Abstract

Aim: The objectives of this study were to compare the clinical outcomes of root canal treatment between calcium silicate-based sealer using the cold hydraulic condensation technique and epoxy resin-based sealer using warm vertical compaction and to identify the prognostic factors affecting the outcomes of both obturation techniques. Methodology: Dental records and radiographs of the teeth that received root canal treatment with calcium silicate-based sealer using the cold hydraulic condensation technique or epoxy resin-based sealer using warm vertical compaction during 2015–2021 were selected using inclusion and exclusion criteria. The cases were matched between the two groups based on four factors: primary root canal treatment or retreatment, tooth type, periapical lesion and its size and extension of root canal filling. The success rates of root canal treatment between two sealers/obturation techniques were analysed. The incidence and resorption of extruded sealer were evaluated using the McNemar's test. Generalized estimated equations were used to evaluate any prognostic factors. Results: The median recall period of this study was 15 months. A total of 234 teeth, comprising 117 cases in each sealer/obturation group, were included. No significant difference was found in the success rates between the calcium silicate-based sealer using the cold hydraulic condensation technique group (91.5%) and the epoxy resin-based sealer using the warm vertical compaction group (94.9%). The incidence of sealer extrusion for the calcium silicate-based sealer (27.6%) did not significantly differ from that of the epoxy resin-based sealer (36.2%), with both sealers typically demonstrating no resorption at recalls. No prognostic factors related to the success rate of either technique were detected. Conclusion: The study findings suggest no difference in the success rate between calcium silicate-based sealer and epoxy resin-based sealer. The study did not identify any prognostic factors that significantly influenced the outcomes of the endodontic treatments.
