摘　　要：目的探讨我国江苏地区正畸患者中导致Bolton指数不调的几种常见原因。方法收集江苏省三个地区的正畸患者共1672人,分析其中先天缺牙、多生牙、过大牙、过小牙、融合牙、双生牙、釉质发育不良以及单纯Bolton指数不调等因素的比重。结果全牙Bolton指数不调者占总数的22.61%;单纯Bolton指数不调所占比例最多,先天缺牙者其次,过大牙、双生牙、釉质发育不良等较少。结论Bolton指数不调在正畸患者中有相当的比例,对于不同原因所致不调应对症治疗。Objective To investigate Bohon index discrepancy caused by different etiological factors. Methods 1672 orthodontic patients＇ data were collected. Proportions of agenesis, hyperdontia, macrodontia, microdontia, fused tooth, geminated tooth, amelogenesis imperfecta, and simple Bohon index discrepancy were calculated. Results The proportion of patients with whole Bolton index discrepancy was 22.61%, in which simple Bohon index discrepancy was the most common etiological factor, followed by agenesis. Macrodontia, fused tooth and amelogenesis imperfecta were relatively less. Conclusion Bolton index discrepancy is a frequently encountered disease, and symptomatic treatment should be adopted.
