目的：本实验室研究的目的是比较XP Shaper（FKG Dentaire SA，La Chaux-de-Fonds，瑞士）和OneCurve（Micro-Mega，贝桑松，法国）系统在狭窄canals.Methods成形过程中形成的成形力和扭矩：将单根管的下颌前磨牙平均分为两组; XP Shaper和OneCurve（n=16）。在两组中，使用XP Shaper锉（30/01）或OneCurve锉（25/06）进行根管成形，插入3次，直至达到根管长度。在整个实验过程中，在受控的模拟根管内温度下，将牙齿包围在水中。记录向内和向外的峰值力和峰值扭矩，并使用Mann-Whitney检验进行统计学分析。使用Student t检验分析成形时间。结果：两组患者在两个方向上产生的力和扭矩均随着锉的插入次数的增加而增加。在两组中，向内峰值力范围为0.33 - 3.12 N，而向外峰值力范围为0.09 - 1.96 N。在三次插入中，XP塑形器在两个方向上的峰值力均显著较低。两组中产生的峰值扭矩范围为0.12 - 1.52 N.cm。XP Shaper在所有插入中的扭矩值均显著低于OneCurve。XP Shaper系统能在33.4秒内完成根管成形，而OneCurve系统能在32.8秒内完成根管成形。结论：XP Shaper系统在根管成形过程中表现出更低的力和扭矩值。
Objective: The purpose of this laboratory-based study was to compare the shaping forces and torques developed by the XP Shaper (FKG Dentaire SA, La Chaux-de-fonds, Switzerland) and OneCurve (Micro-Mega, Besancon, France) systems during shaping of narrow canals.Methods: Mandibular premolars with a single canal were divided equally into two groups; XP Shaper and OneCurve (n=16 each). In both groups, the canals were shaped with XP Shaper file (30/01) or OneCurve file (25/O6) that was inserted three times until it reached the canal length. The tooth was surrounded by water under controlled simulated intracanal temperature throughout the experiment. The inward and outward peak forces and the peak torques were recorded and analyzed statistically using the Mann-Whitney test. The shaping times were analyzed using Student's t-test. The significance level was set at 5%.Results: In both groups, the developed forces in both directions and the torques increased with the successive insertions of the file. In the two groups, the inward peak forces ranged from 0.33 to 3.12 N, while the outward peak forces ranged from 0.09 to 1.96 N. In the three insertions, the XP Shaper showed significantly lower peak forces in both directions. The peak torque developed in both groups ranged from 0.12 to 1.52 N.cm. XP Shaper had significantly lower torque values in all the insertions than OneCurve. The XP Shaper system was able to completely shape the canals in 33.4 seconds while the OneCurve system was able to completely shape the canals in 32.8 seconds.Conclusion: The XP Shaper system showed favorably lower force and torque values during canal shaping compared with the OneCurve system.
