Evaluation of Association Between Dental Occlusion and Temporomandibular Joint Disorders

Temporomandibular disorders (TMD) are a class of degenerative muscular conditions associated with morphological and functional deformities. The aim of this study was to evaluate the association between dental occlusion and the occurrence of TMD among the patients visiting a private dental college. Among 86000 dental patients reported to our institution from June 2019 to March 2020, about 110 cases were included in the study by a simple random sampling method.These included 55 patients with temporomandibular disorder, and 55 patients without temporomandibular disorder. Any completely edentulous patients were excluded from the study. Each patient's dental records, treatment reports and photographs were reviewed thoroughly. Dental occlusion was evaluated and classified into class I malocclusion, class II div 1 malocclusion, class II div II malocclusion, and class III malocclusion. Demographic details like age, gender was also recorded.The collected data was validated, tabulated and analysed with Statistical Package for Social Sciences for Windows, version 23.0 (SPSS Inc., Chicago, IL, USA) and results were obtained. P value < 0.05 was considered statistically significant
