To evaluate the clinical effects of GuttaFlow on root canal obturation.
314 teeth were divided into 2 groups randomly.The GuttaFlow plus gutta-percha cone was used to fill root canals in the experimental group and Endomenthasone sealer plus gutta-percha cone was used in the control group. The filling time, the effect of root canal obturation by X-ray, the occurrence of pain during the filling operation and after treatment were recorded. The data was analyzed with SPSS13.0 software package.
The filling time in the experimental group was significantly less than that in the control group by rank sum test (P<0.01).There was no significant difference between the two groups on both the root filling effect and occurrence of pain by Chi-square test (P>0.05).
The root canal obturation of GuttaFlow plus gutta-percha cone is an easier and faster filling system for root canals. There is no significant difference on root filling effect and occurrence of pain between the GuttaFlow and the normal lateral compaction technique. It is one choice of clinical techniques for root canal obturation.
评估GuttaFlow用于根管充填的临床效果。
将314颗牙齿随机分为2组。实验组采用GuttaFlow加牙胶尖进行根管充填，对照组采用Endomenthasone封闭剂加牙胶尖进行根管充填。记录充填时间、X线片显示的根管充填效果、充填操作过程中及治疗后疼痛的发生情况。采用SPSS13.0软件包对数据进行分析。
秩和检验显示，实验组的充填时间显著少于对照组（P<0.01）。卡方检验表明，两组在根管充填效果和疼痛发生情况方面均无显著差异（P>0.05）。
GuttaFlow加牙胶尖进行根管充填是一种更简便、快速的根管充填系统。GuttaFlow与传统侧方加压技术在根管充填效果和疼痛发生情况上无显著差异。它是根管充填临床技术的一种选择。
