287 - Odontoplasty of a Talon Cusp in a Maxillary Lateral Incisor

            A talon cusp is a form of dens evaginatus that occurs on the lingual surfaces of anterior teeth. It is an odontogenic developmental anomaly that consists of an outer layer of enamel, an inner core of dentin, and sometimes an extension of pulpal tissue. A talon cusp presents as a well-delineated additional cusp that extends to at least half the distance from the cementoenamel junction to the incisal edge, and some studies report it occurring in 1-6% of the population.

This case report details the treatment of a prominent talon cusp on a maxillary left lateral incisor in a healthy 9-year-old female patient. The interference in occlusion of the talon cusp on #10 resulted in its rotation as it erupted. After confirming there wasn’t a pulp chamber in the talon cusp via CBCT, sequential odontoplasty was completed over several visits to encourage de-rotation of #10 and to improve overall esthetics.
