目的了解昆明地区乳牙融合牙的发生情况及分布特点。方法采用横断面研究方法,随机对3 116名3~6岁儿童进行口腔检查及记录。结果 3 116名儿童中乳牙融合牙发生率为2.73%,男女性别之间无统计学差异;在85例融合牙患儿中,76例（89.41%）发生于下颌,71例（83.53%）发生于单侧,14例（16.47%）两侧均有融合牙,且为对称性分布;在99颗融合牙中,16例（16.16%）发生龋坏,左右两侧发生率无统计学差异。结论乳牙融合牙有一定的发生率,好发于下颌前牙区,儿童口腔科医生应给予重视并密切观察,及时防治因乳牙融合继发的牙体牙髓、根尖周疾患,以及错牙合畸形等,将乳牙融合牙对儿童口颌系统的危害降至最低。
