The following results were obtained. 1.12.2% and 53.2% of the children reported subjective symptom and objective symptom and there was no signigicnat differences between the sexes and ages regarding the prevalence of signs and symptoms of temporomandibular disorder. 2.Clicking and crepitus were found in 9.0% and 2.2% of children and 40.4% and 28.7% of children reported muscle tenderness and joint tenderness no palpation, and there was no dignificant differences between the sexes regarding the prevalence of signs and symptoms of temporomandibylar disorder. 3.The distribution of Angle's classification was found 56.9% in ClassⅠ, 19.7% in ClassⅡ, 23.4% in Class Ⅲ, and correlations were found between malocclusion and subjective symptom(P<0.05). 4.The prevalence figures of posterior cross bite, andterior cross bite, openbite, deep and occlusal interference at the terminal hinge movement were 3.2%, 19.1%, 5.3%, 10.1%, and 9.0% respectively, and there was no significant difference between these factors regarding the prevalence of signs and symptoms of temporomandibular disorder. 5.Multiple loss of teeth, oral parafunction, trauma to the face were reported in 9.0%, 27.7%, and 19.1% of children respectively, and there was no signficant difference between these factors regarding the prevalence of signs and symptoms of thmporomandibular disorder. 6.Strong correlations were found between subjective symptom, joint tenderness and recurrent headache(P<0.01), and lateral joint tenderness was correlated to muscle tenderness especially masseter muscle (P<0.01).
