title: Atypical localized deep pocket due to a cemental tear: case report.
abstract: A 71-year old patient with a history of minimal periodontal attachment loss presented with an asymptomatic, non-bleeding, isolated deep pocket on the mesio-facial of a central incisor. Such localized, deep pockets are most frequently associated with a root fracture or an abscess, but in this case an atypical ledge-like projection determined to be a cemental tear was detected at the base of the 6 mm pocket. Periodontal flap surgery revealed a partial detachment of the cementum. Uneventful resolution of the pocket was achieved following root planing to remove the cemental fragment and placement of a bone graft and resorbable membrane. This article reviews the nature, predisposing factors, causes, clinical significance, and treatment of cemental tears.
