The outcome of root canal treatment with a calcium silicate-based sealer of necrotic teeth: a retrospective assessment

Aim: This retrospective clinical assessment aimed to evaluate the healing effect of calcium silicate- based root canal sealers on necrotic teeth with periapical lesions. Methodology: An assessment of the outcome was carried out based on the patient's clinical records and radiographic data. The study involved 20 teeth in total: 9 of which were posterior and 11 anterior. Obturation was performing using either a single cone or a lateral compaction technique. The differences in sizes of lesions were characterized as large, medium, and small lesion sizes. Initial, final, and follow up periapical radiographs were taken and scored with the aid of periapical index scoring system. Results: The mean follow-up period was 15.8 months. Interobserver agreement was evaluated by Kappa test and categorical variables were evaluated by Fisher's Exact test. The overall success rate was 100%, with 70% of patients being fully healed and 30% assessed as healing. Variables did not differ statistically significant. Conclusion: Calcium silicate-based sealers have good healing capacity even in the presence of significant periapical lesions.
