ObjectiveThe current staging system of Medicine-Related Osteonecrosis of the Jaws (MRONJ) assigns patients to different stages based on clinical manifestations. The extent of bone disease could not be fully reflected without the radiologic evaluation. This missing information may lead to incorrect classification of MRONJ, and thus results in poor outcomes of treatment. The objective of this study was to compare CT and panoramic radiological features of MRONJ in different stages, in order to combine the clinical staging and imaging findings for accurate staging.Study DesignA retrospective study was carried out to analyze the differences in the radiographic feature of various clinical stages in MRONJ, as shown by panoramic radiography and Computed tomography.ResultsBoth panoramic radiograph (PR) and computed tomography (CT) could detect the typical syndrome of osseous sclerosis in Grade 0 and Grade 1. For the patients of Grade2, more features were observed on CT, such as periosteal reaction, cortical perforation and periosteal bone deposition. CT was also conducive to analyze the degree of the maxillary lesion and soft tissue involvement, as compared to PR.ConclusionThis study showed that CT detects more changes that may not be represented by plain radiography for patients with MRONJ.
