Prevalência das maloclusões e dos índices anamnésicos e clínicos, em pacientes com disfunção da articulação temporomandibular

The authors analyzed the frequency of malocclusion, Helkimo (1974) anamnestic and clinical dysfunction indexes in patients with temporomandibular joint dysfunction and their possible correlation. One hundred and ten patients with these conditions were evaluated independent of age and gender. Signs and symptoms were evaluated, indicating levels of Helkimo indexes, Angle classification, over-jet, over-bite, cross-bite and missing teeth. The authors concluded that there was a high incidence of Angle class II and overjet larger than two milimeters. Among the Helkimo indexes there was a slight predominance of Anamnesthic Index AiII (symptoms of severe dysfunction) and Clinical Index level DiI (mild dysfunction). A statistically significant relationship was found between the Clinical Index and the Angle classification as between Anamnestic Index and overbite.
