The sample were oral benign lesions patients who had dredging treatment at Ibnu Sina Hospital, Makassar. Results: There were 20 cases that had dredging, 15 (75%) cases used obturator after dredging I, recurrence occurred in 2 (40%) of these cases, dredging II then was done and no recurrence occurred afterwards. There were 4 (15%) cases that did not use obturator after dredging I, recurrence occurred in 4 cases, 3 cases then had dredging II and use obturator, no recurrence afterward, while 1 case that did not use obturator after dredging II showed recurrence. Then dredging III and obturator insertion was done in this case, follow up showed no recurrence. Conclusion: dredging with obturator can reduce the recurrence rate of oral benign lesions.
