摘　　要：目的:探讨3~6岁儿童乳前牙发育正常继承恒牙发育异常的发生情况。方法:选择2022年01月至2023年12月来我院就诊的3~6岁儿童,最终纳入17 656张曲面断层片,记录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:乳前牙发育正常继承恒牙发育异常总发生率为5.75%,男性多于女性(P=0.000<0.01)。继承恒牙异常类型有:多生牙、恒牙先天缺失和牙瘤,其中继承恒牙多生牙最常见,发生率为4.89%,男性多于女性(P=0.000<0.01)。多生牙1个者占76.13%,2个者占23.52%,发生于上颌中线区最多,占98.73%。继承恒前牙先天缺失157例,发生率为0.89%,先天缺失1个者占63.69%,先天缺失2个者占34.39%,性别间差异无统计学意义(P=0.552﹥0.05),左右侧之间无差异(P=0.175﹥0.05),上颌缺失多于下颌(P=0.001<0.05),单侧缺失多于双侧(P=0.000<0.01),先天缺失最常发生于上颌尖牙占41.70%、下颌侧切牙占18.83%、上颌侧切牙和下颌中切牙各占18.39%。继承恒牙并发牙瘤6例,发生率为0.03%。结论:乳前牙发育正常继承恒牙发育异常发生率为5.75%,继承恒牙有3种发育异常,可以导致未来恒牙列的异常,曲面断层片技术筛查继承恒牙和牙列的异常,早期发现和诊断,以便采取积极的治疗方案。AIM:To investigate the occurrence of dental development anomalies of inherited permanent teeth with normal development of anterior deciduous teeth in 3-6-year-old children.METHODS:A total of 17656 panoramic radiographs of 3-6-year-old children with deciduous dentition were collected from January 2022 to December 2023.The incidence of dental development anomalies of inherited permanent teeth was observed and analyzed.SPASS 24.0 software was used for statistical analysis.RESULTS:The total incidence of dental development anomalies of inherited permane nt teeth was 5.75%,which was higher in boys than in girls(P=0.000<0.01).The abnormal types of inherited permanent teeth include:supernumerary teeth,congenital permanent teeth absence and odontoma,among which supernumerary teeth is the most common,the incidence rate is 4.89%,and the male is more than the female(P=0.000<0.01).There were 76.13%of subjects had one supernum-erary tooth and 23.52%had two supernumerary teeth,and most of them occurred in maxillary midline region(98.73%).There were 157 subjects of congenital absence of inherited permanent anterior teeth(0.89%),63.69%of congenital absence of 1 tooth and 34.39%of congenital absence of 2 teeth.There were no significant differences between genders(P=0.552>0.05)and both sides(P=0.175>0.05).Maxillary absence was more than mandibular absence(P=0.001<0.05),and unilateral absence was more than bilateral absence(P=0.000<0.01).The most common subjects of congenital absence were maxillary cusp teeth(41.70%).Secondly,mandibular lateral incisor teeth was 18.83%.Third and fourth,maxillary lateral incisor teeth was18.39%and mandibular central incisor teeth was18.39%.There were 6 subjects with odontoma,the incidence was 0.03%.CONCLUSION:The incidence of dental development anomalies of inherited permanent teeth with normal development of anterior deciduous teeth is 5.75%,and there are three developmental abnormalities of inherited permanent teeth,which could lead to future abnormalities of permanent dentition.The application of
