From October 2003 through December 2004, a sample of 10 cases (all female aged, 20-50 years old) clinically diagnosed of myofascial pain were followed up to identify changes in mandibular movements. The patients were interviewed, and anamnesis and a clinical examination were performed. Patients with a diagnosis of myofascial pain were recorded with an electronic axiograph (Kavo, model Arcus digmaâ?˘) and their bite force was measured (Kratosâ?˘ digital dynamometer). The patients were then instructed about treatment and follow-up was carried out. After the remission of symptoms, a new axiography and determination of bite force was performed. Axiograph analysis showed significant changes in the mandibular dynamic pattern between the symptomatic and asymptomatic phases and a statistically significant (p<0.001) increase in bite force in 100% of the patients after pain remission was verified. The changes in mandibular dynamics were: an increase in maximum jaw opening without pain in 100% of the sample and a decreased mandibular deviation in opening and closing jaw movements in 70% of the patients. The present study suggests that axiographic study of mandibular movements and the determination of bite force can contribute to a better understanding of temporomandibular disorders, and an improvement in diagnostic criteria and the follow-up of therapeutic procedures.
