HyFlex、S3、K3XF以及ProTaper在树脂模拟根管中成形能力的比较研究
Comparative evaluation of shaping ability of HyFlex, S3, K3XF and ProTaper in simulated curved canals
摘要
Abstract
Objective To compare the shaping ability of HyFlex, S3, K3XF and ProTaper in simulated resin canals. Methods Forty curved artificial root canals in resin blocks were divided into four groups randomly, and prepared to an apical using HyFlex, S3, K3XF and ProTaper, respectively. Images of pre- and post-instrumentation were superimposed by Photoshop CS5. Incidence of instrument fracture was recorded. The amount of resin removed by each system was measured at 10 measuring points by AutoCAD 2010. The data were analyzed by using one-way analysis of variance. Results One case of instrument fracture occurred in S3, K3XF and ProTaper respectively. The centering ability of HyFlex was the best at 2 mm to 3 mm from the apex(P<0.05). At 4 mm to 6 mm levels, K3XF showed a significantly higher centering ability(P<0.05). Conclusion The four systems could maintain the original canal morphology well without obvious canal transportation and ledging. In the apical of the root canal, the shaping ability of HyFlex was the best compared with others, whereas K3XF seemed to have more advantages in the middle.关键词
