Talon Cusp On Permanent Maxillary Canine: A Rare Case Report

teeth are varied. One such rare anomaly affecting the shape of anterior teeth is taloncusp. It is an accessory cusp-like projection found on lingual or labial surfaces of theupper or lower incisors, unilaterally or bilaterally in both dentitions. It is composed ofnormal enamel and dentine, with or without pulp. It is thought to develop as a result ofevagination on the surface of a tooth during morphodifferentiation stage. Reportedincidence is 0.04-10%, with higher prevalence in males. It is more common inpermanent dentition with a predilection for maxillary lateral incisors (55%), followed bycentral incisors (36%) and canines (9%). Talon cusp may cause problems like irritationof tongue during speech and mastication, occlusal interference, caries susceptibility anddisplacement of the affected tooth, and esthetics. Its treatment ranges from applicationof sealant to gradual reduction to root canal therapy. Early diagnosis of talon cusp andits treatment can avoid complications related to this anomaly.
