Endodontic retreatment versus dental implants of teeth with an uncertain endodontic prognosis: 3-year results from a randomised controlled trial.

CONCLUSIONS:The present preliminary results suggest that both endodontic retreatment and replacement of previously endodontically treated teeth with persisting pathology and a dubious endodontic prognosis provided similar short-term success rates. Aesthetics of the soft tissues and time needed to complete treatment were in favour of endodontic retreatment whereas implant rehabilitation required half of the chair time than endodontic retreatment, but was significantly more expensive. Much larger patient populations and longer follow-ups are needed to fully answer this question; however, in this scenario the less invasive endodontic retreatment could be the first therapeutic option to be considered.
