摘　　要：目的:探讨NiTiflex K锉与ProTaper锉联合运用在细小钙化、弯曲根管预备的效果。方法:用ProTaper锉与NiTiflex K锉不同锥度,构建由大到小的顺序尖锥形逐步深入根管预备模式,共治疗85名患者,85颗未经治疗的后牙,每颗牙均有细小钙化、弯曲根管;所有根管均使用手用NiTiflex K锉与ProTaper锉相联合进行根管预备,评价临床疗效。结果:治疗85颗后牙,1例疏通不当引起侧穿,其余根管成形良好,无根管偏移、台阶、器械分离等并发症;所有患牙根管预备后术后反应轻。结论:NiTiflex K锉与ProTaper锉联合运用扩管模式预备细小钙化、弯曲根管,根管成形效果好,术后反应轻,不易折断。Objective： To study the feasibihy of NiTiflex K file combined with ProTaper file in the preparation of small, calcified and/ or curved root canals. Methods： A total of 85 patients with 85 posterior teeth with small calcified and/or curved root canals received initial endodontie treatment by a gradual descending order of tapered step-down mode in root canal preparation using NiTiflex K file combined with ProTaper file. The effects were clinically evaluated. Results： Except one root canal was lateral perforated for improper dredging, the remaining 84 posterior teeth demonstrated good root canal shape without transportation, ledge or instrument separation. The postoperative pain was light in all cases. Conclusion： The mode of NiTiflex K file combined with ProTaper file is feasible in the treatment of small calcified and/or curved root canals.
