This paper describes the incidence of complications following the surgical removal of impacted third molars in our department. Also dry soket, which had a highest incidence, were investigated for causal factors; skill of operator, age or sex of the patient. Results: 1. The complication was found in 8.89% of 574 surgical removals. The incidence of dry socket was 5.57%, delay in healing was 1. 57%, postoperative infection was 0.87%, postoperative nerve paralysis was 0.35%, postoperative bleeding was 0.17% and other complication was 0.35%. 2. The incidence of dry socket was 0.68% in the young patient group (under 20), 6.60% in the middle group (20-29) and 8.80% in the high age group (30-). The differences between in the young patient group and other patient groups were highly significant. These data suggested that age of the patient is one of the etiological factor of dry socket.
