Abstract

Abstract: Introduction: Although many studies are being carried out with sleep bruxism, the literature points to a lack of studies with methodological quality in children.

Objective: To evaluate the behavioral and clinical aspects associated with probable sleep bruxism in early childhood.

Material and method: A cross-sectional observational study carried out with 371 children between 4 and 6 years of age. Parents answered a questionnaire with aspects related to their children's sleep behavior. Among the clinical characteristics, the presence of lip sealing, clicking, teeth marks on the jugal mucosa, and the side of the tongue was evaluated. Tooth wear was assessed using the BEWE index criteria. Simple logistic regression models were adjusted for each independent variable, estimating the gross odds ratios with the respective 95% confidence intervals. Variables with P <0.20 in the individual analyzes were adjusted in a multiple logistic regression model, with those with P ≤ 0.05 remaining in the model.

Result: 42.4% of parents reported that their children gritted their teeth while sleeping. Children who showed wear on their teeth were 1.53 times more likely to grind their teeth. There was no significant association with the other variables analyzed (P > 0.05).

Conclusion: Behavioral aspects were not associated with probable sleep bruxism. Among the clinical characteristics evaluated, tooth wear showed an association, which may indicate the probable bruxism of sleep in early childhood.

Resumo

Resumo: Introdução: Embora muitos estudos estejam sendo realizados com o bruxismo do sono, a literatura aponta uma carência de estudos com qualidade metodológica em crianças.

Objetivo: Avaliar os aspectos comportamentais e clínicos associados ao provável bruxismo do sono na primeira infância.

Material e método: Estudo observacional transversal realizado com 371 crianças entre 4 e 6 anos de idade. Os pais responderam a um questionário com aspectos relacionados ao comportamento do sono de seus filhos. Entre as características clínicas, foram avaliados a presença de selamento labial, estalidos, marcas dos dentes na mucosa julgal e na lateral da língua. O desgaste dentário foi avaliado por meio dos critérios do índice de BEWE. Foram ajustados modelos de regressão logística simples, para cada variável independente, estimando-se os odds ratios brutos com os respectivos intervalos de 95% de confiança. As variáveis com P< 0.20 nas análises individuais foram ajustadas em um modelo de regressão logística múltipla, permanecendo no modelo aquelas com P ≤ 0.05.

Resultado: 42.4% dos pais relataram que seus filhos rangiam os dentes enquanto dormiam. Crianças que apresentaram desgastes nos dentes, tinham 1.53 vezes mais chances de ranger os dentes. Não houve associação significativa com as demais variáveis ​​analisadas (P> 0.05).

Conclusão: Aspectos comportamentais não apresentaram associação com o provável bruxismo do sono. Entre as características clínicas avaliadas, o desgaste dentário apresentou associação, podendo ser um indicador para o provável bruxismo do sono na primeira infância.
