AIM The aim of this study was to test the effect of new protocol of glide path preparation by 20/0.04 rotary file on apical extrusion of debris when instrumenting fine curved mesial canals in mandibular molars with Self-adjusting File (SAF) and compare it to a glide path prepared by 20/0.02 hand K-file and rotary OneShape (OS) and reciprocating WaveOne (WO) file instrumentation. MATERIALS AND...

AIM To report on a conservative approach for removal of a fractured file in the severely curved apical portion of the distobuccal canal of a mandibular molar. SUMMARY With the assistance of stainless steel hand files and a chloroform-dipped gutta-percha cone, a fractured rotary NiTi instrument was successfully removed. The use of this technique may assist in removal of loose instrument fragme...

Background : The purpose of this study was to evaluate apical debris extrusion in curved root canals using a specific file system.METHODS:50 human mandibular molars were extracted and chosen for the study, ranging between 20 40 degree curvature radii <10mm randomly assigned 2 groups (n=20) according kinematics used canal preparation ( reciprocating motion with waveone gold system) Manual Tec...

Sixty moderately curved canals of mandibular molars classified as Vertucci’s type IV canal configuration were selected by micro-CT 1174. The teeth divided into two groups according to the kinematics used, whether reciprocating or rotary motion (n=30, totaling 60 mesial root canals). instruments used perform glide path procedures had identical features (0.15 mm tip size, 0.04 mm/mm taper, therma...

Rotary instrumentation has been proposed in undergraduate teaching. The aim of this study was to evaluate student’s performance, through the obturation quality and treatment time, a sequential range L-simulated root canals. A senior dental student sequentially prepared randomly numbered canals from 1 40, with WaveOne Gold glider primary file, according manufacturer instructions. gutta-percha co...
