Researchers have reported a high prevalence of TMDs among university students due to increased distress. The aims of this study were to determine the frequency of TMDs in Umm al-Qura University (UQU) dental students using the Diagnostic Criteria for Temporomandibular Disorders (DC\/TMD), and to examine the relationship between anxiety, bruxism, and TMDs among those students.\n                  <\/ns5:p>\n                  <ns5:p>\n                    <ns5:bold>Methods<\/ns5:bold>\n                    : The DC\/TMD pain screener questionnaire was completed by dental students. Students who reported TMD pain or had at least one positive TMD symptom were invited to the dental clinic for a full TMJ evaluation. History of bruxism was documented and an ultra-brief tool for detecting anxiety and depression (Patient Health Questionnaire-4 PHQ) was completed by all students.\n                  <\/ns5:p>\n                  <ns5:p>\n                    <ns5:bold>Results<\/ns5:bold>\n                    : A total of 240 students responded to the TMD pain screener in which 119 reported at least one TMJ symptom. Only 93 dental students presented to clinical examination in which 64.5% (n=60) of them had temporomandibular joint disorders. Disc displacement with reduction and local myalgia (38.7% &amp; 32.25%, respectively) were the most frequent diagnosis. A total of 29% (n=27) of students had more than one diagnosis. Overall, 41 participants (44.09%) reported a positive response to the anxiety scale and (n=38) 40% of participants reported parafunctional habits. Both the history of bruxism and anxiety were significantly related to TMDs (P=0.0002) and also significantly higher in women of higher academic years\n                    <ns5:bold\/>\n                    (P\u22640.01).\n                  <\/ns5:p>\n                  <ns5:p>\n                    <ns5:bold>Conclusions<\/ns5:bold>\n                    : This study found a high prevalence of TMDs among UQU dental students.
