Root Resorption Associated with a Subepithelial Connective Tissue Graft for Root Coverage: Clinical and Histologic Report of a Case

This article reports on a case of root resorption following a clinically successful root coverage procedure with a subepithelial connective tissue graft on a maxillary lateral incisor. Two years after the graft procedure was performed, the tooth was extracted in conjunction with the buccal attachment apparatus. Histologic examination of the specimen revealed signs of active resorption of the dentinal surface and bone formation in the deepest portion of the resorption cavity. Possible causative factors of the root resorption process are discussed.
