Procedural Errors in Endodontics

As can other complex disciplines of dentistry, root canal therapy can present unwanted or unforeseen challenges that can affect prognosis. These mishaps are collectively termed procedural accidents. However, fear of procedural accidents should not deter a practitioner from performing root canal treatment if proper case selection and competency issues are observed. Knowledge of the etiological factors involved in procedural accidents is essential for prevention. Also, methods of recognition and treatment and the effects of such accidents on the prognosis must be learned. Most problems can be avoided by adhering to the basic principles of diagnosis, case selection, treatment planning, access preparation, cleaning and shaping, obturation, and post space preparation.
