摘　　要：目的观察应用Protaper手动镍钛锉和不锈钢K锉在慢性根尖周炎的一次性根管治疗术后的反应及远期疗效。方法将需要根管治疗的95例患者106颗磨牙随机分为Protaper手动锉组51颗牙和不锈钢K锉组55颗牙。分别进行Pmtaper手动锉和不锈钢K锉进行根管预备后，一次性根管充填。结果治疗后1～7dProtaper手动锉组术后反应率较不锈钢K锉组低（P〈0．05），远期疗效两组无明显差异（P〉0．05）。结论Protaper手动锉用于一次性根管治疗术后反应较少，疗效可靠。Objective To compare the postobturation of pain and the therapeutic effects of hand-used Ni-Ti ProTaper instrument and stainless steel K-files in single-visit root canal therapy.Methods 106 teeth were randomly divided into 2 groups. All teeth were treated with root canal therapy in single-visit. Hand-used Ni-Ti ProTaper instrument and stainless steel K-files were used respectively in treatment. Results The pain intensity of the first group was significantly lower than that of the second group within 1 - 7 days（ P 〈 0.05）. After 12 months, the efficiency rates of the two groups were not significantly different（ P 〉 0.05）. Conclusion Root canal therapy using hand-used Ni-Ti ProTaper instrument can significantly decrease postoperative pain.
