Apical 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 کاملEvaluation of conventional, protaper hand and protaper rotary instrumentation system for apical extrusion of debris, irrigants and bacteria- An in vitro randomized trial
BACKGROUND Endodontic instrumentation carries the risk of over extrusion of debris and bacteria. The technique used and the type of instrumentation influences this risk. AIM The purpose of this study was to evaluate and compare the K-file, ProTaper hand and ProTaper rotary instrumentation systems for the amount of apically extruded debris, irrigant solution and intracanal bacteria. DESIGN E...
متن کاملEvaluation Of Apical Transportation Using 3 Different Rotary Systems: Hyflex Files, Twisted Files, Protaper Next By Morphometric Analysis
Aim: This in vitro study was performed to evaluate the apical transportation between Hyflex files, Twisted files and Protaper next single file rotary system by motic imaging. Materials & Methods: Sixty Endo Training Blocks were used in the study. Pre instrumentation photos of the simulated apical foramen are recorded using an optical microscope and then coupled into the motic imaging software a...
متن کاملSEM evaluation of canal wall dentine following use of Mtwo and ProTaper NiTi rotary instruments.
AIM To compare using scanning electron microscopy (SEM) root canal walls following instrumentation in vitro with two different rotary NiTi instruments. The hypothesis was that no difference should be observable between the experimental groups in terms of debris on canal walls and surface morphology. METHODOLOGY Twenty-four single-rooted human teeth were selected. Two types of NiTi instruments...
متن کاملCanal Centring Ability of ProTaper and Mtwo Rotary Systems in Curved Canals
The purpose of this investigation was to compare centring ratio of ProTaper and Mtwo rotary systems. 60 mandibular molar teeth which had 25, 30 and 35 degree curvature in mesio-buccal root canal were used. Group 1 had 25°, Group 2 had 30°, and Group 3 had 35° curvatures. The roots were sectioned horizontally at 2 mm away from the apex. The apical region was then observed under a stereo-microsco...
