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.
乳牙列中多数融合尖病例累及上颌中切牙，但对恒牙列后继牙无影响。然而，在牙科文献报道的5例上颌乳侧切牙融合尖病例中，1例与多生牙相关，3例与额外的恒牙列后继牙相关。本报告的目的是描述3例中国儿童上颌乳侧切牙融合尖病例，所有病例均与融合牙或恒牙列后继牙相关。采用保守方法处理这些额外的恒牙列侧切牙，并讨论了这种方法的优点。
