Hypercementosis Progression With Evidence of Acquired Concrescence: A Case Report

This case report highlights the importance of periodic dental examinations in identifying progressive hypercementosis and its rare complication, root concrescence, which can complicate future dental extractions. Hypercementosis may be idiopathic or secondary to either local factors or systemic disorders. However, evolution to concrescence raises questions about future treatment approaches should the involved teeth become nonrestorable and require extraction. This article presents a case of generalized hypercementosis affecting multiple quadrants with progression. The severe hypercementosis led to concrescence of Nos. 25/26 and 29/30 surrounded by one joint lamina dura. Generalized wear was noted on all occlusal and incisal surfaces of dentition with periodontal pocket depths of teeth Nos. 29 and 30 buccally of 3 mm and 2 mm and distally of 3 mm and 4 mm, respectively. Periapical radiographs from full-mouth series x-rays revealed that the roots of both teeth were grossly thickened, bulbous, and blunted. Because of a lack of contributory medical history, the presumptive diagnosis was hypercementosis sequela to occlusal trauma.
