title: Endodontic update 2006.
abstract: The past 10 years have witnessed more significant changes in the art and science of endodontics than the previous 100 years. This observation is no surprise, given that change is our only constant. The rate of change, however, has been anything but constant. The rate has accelerated so fast that all clinicians in the field of dentistry need a reliable source to guide us in what works. What works today in endodontics is the theme of this update. The discoveries and advancements in endodontic technology, instruments, and materials enable practitioners to achieve treatment outcomes that were previously considered unattainable. For example, in nonsurgical endodontic treatment, nickel titanium technology consistently can produce predictable radicular preparations that can be easily obturated. In nonsurgical re-treatment, the previous endodontic obturation attempt frequently can be removed and successfully re-treated largely because of enhanced vision and coaxial lighting from the operating microscope. Importantly, careful nonsurgical re-treatment usually can be accomplished without disruption to the existing restorations and without risk to ferrule integrity. In endodontic surgery underfilled foramina, and the isthmi between them, predictably can be connected and obturated with state-of-the-art miniature instruments. CLINICAL SIGNIFICANCE This article reviews the clinical endodontic breakthroughs encountered during the last decade and focuses on three primary topics: (1) finding canals; (2) following canals; and (3) finishing canals. Every day, dentists are faced with the interdisciplinary treatment planning question of to "save or not to save a tooth?" Dentists must routinely make the decision of whether to remove or restore the tooth based on biology, structure, function, esthetics, and value.(1) Occasionally, the endodontically treated tooth can be the weakest link in the restorative and esthetic sequence. This article examines the current state of endodontic technology, as well as the fundamentals of endodontic mechanics needed to achieve the most predictable endodontic outcome with the highest degree of success.
