It can also help in moving the coronal aspect of the canal away from the furcation.These studies included 4 research directions: cleaning efficacy of instrumentation, shaping ability of root canal preparation, mechanical properties of NiTi files, and clinical outcome of root canal therapy.

When there is a necessity to increase the taper of the coronal portion of the canal the SX file can be used with a brushing action. In cases where the apical portions of the canal are wide the following files can be included after the basic instrumentation sequence: S2 File is used to prepare the middle 1/3rd of the root canalį1 File is used to prepare the apical portion of the root canal S1 File is used to prepare the coronal 1/3rd of the root canal Most clinical cases can be completed using the following instrumentation sequence: Once working length is reached, the file should be withdrawn Use ProTaper rotary files at a constant and stable speed between 150 to 350 rpm The instruments are to be cleaned after use Irrigation is necessary before engaging the files ğinishing files – F1, F2, F3, F4 and F5Įxcluding the SX file all other files are available in lengths of 21 mm, 25 mm and 31 mm.įollowing working length determination and establishing a reproducible glide path, each instrument should be used progressively down to the working length.The following files are included in the ProTaper Universal System: Also, the non-cutting guiding tip reduces the possibility of accidental perforation of the floor of the pulp chamber or furcation. The file respects the root canal path better. The variable helix angle, non-cutting guiding tip and unique multiple taper design ensure better elimination of debris. The contact of the instrument with dentine is reduced to prevent screwing. The ProTaper files have a progressively tapered triangular cross section with a high cutting efficiency. The files have high cutting power and an apical taper for enhancing cleaning of the canals. The ProTaper system reduces chair time taken as only 3 instruments are required for most cases. Specifically designed drying (paper points) and obturation (gutta percha points) solutions are available, intended for use in canals shaped using the ProTaper Universal system. The files are colour coded for easy and instant identification and following the shaping protocol is relatively easy. Only one instrument sequence is required irrespective of the shape of the canal. They help the clinician carry out easy, fast and efficient root canal shaping procedures. The taper of ProTaper files can is variable throughout the cross section of the rotary file. The ProTaper rotary files speed and torque values have been specified by the manufacturer for maximum efficiency. Rotary ProTaper file system is a comprehensive endodontic file system that has been specially designed to meet the needs of clinicians. The ProTaper rotary files aid in efficient biomechanical preparation of the root canal. They are the ProTaper Shaping files and the ProTaper Finishing files. The ProTaper files are supplied as two variants to be used in different phases of shaping the root canals in endodontic therapy. Dentsply ProTaper Universal is a rotary endodontic file composed of nickel titanium alloy.
