Appel, D., Schäfer, E., Appel, C. - Success rate of orthograde endodontic retreatment after failed apicectomy – a retrospective study. International Endodontic Journal 2023; 56:7: 819–826
Results: The mean follow-up of the included 191 patients (124 females, 67 males) was 32.13 (±23.68) months and the median was 25 months. The overall recall rate was 54%. Cohen Kappa analysis revealed nearly perfect agreement between both observers (k = 0.81; p = 1.0). The overall percentage of success was 84.82% (complete healing 79.06%, incomplete healing 5.76%). The median survival was 86 months (95% CI: 56–86). None of the selected predictors had an influence on the treatment outcome (p > .05).
Conclusions: Orthograde retreatment should be considered a valuable treatment option after failed apicectomy. A surgical endodontic retreatment can still be a treatment option after orthograde retreatment to obtain outcome for the patient.
