Abstract
600 randomly selected subjects from an urban community in Hungary were examined anamnestically and clinically concerning signs and symptoms of mandibular dysfunction. The anamnestic (Ai) and clinical dysfunction (Di) indices according to Helkimo were used. The percentage distribution of the sample was the following: AiO = 79.3%, AiI=15.3%, AiII = 5.3%; DiO = 20.1%, DiI = 72.3%, DiII = 7%, DiIII = 0.5%. Headache was reported in 23%, bruxism in 10%, joint sounds in 9%, pain in the face, neck, or around the ears in 6%. Clinical signs found at the examination were joint sounds in 46% (crepitation 29%, clicking 22%), muscle tenderness on palpation in 17%, joint tenderness in 3%, pain on movement in 2.5%, restricted mouth opening in 4%, deviation of the mandible in 20%.
