A morphological survey of proximal root concavities: a consideration in periodontal therapy.

Tooth morphological structure may often influence the success of periodontal therapy. The purpose of this study was to determine the existence, dimensions, and locations of proximal root concavities. The dentist's ability to perform satisfactory root surface preparation, the patient's ability to maintain effective plaque control, and the restorative implications of proximal root concavities are also discussed.
