Hubungan antara kebiasaan parafungsional dan gangguan temporomandibula pada anak usia remaja (Kajian terbatas di Jakarta)

Abstract

Background: Temporomandibular disorders (TMD) are musculoskeletal disorders involving the temporomandibular joints, masticatory muscles, and associated structures. The etiology of temporomandibular disorders is complex and multifactorial. Parafunctional activities are considered main factors that are associated with TMD. Objective: To examine the association between parafunctional habits and temporomandibular disorders in adolescence. Methods: An analytical observational study with a cross-sectional design was carried out on 443 children (236 men and 207 women) aged 12-13 years. The data obtained consisted of univariate and bivariate data on parafunctional habits and temporomandibular disorders based on the results of the adolescent’s questionnaire V.2. The data were analyzed by Chi-square test. Result: Bivariate analysis showed a significant association (p <0.05) between sleep clenching and awake clenching with temporomandibular pain (p = 0.047 and p = 0.001). A significant association was found between sleep grinding and biting the lips / cheeks habits with joint sounds (click / pop) (p = 0.045 and p = 0.020). Analysis of the association between sleep grinding and sleep clenching with limited jaw motion also showed a significant association (p = 0.014 and p = 0.004). Conclusion: There are associations between clenching and temporomandibular pain; sleep grinding and biting the lips / cheeks with joint sounds (click / pop); and between sleep bruxism and limited jaw motion.
