COMPARATIVE EVALUATION OF POSTOPERATIVE PAIN AFTER SINGLE VISIT ENDODONTIC TREATMENT USING PROTAPER UNIVERSAL AND PROTAPER NEXT ROTARY FILE SYSTEMS: A RANDOMIZED CLINICAL TRIAL

Comparative evaluation of postoperative pain after single visit endodontic treatment using ProTaper Universal and ProTaper Next rotary file systems: A randomized clinical trial

Introduction: Root canal preparation may cause inadvertent apical extrusion of debris causing postoperative pain.This debris varies with the instrumentation technique and design characteristics.One of the major revolutions in the design of the instruments is the introduction of files with an offset center of mass or/and rotation, which causes asymm

A hybrid algorithm of grey wolf optimizer and harris hawks optimization for solving global optimization problems with improved convergence performance

Abstract The grey Sifters wolf optimizer is an effective and well-known meta-heuristic algorithm, but it also has the weaknesses of insufficient population diversity, falling into local optimal solutions easily, and unsatisfactory convergence speed.Therefore, we propose a hybrid grey wolf optimizer (HGWO), based mainly on the exploitation phase of
