Background: Temporomandibular dysfunction (TMD) represents the clinical conditions of the temporomandibular joint, the masticatory muscles, and the structures close to the joint with chronic pain, malfunction of the jaw and joint sounds. Individuals with TMD mainly complain of pain as well as fatigue, headache and restricted mandibular opening. The psychological factors were dispensable and explainable causes of TMD. Methodology: This is a cross-sectional study that assessed the prevalence of TMD by a pre-designed self-administrated questionnaire composed of 10 questions. This study aims to determine the psychological causes associated with TMD. The objectives also include identifying the most affected age group by the TMD, the most affected sexes and the most common symptoms, the duration or/and presence of TMD-related pain, suffering from bruxism, developing abnormalities of occlusion and the management strategies. Results: The study includes 166 patients, 75.3% of them are females. The prevalence of TMD is (44%), and the females were (60.3%). Most of TMD patients had stress, anxiety and depression (68.5%), and it has a significant association with TMD (P=0.039). Bruxism was present in 37% of the patients. Conclusion: TMD represents a critical health problem with negative effects on the patients as it affects their quality of life. This made the psychological factors of TMD a major concern. This study concluded a relatively high prevalence of TMD among our population. It also reported a ranking prevalence among females. It is worth mentioning that most of the patients suffered from stress anxiety and depression. Even though, the obvious comprehensive causes of TMD are not clear and not discussed well in most of the literature which implies defects in the management strategies as a consequence.
