摘　　要：目的:分析儿童非综合征型上颌前牙区多生牙(supernumerary teeth,ST)患病情况及X线片征象,为临床诊疗提供参考。方法:选取2016年9月1日~2021年8月31日于北京大学口腔医学院门诊部就诊的1~14岁上颌前牙区多生牙患者进行回顾性分析。对不同性别患者的多生牙数目、形态、方向等X线征象进行分类比较。应用SPSS 21.0统计软件进行统计分析。结果:(1)共收集无综合征病史及全身系统疾病上颌前牙区多生牙患者286例,男性219例,女性67例;(2)单个多生牙患者(203人)中,牙冠形态数量排序:锥型>补充型>结节型(分别为89.7%、9.9%、和0.5%),牙冠方向比例排序:正位>倒置>非垂直向(分别为63.4%、27.2%和9.4%);(3)同时有2颗多生牙患者82例,2颗多生牙外形分类不一致者21例,占比25.61%,一致者61例,其中锥型42例,补充型19例;2颗多生牙牙冠方向不一致者42例,多于方向一致者(40例)。结论:无综合征病史及全身系统疾病患儿上颌前牙区多生牙男性患者多于女性,以单个多生牙为主,锥型、正位居多,具有2颗多生牙的患者,牙冠外形及方向存在较大比例不一致的情况,不同性别间多生牙患者牙冠外形及方向构成比无统计学差异。Objective:To investigate the radiographic properties of supernumerary teeth(ST)in maxillary anterior region among children without syndrome.Methods:Pediatric patients(1-14 years old)with periapical or panoramic radiograph who visited our institution from 2016/9/1 to 2021/8/31 were included.The number,morphology,and orientation of ST were compared between different genders.Results:(1)286 subjects were included,among which 219 were male(76.6%)and 67 were female(23.4%).(2)Of 203 single ST cases,the most common shape was conical,followed by supplemental and tuberculate type(89.7%,9.9%,and 0.5%,respectively).Most of ST were in normal orientation,followed by inverted and horizontal orientation regarding the tooth axis(63.4%,27.2%,and 9.4%,respectively).(3)Of 82 patients with double ST,21 patients(25.61%)presented different morphology,61 patients presented the same morphology,among which 42 were conical-shaped ST and 19 were supplemental shape.Forty-two patients presented different orientation of ST and 40 patients presented the same orientation for the double ST patients.Conclusion:Males were more affected with ST than females.Most patients presented a single ST in maxillary anterior region.The most commonly shape was conical and the most commonly orientation was normal.For patients who have double ST,there were a significant proportion of inconsistent shapes and orientations.There were no significant differences in morphology and orientation between gender.
