摘　　要：目的评价iRoot SP单尖法充填与iRoot SP热牙胶垂直加压充填法用于后牙窦道型慢性根尖周炎的临床疗效。方法选取2018年3月—2019年2月杭州师范大学附属医院口腔科收治的后牙窦道型慢性根尖周炎共100例,患者均为单颗牙患病;按照随机数字表法分为研究组和对照组,每组50颗,对照组患者采用iRoot SP热牙胶垂直加压法充填,研究组患者采用iRoot SP单尖法充填,比较2组患者术后1周疼痛反应情况,术后2周窦道愈合情况,术后3、6个月后根尖周阴影变化,治疗6个月后综合疗效评价。结果比较术后1周的疼痛反应,研究组与对照组疼痛反应率分别为24.0%、20.0%,差异无统计学意义(χ^(2)=0.233,P=0.629);术后2周窦道愈合率分别为96.0%、94.0%,研究组情况优于对照组,差异无统计学意义(χ^(2)=0.001,P>0.999);术后3个月根尖暗影情况比较,研究组及对照组有效率分别为100.0%、76.0%,差异有统计学意义(χ^(2)=13.636,P=0.001);术后6个月根尖暗影情况比较,研究组及对照组有效率分别为100.0%、96.0%,差异无统计学意义(χ^(2)=0.501,P=0.475)。术后6个月综合疗效评估,研究组与对照组治疗有效率分别为98.0%、96.0%,差异无统计学意义(χ^(2)<0.001,P>0.999)。结论 iRoot SP单尖法用于后牙窦道型慢性根尖周炎,临床操作方便,充填效率高,术后疼痛轻且成功率高,值得临床推广。Objective To evaluate the clinical efficacy of iRoot SP single-tip filling and iRoot SP warm vertical technique in patients with chronic apical periodontitis with sinus in posterior teeth. Methods A total of 100 posterior teeth diagnosed as chronic apical periodontitis with sinus were selected as research object from March 2018 to February 2019. According to the random number table, each group has 50 cases. The control group were treated with iRoot SP warm vertical technique and the study group were with iRoot SP single-tip filling. Pain rate 1 week after operation, sinus status 2 weeks after operation, apical shadow 3, 6 months after operation and 6 months follow-up of clinical effect were compared. Results Compared with the pain score at 1 week after operation, the response rates of the study group and the control group were 24.0% and 20.0%, respectively, with no significant difference(χ^(2)=0.233, P=0.629);the sinus healing rates at 2 weeks after operation were 96.0% and 94.0%, respectively, with no significant difference(χ^(2)=0.001, P>0.999);the effective rates of the study group and the control group at 3 months after operation were 100.0% and 76.0%, respectively, the difference was statistically significant(χ^(2)=13.636, P=0.001). Six months after operation, the effective rates of the study group and the control group were 100.0% and 96.0%, respectively, with no statistically significant difference(χ^(2)=0.501, P=0.475). Six months after operation, the comprehensive efficacy evaluation showed that the effective rates of the study group and the control group were 98.0% and 96.0%, respectively, with no statistically significant difference(χ^(2)<0.001, P>0.999). Conclusion iRoot SP single-tip method for chronic apical periodontitis patients is with high filling efficiency, ease of clinical operation, low incidence of postoperative pain and high treatment success rate, it is worthy of clinical promotion.
