Abstract
Objective: To observe any systematic difference between surgical and non-surgical endodontic retreatment of endodontic failures.
Design: Randomised controlled trial.
Intervention Ninety-five teeth in 92 patients were randomised to receive either surgical or non-surgical endodontic retreatment and followed up at 6, 12, 24 and 48 months.
Outcome measures: The proportion that healed (criteria not presented).
Results: At 12 months a statistically significant higher healing rate was found in the surgical group. This was not present at 48 months. From the data presented the proportion of teeth not requiring further retreatment during the 48 months were ascertained and a number needed to treat calculated (see Table 1).
Conclusion: There is no difference in the outcome of surgical and non-surgical retreatment at 4 years.
