摘　　要：目的:评价Guttaflow根管充填系统与热牙胶连续波技术对C型根管的充填效果。方法:将60枚具备C型根管的下颌后牙随机分为两组,每组30个样本。在对样本进行根管预备后,组1采用Gut-taflow根管充填系统充填,组2采用热牙胶连续波充填,分别对已经充填的离体牙在根方、根管中部、冠方进行水平方向切片,采用图像分析软件Image Plus Pro 6.0计算横截面中牙胶充填面积(GPFA),比较不同充填方式GPFA以及相同根管分类不同充填方法GPFA的差异。结果:Guttaflow组在冠、中、根方1/3的根管充填效果较热牙胶连续波技术好,差异均有统计学意义(P均<0.05);在Melton根管分类下,Guttaflow技术在C3、C4类型的C型根管中较热牙胶连续波技术具有更好的充填效果(P<0.05),但在C2类型根管中,Guttaflow与热牙胶连续波技术差异无统计学意义(P>0.05)。结论:Guttaflow根管充填系统对于C型根管具有良好的充填效果。Objective. To compare effect of continuous wave of condensation technique and Gutta-flow on C shaped root canal obturation. Methods= 60 mandibular molars with C-shaped root canal were collected, and randomly divided into 2 groups, with 30 teeth in each group. After root canal preparation, the root canals of each molar were then filled as followed= group 1. Guttaflow technique（GT）, 2： continuous wave of condensation technique （CW）. The percentage of gutta-percha-filled area （GPFA） at the apical, middle and coronal levels of each group was analyzed by Image Plus Pro 16.0 software. Results.Statistical differences of GPFA was found between 2 groups （Mann-Whitney U test, P〈O. 05）. GT group showed better filling ability than the CW group in C3, C4 type. No statistical differences was found between two groups in C2 type（Mann-Whitney U test, P〈0.05）. Conclusions： The Guttaflow system has better ability of root canal obturation than the continuous wave technique.
