Objectives: This study aimed to compare composite radiographic index (CRI-index) findings of medication-related osteonecrosis of jaws (MRONJs) and non-medication related osteonecrosis of jaws (n-MRONJs) and predict factors predictive of recurrence and healing delays. Materials and Methods: Patients referred to our clinic for stage 2 and 3 MRONJ and n-MRONJ between 2020 and 2023 were included in this study. Microorganisms were isolated in samples of excised bone obtained from the adjacent bone by surgery. CRI-index was evaluated using radiological data. Patient age, sex, causes and localization of osteomyelitis, as well as intraoperative and postoperative complications were recorded. Conclusion: presence was not a predictive factor for recurrence of any type of osteonecrosis. To predict recurrence and healing delays, more parameters need to be investigated.
