A rare presentation of multiple talon cusps

Abstract

A talon cusp is a relatively rare dental developmental anomaly characterized by the presence of accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. It is frequently found on the palatal surface of the maxillary anterior teeth in the permanent dentition. The etiology is controversial, but it is suggested that this condition has a multifactorial cause, including both genetic and environmental factors. Radiographically talon cusps are radiopaque structures, in which the enamel, dentin and occasionally the pulp can be seen. The alteration is generally asymptomatic, but it may cause clinical problems eventually. Early diagnosis is important to prevent occlusal interference, irritation of the tongue, pulpal necrosis, caries and periodontal alterations. Clinical management of talon cusps may be either conservative or radical, depending on the size and shape of the affected tooth. We report a rare case of talon cusps involving all six maxillary anterior teeth in a 20-year-old patient.
