摘　　要：目的:探讨GuttaFlow~ 2常温流动牙胶在后牙急性牙髓炎一次性根管治疗中的疗效,为更高效、更舒适、更简单的治疗提供依据。方法:选取90颗后牙随机分为2组,A组45颗以GuttaFlow~ 2常温流动牙胶配合主尖行单尖法一次性根管治疗,B组45颗以i Root SP配合主尖做一次性热牙胶充填。对A、B组治疗时间,以及治疗后24 h、3 d、7 d、1个月、3个月疼痛指数与治疗有效率进行对比,用统计学方法比较两者差异。结果:在治疗操作时间上,A组为(63.20±6.54)min,B组为(86.12±8.08)min,A组明显优于B组(P<0.01)。A、B 2组疼痛指数在治疗后24 h分别为(2.40±0.54)和(4.60±1.31),治疗后3 d分别为(1.80±0.63)和(3.10±1.23),差异具有统计学意义(P<0.05);而治疗7 d、1个月、3个月后均无明显差异(P>0.05);A、B两组治疗有效率在各时间点均无明显差异(P>0.05)。结论:GuttaFlow~ 2常温流动牙胶在单尖法一次性根管治疗中具有很好的治疗效果,相比热牙胶充填有着其独特优势,可普遍用于一次性后牙根管治疗,同时也给专科医生提供了新思路,为大家自主创新提供了参考。Objective：To study the treatment effect of one-visit root canal therapy for molar acute pulpitis using GuttaFlow~ 2,thus to provide a more efficient,comfortable way and lay a basis for simpler treatment. Methods：Totally 90 molar teeth were selected and divided into two groups,45 teeth in A group used GuttaFlow~ 2 plus single cone obturation treatment,45 teeth in B group used i Root SP plus thermoplasticized gutta-percha technique. The treatment time,and the difference of pain index and efficiency between two groups after 24 hours,3 days,7 days,one month and three months were compared. Results：Concerning the treatment operation time,the group A was（63.20±6.54）min,while the group B was（86.12±8.08）min,the group A was significantly better than the group B（P〈0.01）. The pain index of group A and group B was（2.40±0.54）and（4.60±1.31）at 24 hours after treatment,and（1.80±0.63） and（3.10 ±1.23） after 3 days respectively,and the difference was statistically significant（P〈0.05）. There was a significant difference between the two groups in pain index after 24 h and 3 days（P〈0.05）,but no significant difference after 7 days,one month and 3 months（P〈0.05）. There was no significant difference in the efficiency at each time point（P〈0.05）. Conclusion：GuttaFlow~ 2 non-heated flowable gutta-percha has a good therapeutic effect in the treatment of one-visit root canal therapy and has its unique advantage. It can be widely used in one-visit root canal therapy in molars compared with hot gum filling. It also provides a new idea for independent innovation.
