【摘要】 目的对两种常温流动根充封闭剂(硅酸钙基-iRoot SP、硅氧烷基-GuttaFlow2)结合单尖充填技术以及常用封闭剂(AH Plus)结合连续波热牙胶充填技术的短期临床效果进行评价。方法将279颗患牙(656个根管)随机分为3组,分别为iRoot SP组、GuttaFlow2组以及AH Plus组。记录每个根管的充填时间,拍数字化牙片评估每个根管的充填效果,并于术后1周及1月进行回访,记录患者的疼痛发生率。SPSS18.0对以上数据行统计学分析。结果 3组的根管充填效果均无统计学差异(P> 0.05);iRoot SP组与GuttaFlow2组的充填时间无显著差异(P> 0.05),较AH Plus组明显缩短(P <0.05);iRoot SP组与GuttaFlow2组的术后疼痛无统计学差异(P> 0.05),iRoot SP组与GuttaFlow2组均较AH Plus组疼痛发生率较低(P <0.05)。结论 GuttaFlow2和iRoot SP配合单尖充填技术较常用热牙胶充填技术节省填充时间,且能获得良好的临床效果,术后疼痛发生率较低。更多还原

【Abstract】 Objective The short-term clinical effects of two kinds of normal temperature flow root sealers(the calcium silicate-based sealer iRoot SP and the siloxane-based sealer GuttaFlow2) combined with single point filling technology and a frequently-used sealing agent(AH Plus) combined with continuous wave hot tooth filling technology were evaluated.Methods A total of 279 teeth(656 root canals) were randomly divided into three groups: the iRoot SP group,GuttaFlow2 group and AH plus group. We recorded the filling time of each root canal, collected a digital dental film to evaluate the filling effect of each root canal, and conducted a follow-up visit one week and one month after the operation to record the incidence of pain. We used SPSS 18.0 to analyze the above data.ResultsThere was no significant difference in the root canal filling effect among the three groups(P > 0.05). There was no significant difference in the filling time between the iRoot SP group and the GuttaFlow2 group(P > 0.05), but the filling time was significantly shorter in the AH Plus group(P < 0.05). There was no significant difference in the postoperative pain between the iRoot SP group and the GuttaFlow2 group(P > 0.05), and the incidence of pain in the iRoot SP group and the GuttaFlow2 group was lower than that in the AH Plus group(P < 0.05).Conclusions GuttaFlow2 and iRoot SP combined with single point filling technology can save filling time and obtain good clinical effects compared with frequently-used hot tooth filling technology and the incidence of postoperative pain was low.更多还原
