INTRODUCTION The aim of this in vitro study was to evaluate the effects of establishing glide path on the centering ability and preparation time of two single-file reciprocating systems in mesial root canals of mandibular molars. METHODS AND MATERIALS Sixty extracted mandibular molars with curvatures of 25-39 degrees and separate foramina for the mesiobuccal and mesiolingual canals, were divi...

INTRODUCTION The purpose of this in vitro study was to compare the canal transportation and centering ability of Twisted File (TF) to that of Reciproc system. METHODS AND MATERIALS Forty noncalcified roots with mature apices, minimum length of 19 mm and an apical curvature of 15-30 degrees (according to Schneider's method), from freshly extracted mandibular and maxillary teeth, were selected ...

the aim of ideal canal preparation is to prevent iatrogenic aberrations such as transportation. the aim of this study was to evaluate the root canal transportation by reciproc file with and without glide path.thirty acrylic-resin blocks with a curvature of 60° and size#10 (2% taper) were assigned into two groups (n= 15). in group 1, the glide path was performed using stainless steel k-files siz...

WaveOne Gold, ProTaper Reciproc Blue, Next, and files were selected to compare the phase transformation behaviors mechanical properties of nickel-titanium (NiTi) rotary after gold heat blue treatments. The reverse finishing point temperatures Next higher than those other two instruments investigated. At a deflection 0.5 mm, loads significantly varied except for Gold. 3.0 Blue Gold compared ProT...
