Abstract

To ensure long-term success in endodontic treatment, completely sealing the root canal is crucial. To achieve this, the root canal must be filled with gutta-percha cones in combination with a root canal sealer. Therefore, the current study aims to evaluate the sealing capability of two types of calcium silicate sealers: self-mixed Bioroot^TM RCS and pre-mixed CeraSeal. Objective: To compare the level of microleakage at the apex region of teeth treated with two types of calcium silicate sealers at intervals of 2 days and 90 days using the dye penetration measurement technique. Subjects and methods: Forty four extracted mandibular premolars with fully formed apical roots and a single canal were collected for this study. Results: At the 2-day interval after endodontic treatment (TBOT), the average microleakage of the group treated with sealer Bioroot^TM RCS (0.98 mm) was lower than that of the group treated with sealer CeraSeal (1.25 mm). This difference was not statistically significant (p >0.05). At the 90-day interval, the average microleakage for the group treated with sealer Bioroot^TM RCS (0.67 mm) remained lower than that of the group treated with sealer CeraSeal (0.92 mm). This difference also was not statistically significant (p >0.05). Conclusion: From the two intervals surveyed, we found that the sealing efficacy of sealer CeraSeal is comparable to that of sealer Bioroot^TM RCS.
