摘　　要：目的:通过CBCT图像进行牙髓三维重建及测量,评价牙周炎对牙髓体积和表面积的影响。方法:采用自身对照法,选取9名患者的24个同名牙(牙周炎患牙和牙周健康的对侧同名牙各12个)的CBCT影像资料,进行牙髓三维重建并对比分析二者牙髓的体积和表面积。结果:牙周炎组和健康组牙髓体积(mm^3)分别为22.61±11.80和26.03±14.14(P<0.05),表面积(mm^2)分别为66.62±27.81和76.52±35.46(P<0.05)。结论:牙周炎可导致牙髓体积和表面积减小。Objective:To evaluate the effects of periodontitis on the pulp volume and surface area.Methods:24 teeth from 9 patients were included(12 periodontitis teeth and 12 corresponding periodontally healthy teeth).3D reconstruction of dental pulp were conducted and the volume and surface area of the pulp were calculated with CBCT data.Paired t test was used to compare the pulp volume and surface area between the 2 groups.Results:The pulp volume(mm^3)of the teeth with periodontitis and the periodontally healthy teeth was 22.61±11.80 and 26.03±14.14(P<0.05),the pulp surface area(mm^2)was 66.62±27.81and 76.52±35.4(P<0.05),respectively.Conclusion:Periodontitis can reduce the volume and surface area of the dental pulp.
