摘要
目的:利用CBCT测量分析乳牙牙冠硬组织厚度。方法:收集6岁以下接受CBCT检查儿童的47例影像学资料,通过MIMICS软件进行乳牙牙冠硬组织厚度的测量,应用SPSS 22.0进行数据分析。结果:乳牙牙冠硬组织中,除上颌乳中切牙唇面及下颌第一乳磨牙远中邻面外,近中邻面的平均厚度最小(P<0.01)。对上下颌同名牙比较,乳前牙中,除了乳尖牙唇侧,上颌厚度均显著大于下颌(P<0.01)。上颌乳磨牙的远中及舌/腭侧厚度大于下颌,颊侧厚度小于下颌(P<0.01)。结论:乳牙牙冠硬组织厚度在不同牙位分布存在不同程度的差异。
Objective:To analyze the hard tissue thickness in the crown of primary teeth by CBCT.Methods:The CBCT imaging data of 47 children were included,and the hard tissue thickness of primary teeth was measured by MIMICS software.SPSS 22.0 was used for data analysis.Results:The average thickness in the mesial surfaces was the smallest(P<0.01),except for the libial surface of maxillary central incisor and the distal surface of mandibular first primary molar.In primary anteriors,the thickness in the same surface of maxillary teeth was greater than that of mandibular teeth significantly(P<0.01)except for the libial surface of primary canine.In primary molars,the thickness of hard tissue in the same part of the distal and lingual side of the maxillary teeth was greater than that of the mandibular teeth(P<0.01),and the thickness in the buccal side of maxillary teeth was lower than that of the mandibular teeth(P<0.01).Conclusion:The distribution of hard tissue thickness of primary teeth in different position is different.
