Abstract
The incidence of TMJ dysfunction symptoms in patients with malocclusion was evaluated by questionnaires and dental casts. Data was obtained from 281 orthodontic patients (84 males and 197 females) aged 4-51 years with a mean of 15.2 years.
The results show that 33 patients (11.7%) havea primary complaint of TMJ dysfunction. 66 patients (23.5%) have no complaint but they hada history of at least one symptom of TMJ dysfunction. 181patients (64.8%) were assessed to be normal and to be free of clinical symptoms of TMJ dysfunction. No significant sex differences were found in the incidence of TMJ dysfunction. The incidence of TMJ dysfunction increased with age. There was no substantial differences in the incidence of TMJ dysfunction between orthodontically treated patients and untreated ones. A significantly high incidence of TMJ dysfunction was found in patients with anterior open bite.
