摘　　要：目的:旨在探讨两步法根管预备和常规一次根管预备对于根管治疗期间急症的影响效果。方法:选择120例慢性根尖周炎患者,随机分为两组,采用两种方法进行根管预备,观察术后急症的发生率。结果:共19例患牙发生根管治疗诊间急症,其中常规根管预备组15牙(19%)、两步法根管预备组4牙(5.5%),两组比较有显著性差异(P<0.05)。两步法根管预备的总有效率为94.5%,常规根管预备组为81%,两组差异显著(P<0.05)。结论:两步法根管预备可以减少术后肿胀等临床急症,临床应用前景广阔。Objective To determine the effect of adopting two step Root canal preparation preventing from endodontic interappointment emergencies. Methods 120 cases of chronic periapical periodontitis, pulp necrosis, remaining root and remaining crowns that needed to treat the root canal were divided in two groups randomly.One group used two step Root canal preparation,the control group used one step Root canal preparation.Each group had60 samples. Results Acute disease incidence in experimental groups was 23.3%, obviously lower than40% in control group. Conclusion Two step-Root canal preparation can effectively prevent endodontic interappomtment emergencies.
