A Stereomicroscopic Evaluation of Dentinal Cracks at Different Instrumentation Lengths by Using Different Rotary Files (ProTaper Universal, ProTaper Next, and HyFlex CM): An Ex Vivo Study
Introduction. The aim of the present study was to evaluate the dentinal cracks after root canal preparation with rotary files: Gates Glidden, ProTaper Universal, ProTaper Next, and HyFlex CM at different instrumentation lengths. Methodology. Sixty-five mandibular premolars were mounted in the acrylic tube with simulated periodontal ligaments and the apex was exposed. The root canals were instru...
متن کاملStereomicroscopic Evaluation of Radicular Dentinal Defects after Using EDTA Gel with Different Rotary Systems: An In-Vitro Study
The purpose of the present study was to study the occurrence of radicular dentinal defects after using EDTA gel during preparation of the root canal with ProTaper Universal (Dentsply Maillefer, Switzerland), HyFlex (ColteneWhaledent, Allstetten, Switzerland), and ProTaper Next (Dentsply Maillefer) rotary instruments. Forty-eight single rooted premolars were selected. Twelve teeth were instrumen...
متن کاملInfluence of a glide path on the dentinal crack formation of ProTaper Next system.
OBJECTIVES The aim was to evaluate dentinal crack formation after root canal preparation with ProTaper Next system (PTN) with and without a glide path. MATERIALS AND METHODS Forty-five mesial roots of mandibular first molars were selected. Fifteen teeth were left unprepared and served as controls. The experimental groups consist of mesiobuccal and mesiolingual root canals of remaining 30 teet...
متن کاملApical extrusion of debris using ProTaper Universal and ProTaper Next rotary systems.
AIM To assess and compare the amount of extruded debris after canal preparation using ProTaper Universal and ProTaper Next files. METHODOLOGY Forty extracted mandibular premolars with single canals and of similar lengths were instrumented using the ProTaper Universal F3 or the ProTaper Next X3. The extruded debris during instrumentation was collected into pre-weighed Eppendorf tubes. The tube...
متن کاملVertical Root Fracture initiation in curved roots after root canal preparation: A dentinal micro-crack analysis with LED transillumination
Background One of the causative factors of root defects is the increased friction produced by rotary instrumentation. A high canal curvature may increase stress, making the tooth more susceptible to dentinal cracks. The purpose of this study was to evaluate dentinal micro-crack formation with the ProTaper NEXT and ProTaper Universal systems using LED transillumination, and to analyze the micro-...
