Prevalence of Temporomandibular Joint Disorders (TMD) Among Dental Students in Yemeni Universities: Multi Center Cross Sectional Study
##plugins.themes.bootstrap3.article.main##
Abstract
Background: Disorders of the temporomandibular joint (TMD) are common conditions that impact jaw function, frequently linked to stress, lifestyle elements, and genetic factors. Due to academic pressures and lifestyle practices, dental students may be at an increased risk of developing TMD.
Objective: This research intends to evaluate the prevalence of TMD among dental students at Yemeni universities and examine possible links with demographic factors, symptoms, and triggers.
Method: A cross-sectional survey was carried out with 482 dental students from several Yemeni universities. Data were gathered using an online questionnaire, which included demographic information, TMD symptoms, triggers, and lifestyle practices. The study assessed the occurrence of symptoms such as jaw pain, clicking noises, and headaches, alongside factors like stress, alcohol use, and smoking.
Results: Findings indicated that stress was a significant contributing factor to the notable prevalence of TMD symptoms among individuals. Symptoms of TMD, including headaches (18.9%) and jaw clicking (14.7%), were more frequently reported in female students. TMD symptoms were also associated with lifestyle habits such as alcohol consumption and smoking (6.4%). Despite experiencing symptoms, only 25.7% of students sought medical help.
Conclusion: The research concludes that stress plays a significant role in the heightened prevalence of TMD among dental students. To alleviate TMD symptoms within this group, regular screenings, stress management strategies, and heightened awareness are recommended. Longitudinal studies should be prioritized in future research to understand the progression and long-term impacts of TMD.
