Quizplus · Accepted Answer

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 reamer is used to cut, smooth, and enlarge the inner wall of the canal. 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. The Gates Glidden bur or drill is used to open the canal orifice and enlarge the walls of the pulp chamber.
