Association between possible sleep bruxism and sleep characteristics in children.

AIMS: To evaluate the relationship between possible sleep bruxism and sleep characteristics in children.

METHODOLOGY: A cross-sectional study was conducted through data collection of a pre-tested questionnaire answered by 111 parents on behalf of their children in the waiting room during their appointment at the Pediatric Dentistry Clinic of a public Brazilian university. The diagnosis of possible sleep bruxism was based on the international classification of sleep disorders (ICSD) criteria. The Chi-square test and logistic multinomial regression test were used in the statistical analysis.

RESULTS

The final model of logistic multinomial regression demonstrated that children with muscle pain in the mouth region (OR = 19.70 95% IC = 1.82-212.69), snoring (OR = 8.25 95% IC = 2, 56-26, 54), and those with parents with possible sleep bruxism have more of a probability of sleep bruxism.

CONCLUSION

Potential sleep bruxism tends to be hereditary. Muscle pain, snoring, and mouth breathing were important signals associated with possible sleep bruxism among children.
