Shaping ability of Wave One, One Shape, Hyflex CM and Trushape 3D Nickel Titanium Rotary Instruments with Different Access Angles

Mohammed Hameed, Noor Nadhum

Abstract: This study was performed to detect the shaping ability of Wave one, One shape, Hyflex CM and Trushape 3D Nickel Titanium Rotary instruments with different access angles in the L-shape stimulated canal blocks. these blocks were divided into four groups of thirty each (0 0, +450and -450access angles ( ten sample for each access angle). Each instrument was used according to the manufacturers? instruction. Pre- and postoperative images of the simulated canals were taken under standardized mannersby using a stereomicroscop. The pre- and postoperative images were superimposed into a composite image using a computer software program (Adobe Photoshop 7 ME). The first measuring point was 1 mm away from the artificial apical foramen, and the last measuring point was 10 mm from the apical end, resulting in 10 measuring points on the inner and outer sides of the canal, The data were statistically analyzed with ANOVA test and Turkey's honest significant difference test. The results of this study reveled that instrumentation by Trushape file) is statistically significant less canal centering value as compared with all other groups of this studyat most measuring points, while group instrumented by Hyflex file has statistically significant less canal centering value as compared with other groups at all measuring points. Also the results showed that 00 access angle has less canal centering values than with ( +450 and -450) access anglesin most instrument types of this study. The results of this study reveled that the canal transportation of group instrumented by Wave one file has statistically significant differences as compared with other groups at most measuring points. Also there was statistical significant differences less canal transportation in groups with (00) access angle as compared groups with (+450 and -450) access angles. Also the results showed that the groups with (+450) access angle has statistical significant less canal transportation as compared with groups with (-450) access angle. at most measuring points.
