WANT to talk about a new feature on the Web where we are going to do a tremendous amount of writing. I have been puzzled for a long time about exactly what all our teachings constitute and how to sum them all up in one word. It dawned on me that what we are really trying to teach is rational endodontics, a common-sense way to perform challenging tasks that should not be made more challenging by systems that introduce greater insecurities. From my early experiences with rotary NiTi, I appreciated the greater tapered shaping done with an engine that reduced hand fatigue, but I was never comfortable with the increased incidence of separated instruments and all the precautions that had to be taken to reduce that frequency of incidence.

HY am I in pain?” is a question that practitioners hear often. Pain is the chief complaint that plagues many frustrated patients. A few patients have been in “pain” yet state, “My dentist doesn’t see anything!” Patients who are feeling pain without an obvious cause may emphasize the fact that they are sane or not crazy. These patients sometimes reinforce to me the feeling that no one believes them but that the pain is unbearable. Many times patients with continuous pain have seen physicians along with neurologists and psychologists only to be referred back to the dentist. The patient just feels pain and needs help.
ILE SEPARATION can be one of the most frustrating — and even fear-provoking — aspects of performing root canal therapy. If a file fragment prevents the practitioner from adequately debriding and sealing the canal space, the case will be more likely to fail, resulting in the loss of the tooth. File retrieval is possible when the file can be visualized through a microscope. However, the retrieval often necessitates an excessive removal of root dentin, rendering the tooth more prone to vertical root fracture. An alternative to retrieval of a separated file does exist. . . .
HOOSING an endodontic system from the many types being promoted out there can be confusing and expensive. Rotary NiTi has been the most popular system used and is heavily marketed in dental schools around the country. Every dentist graduating from school has had at least some knowledge or experience with Pro Tapers, Pro GT, or Profiles. The problem with rotary NiTi is the instruments’ susceptibility to separation in curved canals due to high torsional stress on the file at the curve. The cost of these files can add up when you start throwing them away after a couple of uses to prevent separation. Rotary NiTi has its limits in cases where the apical end of the root is bent at 90 degrees or more. The flexibility of the file will not allow you to pre-bend the file to get it into the curve. Because of its shortcomings and because the costs of the unit and files are so high, many general practitioners are always looking for an alternative system.
NE of the more difficult parts of the endodontic procedure is knowing how many canals there are and finding them. The morphology for each type of tooth is generally consistent for teeth in that category: molars, bicuspids, canines, laterals, and centrals. However. each category will have variations within its own group. These variations within each group will fall into several repeatable morphologies.
