Background and Aim: The objective of this study was to determine the prevalence of signsand symptoms of temporomandibular joint dysfunction (TMJD) in the Iran/Iraq war veteranssuffering from post-traumatic stress disorder. Materials and Methods: A total of 120 subjectsin the age range of 27 to 55 years were included; it included case group (30 war veteranswith PTSD) and three control groups (30 patients with PTSD who had not participated in theWar, 30 healthy war veterans, and 30 healthy subjects who had not participated in the War).All subjects underwent a clinical TMJ examination that involved the clinical assessment of theTMJ signs and symptoms. Results: The groups of veterans had high prevalence of TMJDsigns and symptoms vs. other groups; history of Trauma to joint was significantly higher insubjects who had participated in the war compare with subjects who had not participated inthe war (P = 0.0006). Furthermore, pain in palpation of masseter, temporal, pterygoideus,digastric, and sternocleidomastoid muscles in the groups of veterans was significantly greaterthan other groups (P < 0.0001). Clicking noise during mouth chewing was significantly differentbetween groups (P = 0.01). And, there was significant difference in the frequencies of maximumopening of the mouth between groups (P = 0.001). Conclusion: The results of this studyshowed that subjects’ war veterans with PTSD have significantly poorer TMJ functional statusthan the control subjects.
