Estudo transversal foi realizado em um censo de 633 escolares de 12 anos de idade matriculados em escolas p?blicas e privadas da zona urbana da cidade de Diamantina, Minas Gerais. Dados foram coletados por meio de exame cl?nico e pela utiliza??o de question?rios autoaplic?veis. Foi adotada a renda familiar, escolaridade materna para avalia??o da condi??o socioecon?mica; o QCS-AE (Question?rio de Capital Social para Adolescentes Escolares) para medir o capital social e o AUDIT-C (Teste para Identifica??o de Problemas Relacionados ao Uso do ?lcool) para mensurar o consumo em binge de bebida alco?lica. Previamente foi realizado o treinamento e a calibra??o para o diagn?stico do traumatismo dent?rio adotando-se a classifica??o de Andreasen et al. As vari?veis cl?nicas overjet e tipo de prote??o labial foram avaliadas atrav?s de exame. Para obten??o dos resultados foram realizadas an?lise de frequ?ncia e teste de associa??o. As associa??es foram testadas pelo teste qui-quadrado, teste exato de Fisher (p < 0,05) e regress?o log?stica m?ltipla. A preval?ncia de traumatismo dent?rio foi 29,9% e do consumo em binge de bebida alco?lica 22,6%. O traumatismo dent?rio foi mais prevalente entre os adolescentes do sexo masculino (p = 0,010) com overjet acima de 5mm (p < 0,001)e prote??o labial inadequada (p < 0,001). Na an?lise univariada o capital social total (p = 0,039) e a confian?a (p = 0,014) estiveram associados ao traumatismo dent?rio. Os resultados da regress?o log?stica revelaram que o overjet acentuado, a prote??o labial inadequada e o consumo em binge de bebida alco?lica se mantiveram associados ao traumatismo dent?rio [RR = 3,80 (95% IC: 2,13-6,46) p < 0,0001], [RR = 5,58 (95% IC: 3,65-8,53) p < 0,0001] e [RR = 1,928 (95% IC: 1,213-3,063) p = 0,005]. A ado??o de um instrumento especialmente desenvolvido e validado para adolescentes escolares possibilitou a identifica??o dos dom?nios do capital social. A preval?ncia de traumatismo dent?rio aos 12 anos foi elevada e n?o houve associa??o estat?stica com o capital social.

A cross-sectional study was carried out involving 633 enrolled in public and private schools in urban areas of city Diamantina, Minas Gerais. Data were collected through a clinical examination and self-administered questionnaires. Socioeconomic data were collected using a questionnaire addressing household income and mother?s schooling, as well as the SCQ-AS (Social Capital Questionnaire for Adolescents Students) to measure social capital and the AUDIT-C (Alcohol Use Disorders Identification Test ? Consumption) to measure the binge in drinking. The classification proposed by Andreasen et al. was used for the determination of traumatic dental injuries. The clinical variables (overjet, lip protection) were determined through a clinical exam performed by an examiner who had undergone a training and calibration exercise. To obtain the results tests of frequency analysis and association were performed. Associations were tested using the chi-square, Fisher exact test (p < 0.05) and multiple logistic regression. The prevalence of dental trauma was 29.9% and the binge in drinking 22.6%. Dental trauma was more prevalent among males (p = 0,010), and those with accentuated overjet (p < 0.001) and with inadequate lip protection (p < 0.001). In univariate analysis, the total social capital (p = 0.039) and confidence (p = 0.014) were associated with dental trauma. The results of multiple logistic regression showed that the accentuated overjet, inadequate lip coverage and binge in drinking remained associated with traumatic dental injuries [RR = 3.80 (95% IC: 2.23-6,46) p < 0.0001], [RR = 5.58 (95% IC: 3.65-8.53) p < 0.0001] e [RR = 1.928 (95% IC: 1.213-3.063) p = 0.005]. The adoption of an instrument specifically developed and validated for schoolchildren 12-year-old allowed to identify several areas of the capital. The prevalence of traumatic dental injury (TDI) was high among the 12-year-old students analyzed. No significant associations were found between traumatic dental injury and socioeconomic status or social capital. Male students with accentuated overjet, inadequate lip coverage and binge in drinking had almost twice as more likely to be affected by traumatic dental trauma.

Pesquisa do estado de Minas Gerais (FAPEMIG) / Caracter?sticas oclusais est?o associadas ? ocorr?ncia de traumatismo dent?rio em pr?-escolares. Sobressali?ncia acentuada tem sido frequentemente apontada como poss?vel fator de risco para ocorr?ncia de traumatismo dent?rio. No entanto, a mordida aberta anterior, as mordidas cruzadas anterior e posterior e o apinhamento dental t?m sido pouco investigados e apresentam resultados n?o conclusivos na denti??o dec?dua. Assim, o presente estudo buscou investigar a influ?ncia das caracter?sticas oclusais na ocorr?ncia de traumatismo dent?rio em pr?-escolares. Trata-se de um estudo caso-controle de base populacional (1:1), realizado na cidade de Diamantina - Brasil. Ap?s a realiza??o de um estudo transversal as crian?as de 3 a 5 anos de idade com traumatismo dent?rio foram sorteadas para compor o grupo caso (n=200). O grupo controle foi composto por crian?as sem hist?ria de traumatismo dent?rio e pareadas com as crian?as do grupo caso empregando os seguintes crit?rios (1.escola, 2.sexo, 3.idade). As vari?veis independentes foram coletadas por serem de interesse para o estudo (caracter?sticas oclusais) ou por atuarem como potenciais confundidoras (vari?veis sociodemogr?ficas, h?bitos de suc??o e cobertura labial). Os valores de kappa intraexaminador e inter-examinador foram superiores a 0,80 para todas as condi??es bucais avaliadas. Para a an?lise dos dados utilizou-se o programa SPSS 22.0. Foram realizadas as an?lises descritiva, univariada e de regress?o log?stica simples e m?ltipla. Para cada vari?vel de interesse (caracter?stica oclusal), foram criados 5 modelos de ajuste para as vari?veis confundidoras. Na an?lise univariada, observou-se associa??o estatisticamente significativa para as vari?veis, apinhamento anterior superior (p=0,024), mordida aberta (p=<0,001), sobressali?ncia (p=<0,001) e cobertura labial (p=<0,001). Ap?s a regress?o log?stica, a mordida aberta anterior manteve a signific?ncia estat?stica nos cinco modelos de ajuste (OR= 3,80; IC 95%=1,42 ? 10,16). As vari?veis apinhamento anterior superior (OR=2,14; IC 95%=1,00 ? 4,63) e sobressali?ncia (OR= 1,12; IC 95%=0,58 ? 2,17) permaneceram associadas ao grupo caso, independentemente das vari?veis de confundimento (vari?veis sociodemogr?ficas, h?bitos de suc??o e cobertura labial), mas perderam a signific?ncia no modelo 5, quando foram ajustadas por outros tipos de m? oclus?o. Conclui-se que a mordida aberta anterior permaneceu fortemente associada ao traumatismo dent?rio, independentemente das vari?veis de confus?o e de outros tipos de m? oclus?o. / Disserta??o (Mestrado) ?

Accentuated overjet has been frequently pointed as a possible risk factor for dental trauma. However, anterior open bite, anterior and posterior crossbite and dental crowding have been little investigated and show non-conclusive results in the deciduous teeth. Therefore, the present study sought to investigate the influence of occlusal characteristics in the occurrence of dental trauma in preschool children. This is a population based case-control study (1:1), held in the city of Diamantina-Brazil. After conducting a cross-sectional study, children between the ages of 3 to 5 years old with dental trauma were randomly chosen to the case group (n=200). The control group was made of children without dental trauma history and paired with the case group children using the following criteria (1. school, 2. gender, 3. age). The independent variables were collected because of the studies? interest (occlusal characteristics) or because of its potential as a confounding factor (sociodemographic variables, suction habits and lip coverage). The intra and inter-examiner kappa values were greater than 0,80 for all of the oral conditions assessed. The SPSS 22.0 program was used for data analysis. The descriptive, univariate, simple and multiple logistics regression analysis were performed. For each variable of interest (occlusal characteristic), five adjustment models for the confounding variables were created. In the univariate analysis, statistically significant association was observed for the variables: superior anterior crowding (p=0,024), open bite (p=<0,001), overjet (p=<0,001) and lip coverage (p=<0,001). After logistic regression, anterior open bite kept the statistic significance in all five adjustment models (OR= 3,80; IC 95%=1,42 ? 10,16). The anterior superior crowding variable (OR=2,14; IC 95%=1,00 ? 4,63) and the overjet variable (OR= 1,12; IC 95%=0,58 ? 2,17) remained associated with the case group, regardless of the confounding variables (sociodemographic variables, suction habits and lip coverage), but lost significance in model 5, when adjusted for other types of malocclusion. In conclusion, anterior open bite remained strongly associated with dental trauma, regardless of the confounding variables and of other types of malocclusion.
