摘要： 　　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畸形等，将乳牙融合牙对儿童口颌系统的危害降至最低。

Abstract: Objective To evaluate the prevalence and distribution of fused teeth in primary dentition of preschoolers in Kunming. Methods: 3116 children aged from 3 to 6 years old were randomly enrolled in a cross-sectional study. Fused teeth were assessed through visual examinations. Results Among the 3116 subjects, a total of 85 individuals (2.73%) presented with fusion of primary teeth without sex predilection. The fused teeth were typically located in the lower anterior region(89.41％),and mainly occurred unilaterally(83.53％). Of the 99 fused teeth, 7 (17.17)％was accompanied with caries, without predilection between left and right side. Conclusion A certain number of children suffer from fused teeth, which may cause series of complications, and pediatric dentists should pay more attention to fused teeth.
