Abstract
Objective:To compare the shaping ability of three NiTi instruments in simulated root canals.Methods:A total of 24 simulated resin blocks were divided randomly into 3 groups:WaveOne,ProTaper Next and TF Adaptive.Each group consisted of 8 root canals.The shaping time was measured.Pre-and post-shaping photographs were taken by precise camera and superimposed through Photoshop software.The dentin removed from the inner and outer canal walls at 9 points beginning at 0 mm from the foramen were measured with ImagePro Plus software.Centering ability was determined accordingly.Results:WaveOne was much faster than any other groups(P<0.05).At the apical curvature,transportation was the least with TF Adaptive,followed by Protaper Next(P<0.05).There were no significant differences in 3 groups with respect to coronal curvature transportation(P>0.05).Conclusion:Under the conditions of this study,WaveOne was the most efficient instrument.TF Adaptive and Protaper Next also showed good shaping ability.In general,all the instruments respected original canal curvature well and were safe to be used.关键词
