Fibrous dysplasia-a 13-year retrospective radiographic analysis in a south Indian population

Objective: The aim of this study was to examine the clinical and radiographic presentation of fibrous dysplasia through a 13-year retrospective study in patients who reported to the outpatient unit of Government Dental College, Trivandrum. Methods: The clinical file records and radiographs of the patients who reported to the outpatient clinic in the Department of Oral Medicine and Radiology were retrospectively reviewed for histopathologically diagnosed fibrous dysplasia. A detailed analysis of the clinical and radiographic features of the 24 cases retrieved was carried out. Results: The male-to-female ratio of incidence was approximately 1:1. Most of the patients were in the second or third decade of life. Almost all the patients presented with a complaint of swelling on the side of the face. The mandible was more frequently involved than the maxilla. The most common radiographic pattern observed was the "ground-glass" appearance. Most of the patients exhibited expansion of the involved bone and loss of lamina dura of associated teeth. Conclusion: The awareness of protean features of fibrous dysplasia evident through this study is essential in the accurate diagnosis and proper treatment planning of such lesions.
