Glide path is a procedure that precedes mechanical instrumentation of the root canals. It defined as used to expand or create smooth tunnel from coronal part canal its physiological terminus. performed using small sized hand files specially designed NiTi instruments. An adequately created glide extends life rotary instruments, enables better and chemical debridement easier preservation original...

OBJECTIVE 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. MATERIALS AND METHODS 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 performe...

Background. The present study aimed to compare the shaping ability of Reciproc Blue instruments with or without the creation of a glide path in simulated S-shaped root canals. Methods. Root canals of thirty #15.02 clear resin S-shaped blocks were dyed using ink and photographed. Then the blocks were randomly divided into 2 groups: group A: Reciproc Blue with glide path created with ProGlider an...

INTRODUCTION The purpose of this study was to evaluate and compare the volume of removed dentin, transportation, and centering ability of ProTaper Next (PTN) system with and without glide path preparation by using cone-beam computed tomography (CBCT) imaging. METHODS Sixty mesiobuccal canals of mandibular first molars with curvatures of 25°-35° were divided into 3 experimental groups (n = 20)...
