The prevalence of temporomandibular disorders in war veterans with post-traumatic stress disorder.

The purposes of this study were to assess the prevalence of temporomandibular disorders in Croatian war veterans suffering from post-traumatic stress disorder (PTSD) and to analyze the impact of the disease on mandibular function. One hundred eighty-two male subjects participated in the study. The examined group consisted of 94 subjects who had taken part in the war in Croatia and for whom PTSD had previously been diagnosed. Patients were compared with an age- and gender-matched group of subjects who had not taken part in the war and for whom PTSD was excluded by means of a psychiatric examination. The study used a clinical examination and standard questionnaire. Statistically significant differences were found in almost all measured parameters. With regard to restricted movements, overbite, and overjet, the differences obtained did not have clinical significance. The most significant differences were found in the parameters of pain. Headache was experienced by 63.83% of the subjects with PTSD, facial pain by 12.77%, and pain in the region of the jaw by 10.64%. Headache was the most intense pain, with an average intensity of 4.92 on a scale of 0 to 10. Pain on loading, temporomandibular joint clicking, and intrameatal tenderness were more prevalent in the PTSD group than in the healthy control group. The study supports the concept that PTSD patients are at increased risk for the development of temporomandibular disorder symptoms.
