Endodontic rotary file systems9/27/2023 ![]() Effects of three nickel titanium instrument systems on root canal geometry assessed by micro-computed tomography. Gergi R, Osta N, Bourbouze G, Zgheib C, Arbab-Chirani R, Naaman A.(4)Īt this time, there is no scientific evidence to suggest whether one system is more advantageous over another. There is an increased possibility of vertical root fracture using this procedure if excessive pressure is applied against the canal walls. In this technique, gutta-percha cones are placed within the canal and finger spreaders are used to place filling material and pack the canal space. Currently, carriers made of cross-linked gutta-percha such as Gutta-Core ( Tulsa/Dentsply) are available which may be easier to remove from the canal in situations where retreatment is necessary. Different carrier-based systems use different core materials to deliver gutta-percha to the canals. This is a popular option used to fill canal spaces. Touch n’ heat Calamus Duo Elements, Super Endo α 2) as well as injectable gutta-percha ( e.g. (3) This technique requires clinicians to use a heat carrier ( e.g. Nowadays, there are several techniques which originated from the classic Schilder’s technique. This is the most commonly used technique in North America. With respect to obturation, there are 3 techniques that are employed. Carefully clean and shape the canals in furcation areas to decrease furcation involvement.Manage the apical preparation of the canal to avoid transportation or unnecessary enlargement.Preserve tooth structure while reducing the risk of vertical root fracture in the future. ![]() Ensure there is a glide-path before using rotary files.Completely remove infected material from the canal space.This will optimize the files’ efficiency and minimize damage to the canal and tooth.Įach file system has advantages and disadvantages the best system is the one you are proficient with and used to handling.Īdditionally, clinicians must adhere to the principles of endodontic treatment: The most important factor when choosing and utilizing a particular file system is to follow the appropriate technique outlined by the manufacturer and dictated by the design of the file to remove vital or necrotic tissues from the canal spaces. Examples include: ProTaper, Twisted Files, Endosequence.Cut more effectively but can also lead to errors if not properly managed.Enable cleaning and shaping but the procedure is slower and safer.However, several research studies have illustrated that regardless of the type of file used to shape the canal, none are able to contact all the canal walls or surfaces. Rodrigo Cunha, Assistant Professor and Division Head, Endodontology Program Director in the faculty of Dentistry at the University of Manitoba provided this initial answer.Ĭurrently, there are several rotary endodontic systems in the dental market and all designed with one specific goal in mind – to clean and shape the canal(s). This question was submitted by a general dentist: Which rotary endodontic and obturation system is the best?ĭr.
