Fatigue resistance decreased as the instrument diameter increased. The fatigue resistance of the instruments showed a tendency to decrease as the diameter of the instruments increased.Conclusions The bending moment at 45° and the torsional resistance of K3 instruments can be predicted using instrument diameter and cross-sectional area at 3 mm from the tip. Torque and bending moment of the tested instruments increased significantly with diameter and cross-sectional area at 3 mm from the instrument tip. Powered cleaning and shaping of root canals can be accomplished using either rotary or reciprocating files. Below is a review of different groups of instruments used in endodontics. ProTaper Next is an efficient 1 solution for endo practitioners seeking a versatile, flexible system that will handle the vast majority of root canal treatments. Endo files and endo reamers are instruments that are used for root canal preparation. The greater flexibility and unique swaggering movement of the ProTaper Next files mean greater versatility when shaping curved and narrow canals. A variety of endodontic instruments are available to achieve these goals. Fatigue resistance of instruments size 30, 0.04 taper, and sizes 20 and 25, 0.06 taper was determined in a fatigue test bench device.Results The analysed instruments presented no uniformity in the distance between adjacent blades, but the measured diameters at each millimetre from the tip were regular, showing compliance with manufacturing standards. The underlying approaches of root canal treatment include debridement, shaping, and sound filling of the root canal.

Maximum torque and angular deflection, as well as bending moment at 45° were measured according to specification of ISO 3630-1. The files were rotated with standard parameters 350 rpm and 2.5 Nmtorque using the Tri auto mini endomotor set.

10 taper) and a full set of ISO-sized NiTi rotary files, sizes 15 through 60, in.

The cross-sectional area at 3 mm from the tip of the same instruments was determined using digital image analysis of scanning electron microscopy images. Ten endodontic rotary files were selected in each of the two groups to be tested. The K3 system is comprised of two NiTi rotary orifice-openers (.08 and. Aim To correlate the mechanical behaviour in torsion, bending and fatigue tests of K3 instruments with their dimensional characteristics.Methodology Instrument length, tip angle, distance between blades (pitch length) and the diameter at each millimetre from the tip of sizes 20, 25 and 30, 0.04 taper and sizes 20 and 25, 0.06 taper K3 rotary instruments were measured in an optical microscope equipped with digital micrometers.
