Facial radicular groove in a maxillary central incisor. A case report

A facial radicular groove may occur in central maxillary incisors and act as a funnel for accumulating plaque and calculus. Since it is inaccessible to routine oral hygiene efforts of the patient and to treatment manipulations of the dentist, this anomaly predisposes the tooth to localized periodontal disease. Conservative or surgical treatment of such teeth should restore periodontal health by creating an environment more favorable for plaque control.
