Examination-Related Stress Leads to Temporomandibular Joint Disorders in Medical and Dental Students - An Institutional-Based Study

Abstract

<p><strong>Background and Objective:</strong> Stress-related behaviors such as challenging academic atmosphere and rigorous examinations exert a negative impact on the normal function of temporomandibular joint. This study aimed to determine the prevalence and severity of temporomandibular joint disorders (TMDs) and their association with examination-related stress among medical (Bachelor of Medicine and Bachelor of Surgery) and dental (Bachelor of Dental Surgery) students.</p>
 <p><strong>Methods:</strong> This cross-sectional survey was conducted at Fatima Memorial Hospital, College of Medicine and Dentistry, Lahore, Pakistan, from June 2022 to November 2022 using the Fonseca’s Questionnaire. A total of 198 medical and dental students were included as study participants. They were required to select just 1 response for each of the 10 items mentioned in the adopted but customized and validated questionnaire. TMD was categorized as mild, moderate, severe, or no TMD based on the sum of these responses. The data were analysed using statistical software and a p-value less than or equal to 0.05 was set as significant.</p>
 <p><strong>Results:</strong> There were 52 (26.2%) males and 146 (73.7%) females with a mean age of 24.2 +1.22 years. Among 198 students, 104 were dental students while 94 were medical students. The prevalence of TMD was found to be 63.6% among all students. There was no TMD in 36.4% of students while 42.9% of students had mild TMD, and moderate and severe TMD was found in 14.1% and 6.6% of students, respectively. Mild (74%) and severe (6.7%) TMD were more prevalent in dental students than in medical students while moderate TMD was found more in medical students (16%). However, these differences were statistically not significant between dental and medical students (p > 0.005).</p>
 <p><strong>Conclusion:</strong> TMD was found in both medical and dental students with no significant difference in severity between them. The study indicates the need to take on certain preventive and therapeutic strategies to address this disorder among anxiety-prone medical and dental students.</p>
