Total samples are390 persons (195 Buginese dan 195 Mandarnese). The condition of periodontal tissuewere checked using CPITN from WHO. Of 195 samples, 88 samples of Buginese and 55samples of Mandarnese were edentulous. The result showed periodontal disease ofBuginese were bleeding 2.8%, tartar 39.25%, pocket of 4-5 mm depth, 50.47%, andpocket of 6 mm depth, 7.48%. Periodontal disease of Mandarnese ethnic were bleeding2.14%, tartar 53.57%, pocket of 4-5 mm depth 21.43%, and pocket of 6 mm depth22.86%. Therefore, the need for periodontal treatment for aging Buginese were brushingteeth instruct 100%, prophylaxis 97.19%, and restorative 7.46%. Aging Mandarnese;were brushing teeth instruction 100%, prophylaxis 97.85%, and restorative 22.86%.
