摘　　要：目的基于口腔全景片和锥形束CT(CBCT)探讨多生牙患者发病状况及特点。方法横断面研究。2017年8月—2021年7月江南大学附属中心医院行口腔全景片检查的患者共35541例,其中男14460例、女21081例,年龄3~97(43.3±18.6)岁;纳入其中确诊为多生牙的患者1343例,其中男708例、女635例,年龄3~95(42.3±18.8)岁。1343例患者中,同时行CBCT检查者64例。观察项目:(1)根据年龄将患者分为<20岁、20~<40岁、40~<60岁、60~<80岁、≥80岁5个年龄段,统计多生牙的总体发生情况,比较不同性别间及不同年龄段多生牙的发生情况;(2)比较不同性别间多生牙的类型、位置、生长方向的差异;(3)在CBCT上观察不同类型多生牙及邻牙萌出受阻、邻牙牙根吸收、含牙囊肿等并发症的影像学特点,并比较不同性别间并发症发生情况的差异。结果(1)35541例患者中,发现多生牙1343例(1667颗),发生率3.8%;其中男性发生率为4.9%(708/14460),女性发生率为3.0%(635/21081);男女患病比例为1.1∶1(708∶635)。1343例1667颗多生牙,存在1颗多生牙的患者最多为1084例,4颗多生牙的患者最少为14例,不同性别间多生牙数的差异无统计学意义(χ^(2)=0.83,P=0.842)。不同年龄段组不同性别间多生牙占比比较,差异有统计学意义(χ^(2)=17.08,P=0.002)。(2)1667颗多生牙中,不同类型多生牙的占比由高到低男性依次为圆锥型38.0%(353/929)、磨牙型29.2%(271/929)、牙瘤样型19.5%(181/929)、切牙型13.3%(124/929),女性依次为圆锥型42.3%(312/738)、牙瘤样型27.5%(203/738)、磨牙型20.2%(149/738)、切牙型10.0%(74/738);多生牙的位置,男性、女性均最常发生于上颌,且均以上颌中切牙区占比最大[49.7%(462/929)、29.2%(216/738)];多生牙的生长方向,男性正常方向占比最大29.2%(271/929)、其次为倾斜方向24.5%(228/929),而女性以倾斜方向占比最大28.5%(210/738)、其次为正常方向26.8%(198/738)。不同性别间多生牙的类型、位�Objective This study aimed to investigate the incidence status and characteristics of patients with supernumerary teeth on the basis of oral panoramic radiographs and cone beam CT(CBCT).Method This study was a cross-sectional study.A total of 35541 patients,including 14460 males and 21081 females aged 3-97(43.3±18.6)years,who underwent oral panoramic radiographs at Jiangnan University Medical Center from August 2017 to July 2021,were included.Among them,1343 patients,including 708 males and 635 females aged 3-95(42.3±18.8)years,with a confirmed diagnosis of supernumerary teeth were included.Simultaneous CBCT was performed in 64 of the 1343 patients.Observational items:(1)Based on age,patients were divided into five age groups:<20 years,20-<40 years,40-<60 years,60-<80 years,and≥80 years.The overall occurrence of supernumerary teeth was statistically compared between different genders and the occurrence of supernumerary teeth among different age groups and between different genders.(2)Differences in the type,location,and growth direction of supernumerary teeth between different ages and senders were compared.(3)The radiographic characteristics of different types of supernumerary teeth and complications,such as disturbed eruption of the adjacent teeth,root resorption of the adjacent teeth,and dentigerous cysts,were observed on CBCT,and the differences in the occurrence of complications between different genders were compared.Results(1)Among the 35541 patients,1343(1667)were found to have supernumerary teeth,with an incidence of 3.8%.Among them,4.9%(708/14460)occurred in men and 3.0%(635/21081)occurred in women.The male-to-female ratio was 1.1∶1(708∶635).Of the 1343 patients with 1667 supernumerary teeth,those with one supernumerary tooth presented the most(1084 patients),whereas those with four supernumerary teeth presented the least(14 patients),and no significant difference was found in the number of supernumerary teeth between different genders(χ^(2)=0.83,P=0.842).Meanwhile,significant differences were
