Overview

Background: This pilot prospective study analysed the clinical use of a new bioceramic premixed CaSi-containing sealer in association with a warm carrier-based technique. Methodology: Healthy patients (n = 38) requiring 40 root canal treatments were enrolled. Periapical X-rays were taken preoperatively, after root canal filling and after 1, 6, and 12 months. Two evaluators assessed the Periapical Index (PAI) and the sealer extrusion. The healing rate and survival rate were also evaluated. Barnard test was used to assess the relationship of each potential prognostic factor with periapical index (PAI) at 12-month follow-up. The significance level was set at 0.05. Results: Root canal treatments (n = 38) were analysed at the end-line (12 months). The total drop-out was 5% (two patients; two teeth). A total of 31 teeth (82%) (PAI 1-2) showed complete healing, while 7 (18%) are still healing. Cumulative survival was 100%. Apical extrusion of the sealers was observed in 18 cases (47%). Of these extrusions, nine (50%) resulted radiographically undetectable after 12 months. Conclusions: The study supports the use of premixed CaSi-based bioceramic sealers in association with carrier-based techniques. Periapical extrusion of the sealer and its radiographic modification or disappearance are possible events reported in the first 12 months.
