Evaluation Of Apical Transportation Using 3 Different Rotary Systems: Hyflex Files, Twisted Files, Protaper Next By Morphometric Analysis

Aim: This in vitro study was performed to evaluate the apical transportation between Hyflex files, Twisted files and Protaper next single file rotary system by motic imaging. Materials & Methods: Sixty Endo Training Blocks were used in the study. Pre instrumentation photos of the simulated apical foramen are recorded using an optical microscope and then coupled into the motic imaging software and the position of the apical foramen was located. It was divided into three groups of twenty samples each and instrumented with Hyflex, Twisted and Protaper next rotary files. Irrigation was done with saline. Post instrumentation photos of the simulated apical foramen were recorded using the optical microscope and then coupled into the motic imaging software to locate the position of the apical foramen post instrumentation. Result: The minimum transportation was shown by the Hyflex rotary files (mean =31.18μm) followed by the Twisted rotary files (mean =41.67μm) and maximum transportation was seen in the Protaper next group (mean = 47.08μm).The intergroup difference was statistically significant(p<0.05).Conclusion: Hyflex files preserved the shape of the canal and the position of the apical foramen. It was followed by Twisted files. Maximum apical transportation was brought about by Protaper next files.
