This study was planned to evaluate the efficacy of surgical treatment in stage 2 medication related osteonecrosis of jaw(MRONJ) patients. Retrospective analysis was performed about patients who were treated with medication related osteonecrosis of jaw from 2015 to 2017. 25 Patients were treated by a single surgeon at the Department of Oral Surgery, Dental Hospital, Pusan National University. The treatment methods they received were conservative or surgical. The results of treatment were classified as "fail" and "success" and the prognosis according to the treatment method was compared. Conservative treatment 14.29% (2 cases), sequestrectomy 64.29% (9 cases) and saucerization 21.43% (3 cases) were performed in the MRONJ group, and 2 treatment failures were encountered after conservative treatment and 1 after saucerization. Surgical treatment resulted in better outcomes in stage 2 MRONJ patients. Furthermore, treatments were deemed successful when surrounding necrotic bone containing sequestrum was reliably removed. Therefore, this study suggests that the treatment of "stage 2" MRONJ should actively consider surgical treatment.
