ProTaper rotary root canal preparation: assessment of torque and force in relation to canal anatomy.
AIM To investigate physical parameters for ProTaper nickel-titanium (NiTi) rotary instruments whilst preparing curved canals in maxillary molars in vitro. METHODOLOGY A novel torque-testing platform was used to prepare root canals in 15 extracted human maxillary molars with ProTaper rotary instruments. Peak torque and force was registered along with numbers of rotations required to shape the ...
متن کاملIn vitro assessment of torque and force generated by novel ProTaper Next Instruments during simulated canal preparation.
INTRODUCTION The purpose of this study was to assess torque and force for simulated canal preparation with a new root canal instrument, ProTaper Next. METHODS Six sets of ProTaper Next Instruments (X1-X5) were used to prepare 36 artificial canals. Files were divided into 6 groups. Different settings of rotations per minute (250, 300, and 350 rpm) and numbers of in-and-out movements to reach w...
متن کاملThe failures of root canal preparation with hand ProTaper
UNLABELLED The failures of root canal preparation are due to some anatomical deviation (canal in "C" or "S") and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. OBJECTIVES Our study was made on technique errors while preparing the canal roots with hand ProTaper. METHODO...
متن کاملThe effect of root canal preparation on the surface roughness of WaveOne and WaveOne Gold files: atomic force microscopy study
Objectives To examine the surface topography of intact WaveOne (WO; Dentsply Sirona Endodontics) and WaveOne Gold (WOG; Dentsply Sirona Endodontics) nickel-titanium rotary files and to evaluate the presence of alterations to the surface topography after root canal preparations of severely curved root canals in molar teeth. Materials and Methods Forty-eight severely curved canals of extracted ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
