摘　　要：目的:研究急性根尖周炎首诊封药后疼痛的缓解情况,为急性根尖周炎的首诊治疗提供临床参考。方法:单根管急性根尖周炎患牙303例,随机分为A组(根管开放组101例)、B组(标准法"H"锉预备封药组99例)、C组(冠下法、大锥度镍钛锉预备封药组103例),A组常规开髓拔髓、根管简单清创后开放;B组使用"H"挫预备后封樟脑酚;C组采用大锥度旋转镍钛锉预备、超声荡洗等现代根管治疗技术和药物首诊完成根管的机械化学预备并封氢氧化钙,观察各组治疗后疼痛的缓解情况。结果:A组疼痛不缓解的发生率为1.0%,B组19.2%,C组8.7%,3组间均有显著性差异(P<0.05)。结论:大锥度镍钛旋转器械、超声器械、氢氧化钙的使用可显著降低急性根尖周炎首诊封药后疼痛的发生率。Objective：To evaluate the incidence pain after treatment of acute periapical periodontitis using calcium hydroxide and CP as an intracanal dressing at the first time.Methods：303 patients with single-root acute periapical periodontitis were randoml allocated to three groups.A group was treated by stainless steel hand files and opened;B group was treated by stainless steel hand files and covered by CP.;C group was treated with Hero nickel-titanium rotary instruments and covered by calcium hydroxide paste.The incidence and degree of incidence pain after root canal preparation in the three groups were recorded.Results：There were significant difference between group A and group B,group B and group C,group A and group C（P0.05）.Conclusion：Nickel-titanium rotary instruments and calcium hydroxide paste used can effectively prevent and reduce the pain and dropsy during root canal therapy on acute periapical periodontitis.
