The maxillary incisors, both the central and lateral, are the most likely teeth to have a talon cusp, which is an extra cusp on the lingual surface. Talon cusps range from less than 1% to 6% of the population, and 33% of cases occur on the permanent maxillary central incisor.[24] Deciduous teeth are unlikely to have talon cusps. Also, the permanent maxillary incisors are the most likely teeth to have a dilaceration, which is a sharp curve on a tooth.[25]
