摘　　要：目的 探讨CBCT联合热牙胶技术治疗下颌第二磨牙C形根管的临床疗效分析。方法 选取2015年1月至2020年1月南京大学医学院附属口腔医牙体牙髓科就诊的下颌第二磨牙被诊断为C形根管需要做根管治疗的患者50例(50颗),按随机数字表法分为常规组和干预组,各25例(25颗)。两组术前术后均采用CBCT检测,常规组采用冷牙胶侧压根充治疗,干预组采用热牙胶垂直加压填充,观察根管填充质量、疗效、并发症等相关性分析。结果 两组根管填充质量中恰填和欠填率比较,差异有统计学意义(P<0.05),干预组恰填率高于常规组,而干预组欠填率低于常规组;两组超填率比较,差异无统计学意义(P>0.05);两组总有效率比较,差异有统计学意义(χ^(2)=4.072,P=0.043),两组根管填充时间和填充材料与根尖区的距离比较,差异有统计学意义(P<0.05),干预组根管填充时间少于常规组,干预组材料与根尖区的距离短于常规组;两组治疗并发症发生率比较,差异有统计学意义(P<0.05),干预组低于常规组;干预组术后3个月有2例(8.00%)患者出现根尖周病变,常规组有6例(24.00%)出现根尖周病变,两组复发率比较,差异有统计学意义(χ^(2)=8.000,P=0.005)。结论 CBCT联合热牙胶技术能够有效提高下颌第二磨牙C形根管填充质量,改善患者临床症状,减少填充时间、术后疼痛、肿胀及复发,值得临床应用。Objective Observe the effect of CBCT combined with hot tooth glue technology on the C-shaped root canal of mandibular second molar. Methods Fifty patients(50) were selected for the mandibular second molar that was diagnosed as a C-shaped root canal from January 2015 to January 2020. The random number table method is divided into a routine group and an intervention group, with 25 cases(25 tablets) each. Both groups were examined by CBCT before and after surgery. The conventional group was treated with cold tooth gum lateral pressure root filling treatment, and the intervention group was heated with hot tooth gum vertical compression filling to observe the correlation analysis of root canal filling quality, curative effect, complications and so on. Results There was a statistically significant difference between the exact filling rate and the underfill rate in the root canal filling quality of the two groups(P<0.05). The exact filling rate in the intervention group was higher than that in the conventional group, while the underfill rate in the intervention group was lower than the conventional group;There was no statistically significant difference in overfill rate between the two groups(P>0.05);The total effective rate between the two groups was statistically significant(χ2=4.072, P=0.043). Comparison of root canal filling time and distance between filling material and apical area the difference in the distance between the regions was statistically significant(P<0.05). The root canal filling time of the intervention group was less than that of the conventional group, and the distance between the materials of the intervention group and the apical region was shorter than that of the conventional group. The difference was statistically significant(P<0.05). The intervention group was lower than the conventional group;2 patients(8.00%) had periapical lesions 3 months after the intervention group, and 6 patients(24.00%) had roots in the conventional group For periapical lesions, the recurrence rate between the two grou
