Evaluation of signs and symptoms of temporomandibular disorders and incisal relationships among 7-10-year-old Turkish children with sleep bruxism: A cross-sectional study

Abstract

Objective: To study the signs and symptoms of temporomandibular disorders (TMDs) and incisal relationships related to sleep bruxism and parafunctional habits among children.

Methods: The study consisted of 106 children (53 with and 53 without bruxism) between the ages of 7 and 10. A general questionnaire and Diagnostic Criteria for Temporomandibular Disorders Axis I examination form were used for each child.

Results: There were significant differences between children according to pain, headache, midline deviation, opening pattern, temporomandibular joint noise, overjet, overbite, corrected deviation, and pain disorders (p < 0.05). According to the logistic regression, the higher scores of "mouth breathing" and "horizontal incisal overjet" were independent risk factors for TMDs. The lack of "bruxism" and "sleeping with open mouth" were protective factors for TMDs.

Conclusion: Children with bruxism showed signs and symptoms of TMDs and divergence in incisal relationships.
