Abstract :

Background: Temporomandibular joint disorders (TMJD) can cause joint pain, trismus, and headaches, which negatively impact people's quality of life and may lead to a decrease in educational level among students. Thus, this study aimed to investigate the symptoms of TMJD among students at Isfahan Azad Dental Faculty. Materials and methods: This descriptive-analytic study involved 62 students from Isfahan Azad Faculty of Dentistry. Pain intensity (cephalic, joint, muscle) was evaluated using the VAS scale. After completing the evaluation of the students and registering the information in the relative checklist, data were analyzed using Exact Fisher and chi-square statistical tests(α=0.05). Results: The study found that students with headaches did not have a higher incidence of restriction in opening their mouth and joint pain. However, students with headache had lower rates of joint noise (p = 0.04). The age of students was not related to TMD (p>0.05), and gender was not related to joint noise (p= 1.00) and joint pain (p= 0.70). The malocclu-sion status of students was not related to TMD. Parafunctional habits were related to head-aches among students (p< 0.001). Conclusion: Severe headaches were common among studied students which could be related to temporo-mandibular joint disfunction as it was related to parafunctional habits. TMD symptoms were not related to age, gender (except for mouth opening restriction) and occlusion class type .
