摘要
目的探讨锥形束CT在儿童上颌前牙区多生牙定位中的应用价值。方法回顾性分析2019年5月至2020年5月医院收治的60例上颌前牙区多生牙患儿的临床资料,所有患儿均接受锥形束CT检查,分析多生牙数目、形态、埋伏位置、临床分型、弯曲情况及生长方向。结果60例患儿,经锥形束CT检查发现,单个多生牙54例,2个多生牙6例,合计66颗多生牙。66颗多生牙的形态以类切牙形为主,占比60.61%;埋伏位置多见腭侧埋伏,占比78.79%;临床分型多见全部骨埋伏型(Ⅱ型)、部分骨埋伏型(Ⅰ型),分别占比50.00%、36.36%;弯曲情况多见无牙根弯曲,占比74.24%;生长方向以倒置阻生最为常见,占比45.45%。结论锥形束CT可精准显示上颌前牙区多生牙的数目及其与周围组织的关系,从而确保上颌前牙区多生牙诊断、定位的准确性,为后续临床治疗奠定基础。
Objective The application value of cone beam CT in the positioning of supernumerary teeth in children's maxillary anterior area was explored.Methods The clinical data of 60 children with supernumerary teeth in maxillary anterior area treated in the hospital from May 2019 to May 2020 were analyzed retrospectively.All children underwent cone beam CT.The number,shape,ambush position,clinical classification,bending and growth direction of supernumerary teeth were analyzed.Results The cone beam CT examination results of 60 children showed that there were 54 cases of single supernumerary tooth and 6 cases of two supernumerary teeth,and the total number of supernumerary teeth were 66.The shape of 66 supernumerary teeth was mainly incisor like,accounting for 60.61%;Palatal ambush was common in the ambush position,accounting for 78.79%;The clinical classifications were all bone ambush(type Ⅱ)and partial bone ambush(type Ⅰ),accounting for 50.00% and 36.36% respectively;No root bending was common in bending,accounting for 74.24%;The most common growth direction was inverted impaction,accounting for 45.45%.Conclusion Cone beam CT can accurately display the number of supernumerary teeth in maxillary anterior area and its relationship with surrounding tissues,so as to ensure the accuracy of diagnosis and positioning of supernumerary teeth in maxillary anterior area and lay a foundation for subsequent clinical treatment.
