In the present study, GTX and ProTaper as continuous rotating endodontic files were numerically compared with WaveOne reciprocating file using finite element analysis, aiming at having a low cost, accurate/trustworthy comparison as well as finding out the effect of instrument design and manufacturing material on its lifespan. Two 3D finite element models were especially prepared for this compar...

Objective To evaluate transportation (T) and centering ability (CA) of root canal preparations using continuous or reciprocating nickel-titanium endodontic files. Materials and Methods Ninety-six mesiobuccal root canals of mandibular first and second molars were randomly divided into 6 groups (n=16) according to the rotary file used: 1. ProTaper Next; 2. ProTaper Gold; 3. Mtwo; 4. BioRaCe; 5....

INTRODUCTION The objective of the present study was to clinically compare the incidence of postoperative pain and the intake of analgesic medication (frequency and quantity) after endodontic treatment of posterior teeth using 2 reciprocating systems and a continuous rotary system. METHODS In a prospective randomized clinical study, 210 patients with vital teeth indicated for conventional endo...

AIM To compare the bacterial reduction achieved with reciprocating and rotary systems during root canal preparation. METHODOLOGY Sixty distobuccal root canals of maxillary molars were contaminated with Enterococcus faecalis broth culture. After an incubation period of 21 days, bacterial samples were collected and cultured on m-Enterococcus agar plates. The root canals were divided into five g...
