A long-term retrospective analysis of single tooth implants and endodontic therapies in a university setting.

Background: This study aimed to compare survival of single tooth implants (SI) to teeth receiving initial endodontic treatment (IET), non-surgical (NET), and surgical endodontic retreatments (SET). The secondary aim was to determine success rate and identify factors associated with the survival and success of implant and endodontic treatments.

Methods: A retrospective cohort study using electronic health records (January 1st, 1995 to April 30th, 2017) was conducted.
