The Gates Glidden bur attaches to a slow-speed contra-angle handpiece and is used to open the canal orifice and enlarge the walls of the pulp chamber. The reamer is used to cut, smooth, and enlarge the inner wall of the canal. The Peso file prepares the canal for an endodontic post by removing a portion of the gutta-percha sealed in the canal to make room. The K-type endodontic file is used to clean and contour the inner wall of the canal. A Lentulo spiral file places the endodontic sealer or cement in the canal for the final seal prior to the placement of gutta-percha.
