Comparison of Canal Shaping and Transportation Between the Protaper Next and Protaper Ultimate in Simulated Double-curved Canals
Abstract
Aim: To compare the canal shaping and transportation caused by the Protaper Next (PTN) and Protaper Ultimate (PTU) file systems in artificially created double-curved canals. Material and Method: Thirty double-curved canals in clear resin blocks were prepared up to an apical size of #25 using PTN and PTU instruments. Resin blocks were filled with ink and photographed before and after instrumentation to develop composite images by superimposition. Shaping ability and transportation of the canals were evaluated. Student’s t-test and Mann Whitney U test was used (p
