The success rate of a restored, endodontically treated tooth is of interest to the dentist and patient when planning the treatment of a tooth requiring endodontics. The reported success rate for nonsurgical root canal treatment is varied within the dental literature. An alternative measure is tooth survival. This will include other factors related to endodontic treatment that result in poorer tooth survival. An understanding of the survival of endodontically treated teeth compared with alternative treatment modalities, such as dental implants, will provide for a more informed treatment plan.
