Management of supernumerary tooth in association with talon cusp on the primary incisor

A talon cusp is an uncommon anomaly in the primary dentition. Since it was first reported in 1977, there have been only 37 documented cases in normal children. Most involved the primary maxillary central incisors, with five cases where the primary maxillary lateral incisors were affected. All the cases with talon cusps on the primary maxillary central incisors were not associated with any odontogenic abnormality of the corresponding permanent successor. However, in the five cases with talon cusps on the primary maxillary lateral incisors, three cases were associated with supplemental lateral incisors; one case had a supernumerary tooth while the condition of the permanent successor was not mentioned in the other case. In the present study, the primary maxillary lateral incisors in all three of the children with talon cusps were associated with supernumerary teeth which were all conical-shaped. A conservative approach was used to manage these non-inverted conical supernumerary teeth
