摘要:
目的 使用锥形线束CT(CBCT)影像技术分析福州地区儿童下颌第一乳磨牙牙体及髓腔形态,为乳牙临床诊疗及相关教学、科研工作提供参考依据。方法 共纳入福州地区119例患儿的CBCT影像,并使用Mimics、3-matic等软件分析牙体形态,对牙髓腔进行三维重建并进行数据分析,记录下颌第一乳磨牙根管数目及分布情况、根分叉处髓室高度、髓室顶及髓室底厚度,对比以上数据是否存在性别差异,统计牛牙样牙发生率。结果 下颌第一乳磨牙近中2个根管、远中2个根管牙齿占比最高为48.8%,左右侧根管数量及分布相同的比例为81.8%,不同性别患儿的根管分布差异有统计学意义(P<0.05); 不同性别患儿的根分叉处髓室顶、髓室底厚度及髓室高度差异均无统计学意义(P>0.05); 牛牙样牙发生率为4.72%。结论 本研究中福州地区下颌第一乳磨牙以近中2个根管、远中2个根管的类型最为常见,且多数患儿左右侧根管数量及分布情况相同。
Abstract:
Objective To analyze tooth hard tissue and pulp cavity morphology of primary mandibular first molar(PMFM)in children from Fuzhou region by cone beam CT(CBCT), and to provide reference for clinical treatment and oral related teaching and research work. Methods CBCT images of 119 pediatric patients were included, and tooth morphology was analyzed using software such as Mimics and 3-matic. Pulp cavity was reconstructed in three dimensional and the data were analyzed. The number and distribution of root canals, the height of the pulp chamber at the root bifurcation, and the thickness of the pulp chamber roof and floor were recorded. The gender differences in the above data were compared, and the incidence of taurodontism was analyzed statistically. Results The highest proportion of PMFM with two mesial and two distal root canals was 48.8%, and the proportion of teeth with the same number and distribution of left and right root canals was 81.8%. There were statistical differences in the number and distribution of root canals between different genders(P<0.05). There was no significant difference in the thickness of the roof and floor of pulp chamber and the height of the pulp chamber between different genders(P>0.05). The incidence of taurodontism was 4.72%. Conclusion In this study, the most common types of PMFM in Fuzhou region were two mesial and two distal root canals, and the number and distribution of left and right root canals were the same in most cases.
