Abstract

Objective: The aim of this study was to evaluate the mandibular condyle and articular eminences of patients diagnosed with medication-related osteonecrosis of the jawbone (MRONJ) and those who use bisphosphonates (BP) but do not have MRONJ findings, by comparing them with a healthy control group.

Methods: The cone beam computed tomography (CBCT) images of 20 patients (15 male, 5 female) who were diagnosed with MRONJ and 20 patients (16 male and 4 female) who were using bisphosphonates but had no MRONJ were included in the study. A control group consisted of 20 age- and gender-matched patients (13 male, 7 female) who had no clinical complaints or signs and symptoms of TMD or rheumatic disease. The imaging characteristics relating to osseous changes of the condyles and in the articular fossa, such as flattening, erosion, osteophytes, subcortical sclerosis, subchondral cyst, loose joint bodies, joint space narrowing, flattening of the articular eminence, and resorption in the articular eminence, were evaluated. SPSS Statistics 20 software was used to statistically evaluate the data collected within the scope of the investigated variables. The results of the analyses were evaluated at 0.05.

Results: Analysis of temporomandibular joint osseous changes in the patient and control groups found statistically significantly higher subcortical sclerosis in both the patient group diagnosed with MRONJ and the patient group using BP, compared with the control group. In addition, a statistically significant difference was found between the patient groups and the control group in terms of condylar flattening, articular eminence flattening, and resorption.

Conclusion: Understanding the changes in physiological bone remodeling of the mandibular condyle after BP administration is crucial in the development of future treatment modalities for degenerative TMJ diseases that cause condylar bone resorption.

期刊介绍： As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
