In order to inrestigate the correlation between temporamandibular joint signs and symptoms and oral conditions, including occlusion, of the elderly 61 persons over 80 years old with more than 20 teeth were examined. The results were as follows: (1) Twenty-two persons (36.9%) had temporamandibular joint sounds. However, none had subjective symptoms of temporomandibular joint sound. (2) Fifteen persons (24.6%) showed morphological bone changes of the condyles. (3) One male had the subjective symptom of limitation of mouth opening and another male had the subjective symptom of pain of the masseter. (4) Temporamandibular joint sounds were dosely associated with female, loss of molar teeth, and loss of bilateral second molar tooth in that order by multivariate analysis. (5) The morphological bone changes of the condyles were closely associated with female by multivariate analysis.
