摘　　要：目的：评价往复运动式Reciproc单支锉预备磨牙弯曲根管，保持原根管解剖走向的能力。方法选择年龄18～59岁牙髓病初诊病例，按 Schneider 测量法，第一磨牙弯曲根管（20°～30°）100例，200个根管（颊，舌弯曲根管），随机分为Reciproc组50例，100个根管，Protaper组50例，100个根管，进行根管预备。测量术前片、插针片、主尖片的根管弯曲度，比较根管偏移率，评价根管成形和根尖封闭效果。结果2组机用镍钛锉备根成功率：Reciproc组99％，Protaper组92％，有显著性差异（ P＜0．05）。结论 Reciproc的创新设计，使预备磨牙弯曲根管成形佳，反应轻，根尖封闭好，快捷高效，实现了一支锉代替一组锉。Objective To evaluate the ability to keep the original root canal anatomy flow by Reciproc single file in preparing molar curved root canals. Methods Patients aged from 18 to 59 years old who were newly diagnosed with pulp disease were selected. Ac-cording to Schneider measurement, 100 first molar curved root canals （20°~30°） and 200 canals （cheek, tongue curved root canals） were randomly divided into Reciproc group of 50 cases with 100 canals, and Protaper group of 50 cases with 100 canals. Then root ca-nals were prepared, followed by the measurement of root canal curvature of the dental film chip in first root canal file, the final root ca-nal file, and the trial point root canal file. The apical transportation of root canals in two groups were compared, and the effects of root canal formation as well as root tip closure were evaluated. Results Success rate in Reciproc group was 99%, while success rate in Protaper group was 92%, and the difference was significant （ P〈0.05） . Conclusion With its innovative design, the Reciproc single file enables the preparation molar curved root canals to have fine formation, light reaction, good closure in the apex, quickness and high efficiency, making a single file take place of a set of files.
