Abstract
Introduction: The inclination of articular eminence (AE) varies across population. The AE dictates the path of condylar movement as well as the degree of rotation of the disc over the condyle. Mechanical conditions caused by aging and influenced by the loss of teeth might have some effect on remodulation and reshaping of the AE. Aim and Objective: The aim of the study was to compare the inclination of AE of temporomandibular joint (TMJ) in dentulous and edentulous elderly patients. Materials and Methods: Orthopantomogram scans fulfilling the inclusion criteria for dentulous and edentulous patients were included in the study. Patients with age range of 50–70 years were divided into two groups: Group A (dentulous) and Group B (edentulous). The inclination of AE was measured and compared. Results and Conclusion: Mean AE Inclination (AEI) value in dentulous and edentulous was 36.56 degrees and 30.16 degrees, respectively. The AEI was significantly increased in dentulous patients as compared to edentulous patients. The results of the current study are of great relevance as it suggests that maintenance of dentition is necessary to retain the proper physiologic function of TMJ.
