摘　　要：目的对上颌前牙区多生牙的锥形束CT(CBCT)进行研究。方法回顾性分析南京医科大学附属苏州医院口腔科2022年1月至2023年12月期间诊治的80例患者的基本资料,对患者性别、年龄、多生牙萌出状态、多生牙形状进行统计与分析。结果80例患者共有110颗多生牙,均为儿童及青少年,患者平均年龄为(8.22±1.27)岁,男女比例11:5;80例多生牙患者中,包括乳牙列期4~6岁15例(18.75%),替牙列期7~12岁49例(61.25%),恒牙列期12~16岁16例(20.00%);多生牙形状中,包括发育完整型(与正常的前牙形态相似)2颗(1.82%),结节状6颗(5.45%),锥形97颗(88.18%),蕾状5颗(4.55%);多生牙萌出状态中,包括已经萌出14颗(12.73%),软组织阻生6颗(5.45%),骨组织阻生90颗(81.82%);不同性别患者的多生牙形状、萌出状态对比,差异显著(P<0.05)。结论上颌前牙区多生牙主要发生于儿童及青少年期,且女性发病率低于男性。多生牙形状中以锥形较多,多生牙萌出状态中以骨组织阻生患者较多。Objective:To study cone-beam CT(CBCT)of supernumerary teeth in maxillary anterior teeth.Methods:The basic data of 80 patients diagnosed and treated in the Department of Stomatology of Suzhou Hospital affiliated to Nanjing Medical University from January 2022 to December 2023 were retrospectively analyzed,and the sex、age、eruption state and shape of supernumerary teeth were statistically analyzed.Results:There were 110 supernumerary teeth in 80 patients,all of whom were children and adolescents.The average age of the patients was(8.22±1.27)years,and the ratio of male to female was 11:5.Among the 80 patients with supernumerary teeth,there were 15 cases(18.75%)in deciduous dentition,49 cases(61.25%)in mixed dentition and 16 cases(20.00%)in permanent dentition.The shapes of supernumerary teeth include 2(1.82%)fully developed(similar to normal anterior teeth),6(5.45%)nodular teeth,97(88.18%)conical teeth and 5(4.55%)bud teeth.The eruption of supernumerary teeth included 14 teeth(12.73%),6 soft tissue impacted(5.45%)and 90 bone impacted(81.82%).The shape and eruption state of supernumerary teeth in patients of different sexes were significantly different(P<0.05).Conclusion:supernumerary teeth in maxillary anterior teeth mainly occur in children and adolescents,and the incidence rate of women is lower than that of men.The shape of supernumerary teeth is more conical,and the patients with supernumerary teeth eruption are more impacted by bone tissue.
