Background: It has been reported that Tempro-Mandibular-disorders (TMD) is the most common orofacial pain source of non-dental origin. The aim of this cross-sectional observational study is to explore the prevalence of signs and symptoms of TMD among a group of dental students in Benghazi-Libya. Methods: The examined group comprised 100 students [17 males and 83 females; mean age: 24.8±2.23 years. The assessment was undertaken following Helkimo's measures. The prevalence and severity of TMD was determined using a self-reported anamnestic questionnaire and clinical examination. Descriptive statistics was employed to explore the frequencies of the examined variables. Linear correlation coefficient was conducted between the reported symptoms and recorded signs and between the reported symptoms and the clinical dysfunction scores (CDS). The level of significance was set at P<0.05. Results: A total of 37% of the students reported some level of TMD symptoms [32% mild (Ai1); 5% severe (AiII)]. On the other hand, majority of the students (93%) demonstrated a range of TMD signs [76% mild (DiI); 17% moderate (DiII)]. Although linear correlation coefficient between the reported symptoms (Ai) and the recorded signs (Di) (r=0.32) and between the reported symptoms (Ai) and the CDS (r=0.37) were low, they were statistically significant (P<0.05). Conclusion: Mild to moderate prevalence of TMD appears to exist among Libyan dental students.
