The aim of this study was to determine the incidence of temporomandibular dysfunction (TMD) in veterans of the War for Independence, who suffer from posttraumatic stress disorder (PTSD. The examined group consisted of 100 male subjects with a diagnosis of PTSD, who had participated in the war, and a control group of 94 subjects of the same age and sex who had not participated in the war and in whom psychiatric diagnosis excluded PTSD. The study consisted of case history data and a medical examination. The examination included a questionnaire in which subjects answered questions with yes−no answers. During the medical examination the condition of the jaw joints (sounds, sensitivity and pain during palpation of the jaw joint) and mastication muscles (sensitivity and pain during palpation of the masticatory muscles) was assessed and the functional ability of the stomatognathic system determined (maximal opening, maximal laterotrusion movement left and right and maximal protrusion with registration of eventual occurrence of pain or sound). Statistically significant difference was determined in almost all measured parameters. The subjects with PTSD had subjective symptoms and clinical signs of temporomandibular disfunction (TMD) significantly more frequently. Eighty-two percent (82%) of those with PTSD had at least one symptom and 98% at least one sign of dysfunction, compared with 23.91% and 50% respectively of the subjects in the control group. The most frequent sign in both groups was sound in the temporomandibular joint (TMJ), which occurred in 64% of subjects with PTSD and 17.3% of subjects in the control group. Statistically significant difference was also found in the limitation of maximal possible movements, i.e. the subjects with PTSD had significantly more often restricted movements in opening, left and right laterality and protrusion. The greatest differences between the groups related to parameters of pain. Namely, 52% of subjects with PTSD had painful TMJ and 91% had at least one painful muscular location. It can be concluded that correlation exists between PTSD and TMJ.
