![]() ![]() However, by using rotary files that, by design, pull debris coronally rather than push it apically, we can further reduce the amount of extruded material.Įndodontists do not like to break files. What is the sequela of this? Increased postoperative sensitivity, if not frank pain and swelling. We are, in a sense, inoculating the periapical tissues. Quite often when performing a root canal with hand files, we push debris out past the end of the tooth. Additionally, a continuously tapered 0.06 preparation allows the use of an ultrasonic tip to generate acoustic streaming more effectively and achieve the cleanest possible canal.Īnother aspect of the 0.06 preparation that contributes to patient satisfaction is the reduction of extruded debris. A greater taper enhances the hydraulics of irrigation. Gates glidden burs make a parallel preparation in the coronal part of the canal. Canals that are preflared with gates glidden burs (and a 0.02 or 0.04 taper) are not as effectively irrigated as a 0.06 preparation. Your irrigation agent has the ability to work much more effectively in a tapered 0.06 preparation as compared to a 0.02 or 0.04 preparation. ![]() The only way to effectively clean these areas is with an irrigation agent. You should think of the root canal as a three-dimensional system with webs, fins, and anastomoses. 25/0.02 hand file to length? Not very effective! But with a 0.06 preparation, you are getting your irrigation agent into the root canal system right from the start. How effective is your irrigation agent when you can hardly screw a No. Additionally, the continuous 0.06 taper allows your irrigation agent (full-strength sodium hypochlorite) to work in a more efficient manner. Therefore, one benefit of this technique is more tactile awareness. Consequently, the removal of this tooth structure results in a dramatic increase in proprioceptive ability. When performing a continuously tapered 0.06 preparation, the larger taper removes that tooth structure in the coronal part of the canal that has a tendency to bind instruments. This combination leads to increased patient satisfaction, and will be a practice builder. Two of the major benefits of the 0.06 tapered preparation are a dramatic reduction in postoperative sensitivity for patients, and the ability to perform more cases in one visit. Why do endodontists prefer a continuously tapered 0.06 preparation? Actually, there are a number of reasons. If you can understand the rationale of a continuously tapered 0.06 preparation and perform it in a consistent manner, you will be stunned by how quickly endodontics can become predictable and a profit center in your practice. Here it is: a continuously tapered 0.06 preparation. ![]() If you are performing a lot of root canals, we want to let you in on a secret that endodontists know, but no one talks about. ![]()
