[Clinical studies on temporomandibular arthrosis in our dental clinic. 1. Subclinical female patients (20s-40s-year-old)].

Clinical study was done concerning to temporomandibular (TM) arthrosis for 168 female patients (mean age 35.5 ranged from 20 to 48 years) who visited our dental clinic. Among 168 patients, 16 cases (9.5%) had maxillofacial pain, 74 cases (44%) joint sounds and 49 cases (29.2%) alternations in the opening pathway. As a result, subclinical patients were 96 cases (57%). The mean value of maximum inter-incisal distance was 47.6mm +/- 5.3. The patients with subclinical TM arthrosis were mainly associated with stiffness of neck. They show in mothers with a number of infants. In female, it seems that delivery and nursing are associated with arising TM arthrosis.
