Management of Supplemental Permanent Maxillary Lateral Incisors in Association With Talon Cusp on the Primary Predecessors: A Report of 3 Cases

Most of the cases of talon cusp in the primary dentition affected the maxillary central incisors, but have no effect on the permanent successors. Among the 5 cases of a talon cusp in primary maxillary lateral incisors reported in the dental literature, however, one was associated with a supernumerary tooth and 3 with supplemental permanent successors. The purpose of this report was to describe 3 cases of a talon cusp on the primary maxillary lateral incisors of Chinese children, all of which were associated with talon teeth or the permanent successors. A conservative approach was used to manage these supplemental permanent lateral incisors, and the advantages of such an approach are discussed.
