摘　　要：融合牙容易发生在下颌乳前牙,而畸形舌侧尖好发在上颌恒前牙。本文报道的是临床上较少见的单侧下颌中切牙和侧切牙发生融合且融合牙伴畸形舌侧尖1例,同时对本病例这两种发育异常的发生原因进行分析,提出相应的防治措施以应对其并发症的发生。Fused teeth and talon cusp, usually are two separate dental anormalies affecting both primary and permanent dentitions. Fused teeth are more commonly in deciduous maxillary anterior teeth, while the talon cusp is more common in permanent maxillary incisors. Here is a rare case of talon cusp in fused teeth affecting permanent mandibular incisors. We discussed the etiopathogenesis and a possible hypothesis of these two anomalies in order to improve the awareness on the lesion and find out preventive measure to reduce the complications.
