Mani Flare Files are nickel titanium hand files used to shape the root canal in endodontic procedures. The NiTi files by Mani have a unique 5% taper and a triangular cross-section. The flare files undergo patented thermal processing which provides them desirable physical properties such as flexibility, sharpness and efficiency. The Niti k files are very effective for curved canals. Mani Flare Files reduce the number of instruments needed when compared to the conventional step back preparation of the root canal.
