: Avaliar o impacto do trauma dental (TD) e do comprometimento estético na qualidade de vida (QV) de pré-escolares e familiares. Métodos: Este estudo foi realizado com crianças de 2 a 5 anos em 11 pré-escolas de Florianópolis (SC), Brasil. Os pais/responsáveis preencheram a versão brasileira do questionário sobre QV Early Childhood Oral Health Impact Scales (B-ECOHIS), um questionário socioeconômico e perguntas específicas sobre TD. As crianças foram examinadas por três examinadores calibrados (kappa>0,7). O TD foi avaliado de acordo com os índices adotados pela Organização Mundial de Saúde (OMS), e o comprometimento estético também foi classificado. Os dados foram analisados descritivamente e submetidos à análise bivariada por qui-quadrado e teste de Fisher, sendo significante p<0,05. Resultados: Dos pré-escolares examinados, 62,5% foram diagnosticados com trauma e 15,6% com comprometimento estético, e somente 12% dos pais relatou que seus filhos apresentam impacto na QV. O TD não se associou a sexo, idade ou QV. A alteração de cor da coroa por TD relacionou-se ao comprometimento estético, e apenas este causou impacto negativo na QV (p<0,05) e se associou ao domínio limitações orais (p<0,05). Conclusões: O comprometimento estético causou impacto negativo na QV das crianças, e o trauma dental não se associou com a QV das crianças nem de suas famílias.

ABSTRACT Objective: To evaluate the impact of dental trauma and impaired esthetics on the quality of life (QoL) of preschool children and their relatives. Methods: Study conducted with 192 children aged 2 to 5 years in 11 preschools in Florianópolis, Santa Catarina, South of Brazil. Parents/caregivers completed a questionnaire on quality of life (Brazilian version of the Early Childhood Oral Health Impact Scales - B-ECOHIS), a socioeconomic survey, and then answered specific questions related to dental trauma. The subjects were examined by three accordant examiners (Kappa>0.7). Dental trauma was evaluated on the basis of indexes adopted by the World Health Organization, and esthetic impairment was then classified. Data were descriptively analyzed and put to bivariate analysis by chi-square and Fisher tests, with significance level at 5%. Results: The prevalence of dental trauma was 62.5% with 15.6% of esthetic impairment. Almost 12% of parents reported impact on the quality of life of their children. Dental trauma was not significantly associated with gender, age or QoL. Crown color change by trauma was associated with esthetic impairment. Also esthetic impairment had a negative impact on QoL (p<0.05) and was associated with oral limitations (p<0.05). Conclusions: Esthetic impairment had a negative impact on children's quality of life, while dental trauma was not associated to it.

Implant-supported Oral Rehabilitation in Child with Ectodermal Dysplasia - 4-year Follow-up.

Ectodermal dysplasia (ED) is an anomaly determined by genetic factors that alter ectodermal structures such as skin, hair, nails, glands, and teeth. Children affected by this condition require extensive, comprehensive, and multidisciplinary treatment. An 8-year-old female patient visited the Dentistry Clinic of the Federal University of Santa Catarina with the chief complaint of multiple missing teeth. The mother reported that the patient had ED. Clinical and radiographic examination revealed the congenital absence of several primary and permanent teeth and tooth germs. Subsequent oral rehabilitation comprised the application of a maxillary denture and mandibular implant-supported fixed prosthesis. The child was also supplied with a wig for further enhancement of esthetics aimed at improving her emotional wellbeing. Psychological follow-up and speech therapy were also provided. After 4 years of follow-up, implant-supported oral rehabilitation has proved to be a satisfactory treatment option, allowing restoration of masticatory, phonetic, and esthetic function, as well as an improvement in the patient's self-esteem and social wellbeing.
