A Cross Sectional Study of Prevalence of Temporomandibular Disorders in University Students

Aim – To investigate the prevalence of temporomandibular joint disorder (TMD) among university students. Material and methods – In this cross sectional prospective study, the sample consisted of 310 students (105 male and 205 female) with an age range from 18-25 years. The prevalence and severity of TMD was determined using a self reported anamnestic questionnaires. The symptoms were transposed into a severity classification according to the number and frequency of positive responses. Data was evaluated by the chi-square test between TMD severity and gender. Results – The result showed that 45.16% of students reported some level of TMD: 34.83% mild TMD; 8.38% moderate TMD; 1.96% severe TMD. No significant relationship was found between gender and TMD severity. Conclusion – A high prevalence of TMD was found in this student population, however most of cases were mild. The relationship between gender and TMD severity was not statistically significant. Despite suffering from TMD students were not aware of their disorders.
