摘　　要：目的:探讨3~6岁儿童乳前牙发育异常的发生情况。方法:选择2023年1~12月来我院就诊的3~6岁儿童,最终纳入9432张曲面断层片,记录乳前牙和继承恒牙发育异常的情况,应用SPSS 24.0统计软件分析所得的数据。结果:乳前牙发育异常的总发生率为3.90%,性别间差异无统计学意义(P=0.483)。乳前牙先天缺失最常见,发生率为2.15%,性别间差异无统计学意义(P=0.887),单侧缺失多于双侧(P=0.000),下颌缺失多于上颌(P=0.000),右侧缺失多于左侧(P=0.000),乳前牙先天缺失其继承恒牙有4种情况(缺失70.85%,正常25.83%,融合牙1.85%和额外牙1.48%)。乳前牙融合牙的发生率为1.84%,性别间差异无统计学意义(P=0.110),单侧融合多于双侧(P=0.000),下颌融合多于上颌(P=0.000),右侧融合多于左侧(P=0.012),乳前牙融合牙其继承恒牙有3种情况(缺失52.33%,正常43.52%和融合牙4.15%)。乳前牙额外牙的发生率为0.13%,其继承恒牙有2种情况(额外牙33.33%,无额外牙66.67%)。乳前牙畸形舌尖的发生率为0.42‰,乳前牙双根的发生率为0.21‰,乳前牙阻生牙的发生率为0.11‰。结论:乳前牙发育异常发生率3.90%,乳前牙发育异常在一定程度上影响乳牙和乳牙列,甚至可能并发恒牙和恒牙列异常。对乳前牙发育异常的患儿,可通过影像学检查了解继承恒牙的情况,早期发现和诊断恒牙异常,以便采取合理的治疗方案。Objective:To investigate the occurrence of developmental anomalies of anterior deciduous teeth in 3-6-year-old children.Methods:A total of 9432 panoramic radiographs of 3-6-year-old children with deciduous dentition were collected from January 2023 to December 2023.The incidence of anterior deciduous and inherited dental developmental anomalies was observed and analyzed.Results:The incidence of anterior deciduous developmental anomalies was 3.9%,and the difference between the genders was not statistically significant(P=0.483).Congenital anterior deciduous teeth absence was the most common,with an incidence of 2.15%.There was no statistical difference between genders(P=0.887).The differences between unilateral and bilateral,maxillary and mandibular,right and left were statistically significant(P=0.000).Four types of congenital deciduous anterior teeth absence with inherited permanent teeth were observed(absent teeth 70.85%,visible teeth 25.83%,fused teeth 1.85%,and supernumerary teeth 1.48%).The incidence of anterior deciduous tooth fusion was 1.84%,and there was no statistical difference between genders(P=0.110).The differences between unilateral and bilateral,maxillary and mandibular were statistically significant(P=0.000).Tooth fusion in right was more than left(P=0.012).Three types of deciduous anterior fused teeth with inherited permanent teeth were observed(absent teeth 52.33%,visible teeth 43.52%,and fused teeth 4.15%).The incidence of supernumerary teeth in deciduous anterior teeth was 0.13%,and two types of inherited permanent teeth were observed(33.33%with supernumerary teeth and 66.67%without supernumerary teeth).The incidence of freakish lingual cusp in deciduous anterior teeth was 0.42‰,bi-rooted in deciduous anterior teeth was 0.21‰,and impacted in deciduous anterior teeth was 0.11‰.Conclusion:The anterior deciduous developmental anomalies partly affects deciduous teeth and deciduous dentition,and even complicates with permanent teeth and permanent dentition abnormalities.The application of ima
