A study of the gingival injury associated with hand scaling has been reported. Following the former study, we would like to report a histopathological study of gingival injuries caused by ultrasonic scaling. Gingival biopsies were obtained 24 hours after hand or ultrasonic scaling, and they were compared each other histopathologically. The results are as follows; 1) Injury and tear of pocket epithelium were relatively slighter in ultrasonic scaling than those of hand scaling. 2) In the group of ultrasonic scaling, hemorrhagic changes has never been observed in the gingival tissue. Contraversely to hand scaling specimens, no hemorrhagic change around the base of pocket was found in ultrasonic specimens. 3) Comparative study of healing proscess of the gingival tissue following hand or ultrasonic scaling is on progress.
