Introduction Currently, no study has compared the outcome of nonsurgical root canal treatment (NSRCT) and single‐tooth implants (STIs) provided to the same patient. The purpose of this study was to determine if the survival outcome of the 2 treatment modalities is different. Methods The medical/dental records of 3671 patients with at least 1 STI and 1 NSRCT were reviewed. One hundred seventy patients with at least a 5‐year follow‐up were included. The survival outcome of NSRCT and STI and related factors were evaluated. Results Both treatments had a 95% survival rate with a mean 7.5‐year follow‐up. Most preoperative and postoperative factors involved in both procedures had no significant effect on the treatment outcomes. The number of adjunct and additional treatments, the number of appointments, the elapsed time before the final restoration, the number of prescribed medications, and the cost of the treatment were significantly higher for STI in comparison with NSRCT. Conclusions Both NSRCT and STI are highly successful treatments. Compromised teeth that could otherwise be saved by NSRCTs and deemed restorable should not routinely be treatment planned for STI.
