OR29 - Assessment of Differences in Clinical and Radiographic Outcomes of Endodontic Surgeries at Twelve Months Period Comparing Two Techniques: Endosequence BC putty and ‘Lid Technique’:- Endosequence BC Putty and Endosequence BC Sealer

Introduction: Currently, there are no published clinical studies on the success rates of endodontic microsurgeries when ES-BCRR is used as a retrograde filling material alone and using ES-BCRR and BC Sealer, aka lid technique. Therefore, the purpose of this retrospective study was to determine the clinical and radiographic outcomes of root end filling materials using both techniques. The null hypothesis was that there were no significant differences in the outcome of the EMS for two techniques.

Methods: Clinical records and periapical radiographs were collected from patients who had undergone endodontic microsurgery between 2008 and 2021 at UIC and had a minimum 1-year follow-up. All surgical procedures were performed by second year residents. Outcome was categorized into healed, healing, and non-healing on the basis of clinical and radiographic findings. The healed and healing cases were pooled and considered as success, and non-healing cases were considered failure.

Results: 50 patients met the inclusion criteria and were included in the study. Wilcoxon Signed Rank test was used to assess the healing between the 12-18 months and 6 months which shows statistically significant improvement from 6 months to 12-18months(p=.034).

Conclusions: In conclusion, this study shows high success rate with both BC putty and BC putty and BC sealer at 12-month period with no significant difference between the two techniques.
