摘要
目的:应用曲面断层技术研究牙齿发育迟缓的发生率和临床特点.方法:收集2022年01月至2023年06月就诊的5～14岁患者的曲面断层片,共纳入22338张,观察记录牙齿发育迟缓的发生情况,同时记录其他牙齿异常.应用SPSS 24.0统计软件分析所得的数据.结果:牙齿发育迟缓的发生率为1.37％(306/22338),牙齿发育迟缓在性别、左右侧和上下颌之间差异无统计学意义(P＞0.05);单侧发生多于双侧,先天缺牙组多于非缺牙组,两组间差异均有统计学意义(P=0.000).牙齿发育迟缓以1～2个为主,占96.41％(295/306),最常发生于下颌第二前磨牙,其次上颌侧切牙,再次上颌第二前磨牙.结论:牙齿发育迟缓在临床上常见,大多数为1～2个,多见于单侧,在先天缺牙人群中明显多于非缺牙人群,常见牙位为第二前磨牙和上颌侧切牙,对于牙齿发育迟缓的患儿,建议定期检查,密切关注牙胚发育情况.
Abstract
AIM:The incidence and clinical characteristics of delayed tooth development were investigated by performing panoramic radiographs.METHODS:A total of 22 338 panoramic radiograph of subjects aged 5 to 14 years were collected from January 2022 to June 2023,and the incidence of delayed tooth development was observed,and other dental abnormalities was recorded.SPSS 24.0 software was used for statistical analysis.RESULTS:The incidence of delayed tooth development was 1.37％(306/22 338).There was no significant difference between genders,left and right jaws,maxillary and mandibular(P＞0.05).There were more unilateral subjects than bilateral,and more subjects in congenital absence than no absence group,and the difference between the two groups was statistically significant(P=0.000).1 and 2 de-layed tooth development accounted for 96.41％(295/306)of our subjects.The mandibular second premolar was the fre-quently delayed tooth,followed by the maxillary lateral incisor and the maxillary second premolar.CONCLUSION:De-layed tooth development is common in clinic,most of which are 1～2,and unilateral.Delayed tooth development in congen-ital absence is significantly more than normal group.Most delayed teeth are the second premolar and maxillary lateral inci-sor.It is recommended to check regularly and pay close attention to tooth embryo development for children with delayed tooth.
