Evaluation of the Apical Seal in Root Canals Prepared with Rotary ProTaper Files and Obturated by Different Methods

Comparative evaluation of fracture and defect in reciproc and rotary files in severe curved root canals

Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...

"In vitro" evaluation of the apical sealing of root canals obturated with different techniques.

The purpose of this study was to compare the apical sealing of root canals obturated with different techniques. One hundred-six human mandibular incisors were submitted to instrumentation by means of the step-back technique. After instrumentation, one hundred teeth received an impermeable coating on the external surfaces of the crown and root (except for the area nearby the apical foramen). Aft...

Cone-beam computed tomography evaluation of curved root canals prepared using reciprocal rotary files and rotational rotary files

Aim The aim of this study is to compare curved root canal preparation between reciprocal rotary files and rotational rotary files in extracted teeth using cone-beam computed tomography (CBCT). The independent variable was the file type (reciprocal vs. rotary), and the primary outcome variable was the centering ratio of distance change after canal preparation. Secondary outcomes were canal trans...

In vitro evaluation of root canals obturated with four different techniques. Part 2: apical leakage.

Remaining dentine thickness of root canals prepared with K-3 and ProTaper rotary systems.

OBJECTIVE To compare the remaining dentine thickness of root canals prepared with K-3 and ProTaper files.. METHODS This in-vitro experimental study was conducted from 1st April-30th September 2015 at the dental clinics of Aga Khan University Hospital, Karachi, and comprised human teeth. Extracted human premolars and molars were included in the study using non-probability consecutive sampling....
