Resistance to fracture of teeth instrumented using novel EndoStar E5 rotary versus ProTaper NEXT and WaveOne file systems
Aim The current study compared the fracture resistance of samples instrumented by two rotary files and a reciprocating file, obturated with gutta-percha and AH Plus. Materials and Methods A total of 60 freshly extracted mandibular premolar teeth with single roots and single canals were acquired and decoronated at or below the cementoenamel junction. The samples were randomly divided into four...
متن کاملFracture resistance of lithium disilicate restorations after endodontic access preparation: An in vitro study.
STATEMENT OF PROBLEM Endodontic access preparation through a lithium disilicate restoration is a frequently encountered clinical situation. The common practice of repairing the accessed crown with composite resin may result in a weakened restoration. PURPOSE The purpose of this in vitro study was to determine the effect of endodontic access preparation on the fracture resistance and microstru...
متن کاملA Comparative Study of ProTaper Universal and ProTaper Next Used by Undergraduate Students to Prepare Root Canals.
INTRODUCTION The purpose of this study was to determine whether final-year undergraduate dental students achieved better shaping outcomes using the new ProTaper Next (PTN; Dentsply Sirona, Ballaigues, Switzerland) system to prepare root canals for the first time compared with the existing ProTaper Universal (PTU, Dentsply Sirona) system on which they had trained. A secondary aim was to explore ...
متن کاملDifferences in cyclic fatigue resistance between ProTaper Next and ProTaper Universal instruments at different levels.
INTRODUCTION New designs and alloys have been developed to increase cyclic fatigue (CF) resistance of rotary files. The aim of this study was to compare CF resistance of ProTaper Universal (PTU; Dentsply Tulsa Dental, Tulsa, OK) and ProTaper Next (PTN, Dentsply Tulsa Dental) instruments at different points of curvature. METHODS A total of 420 files (240 PTU, S1, F1, F2, and F3 and 180 PTN, X1...
متن کاملA comparative evaluation of fracture resistance of endodontically treated teeth restored with different post core systems - an in-vitro study
PURPOSE To compare the fracture resistance and the mode of failure of endodontically treated teeth restored with different post-core systems. MATERIALS AND METHODS Root canal treatment was performed on 40 maxillary incisors and the samples were divided into four groups of 10 each. For three experimental groups post space preparation was done and teeth were restored with cast post-core (Group ...
