A Stereomicroscopic Evaluation of Dentinal Cracks at Different Instrumentation Lengths by Using Different Rotary Files (ProTaper Universal, ProTaper Next, and HyFlex CM): An Ex Vivo Study
Introduction. The aim of the present study was to evaluate the dentinal cracks after root canal preparation with rotary files: Gates Glidden, ProTaper Universal, ProTaper Next, and HyFlex CM at different instrumentation lengths. Methodology. Sixty-five mandibular premolars were mounted in the acrylic tube with simulated periodontal ligaments and the apex was exposed. The root canals were instru...
متن کاملAssessment of cleaning efficacy of Mtwo NiTi rotary files and Hand K-files: A comparative in-vitro study
NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...
متن کاملChemomechanical preparation by hand instrumentation and by Mtwo engine-driven rotary files, an ex vivo study
OBJECTIVE To compare the disinfecting efficacy of the sodium hypochlorite irrigation by root canal preparation with stainless steel hand files, taper 0.02 and nickel-titanium Mtwo files with taper 0.04-0.06. STUDY DESIGN 40 extracted human teeth were sterilized, and then inoculated with Enterococcus faecalis (ATCC 29212). After 6 day incubation time the root canals were prepared by hand with ...
متن کاملExtended apical enlargement with hand files versus rotary NiTi files. Part II.
OBJECTIVE The objective of this study was to compare 2 preparation techniques performed under simulated clinical conditions with extended apical enlargement following determination of the optimal apical preparation size (APS). STUDY DESIGN After preflaring 240 root canals, APS was evaluated as outlined in Part I. The apical portion was shaped to APS either with rotary NiTi Lightspeed instrume...
متن کاملA COMPARISON OF Ni-Ti ROTARY AND HAND FILES INSTRUMENTATION IN PRIMARY MOLARS
The aim of the study was to compare the manual and rotary endodontic instruments focusing on risk of perforation when the whole root canal length is instrumented as well as the time required for preparation in primary teeth Fifty four teeth were divided randomly into three groups.Group I: The root canals were prepared manually with K-files. Group II : ProTaper instruments were used in a crown-d...
