“…The set sealer produced has been found to be biocompatible and bioactive [2,3]. Hydroxyapatite, as a secondary byproduct, is deposited on the surface of the set sealer, contributing to the bioactivity of the set CSS [3]. The emanation of calcium hydroxide ions from CSSs elevates the pH, which contributes to the sealers' antimicrobial efficacy [2,4].…”

This review explores the field of retreatment strategies for cases filled with calcium silicate-based root canal sealers. Since the introduction of calcium silicate-based materials in dentistry, calcium silicate-based root canal sealers have become popular among dentists because of their biocompatibility, bioactivity, and sealing ability. Therefore, effective retreatment strategies are indispensable. This article aims to identify the challenges associated with the removal of calcium silicate-based sealers themselves and removal of gutta-percha with the sealers during retreatment, evaluate current techniques and materials, and provide future directions for research in this field. Regarding the strategies of removal of root canal sealers, calcium silicate-based sealers are still relatively new materials for clinicians compared with traditional sealers such as epoxy- or eugenol-based sealers. First, no clinically established solvents have been reported. Second, calcium silicate-based sealers are currently utilized by clinicians in either the cold sealer-based technique or the warm vertical condensation technique. Third, the setting process of calcium silicate-based sealers generates byproducts, primarily calcium hydroxide and secondarily hydroxyapatite, that could interact with dentine. Lastly, there is a lack of clinical studies evaluating the efficacy of retreatment protocols for teeth filled with calcium silicate-based sealers. Therefore, it is important to investigate the chemo-mechanical properties of calcium silicate-based sealers themselves and their reactions to solvents and/or mechanical instruments and identify the interfacial properties of calcium silicate-based sealers with respect to dentine and gutta-percha. In addition, researchers in the clinical field need to actively gather and report data on retreatments of teeth filled with calcium silicate-based sealers.

“…In recent years, calcium silicate-based sealers, also called bioceramic sealers, have attracted attention [ 13 ]. They are alkaline and release calcium ions to form an apatite layer [ 10 14 ]. Thus, their bioactivity and biocompatibility can be said to be important features compared to conventional sealers [ 15 ].…”

Objectives This study investigated the nanoleakage of root canal obturations using calcium silicate-based sealer according to different drying methods. Materials and Methods Fifty-two extracted mandibular premolars with a single root canal and straight root were selected for this study. After canal preparation with a nickel-titanium rotary file system, the specimens were randomly divided into 4 groups according to canal drying methods (1: complete drying, 2: blot drying/distilled water, 3: blot drying/NaOCl, 4: aspiration only). The root canals were obturated using a single-cone filling technique with a calcium silicate–based sealer. Nanoleakage was evaluated using a nanoflow device after 24 hours, 1 week, and 1 month. Data were collected twice per second at the nanoscale and measured in nanoliters per second. Data were statistically analyzed using the Kruskal-Wallis and Mann–Whitney U -tests ( p < 0.05). Results The mean flow rate measured after 24 hours showed the highest value among the time periods in all groups. However, the difference in the flow rate between 1 week and 1 month was not significant. The mean flow rate of the complete drying group was the highest at all time points. After 1 month, the mean flow rate in the blot drying group and the aspiration group was not significantly different. Conclusions Within the limitations of this study, the canal drying method had a significant effect on leakage and sealing ability in root canal obturations using a calcium silicate-based sealer. Thus, a proper drying procedure is critical in endodontic treatment.

“…Although epoxy resin-based root canal sealers have a low rate of solubility [8] and a high possibility of dentin adhesion [9], they have a degree of toxicity with no bioactive properties [10]. Calcium silicate-based materials are widely used owing to their biological and bioactive behaviors [11,12].…”

“…It was proven that all calcium silicate-based root canal sealers, including bioceramic sealers, possess a high solubility percentage that exceeds the acceptable limit [6,8,16,17] that could be reduced by their bioactivity [11]. Bioceramic materials are characterized by their bioactive property, which is defined as the bio-mineralization ability of the material to induce the formation of hydroxyapatite-like crystals on their surface when exposed to tissue fluid.…”

Since the crystallinity of hydroxyapatite created by bioactive sealers could affect their solubility percentage, this study aimed to analyze the degree of crystallinity and mineral maturity of hydroxyapatite crystals formed by bioactive (Cerafil and Endosequence) root canal sealers. Set discs of each sealer were submerged, either in deionized water or phosphate buffer solution (PBS). After 30 days, the crystallinity indices, crystal size, and mineral maturity were determined. The data were statistically analyzed using ANOVA and Student’s t tests with significance set at p < 0.05. After immersion in PBS, Endosequence had the most significant value of mineral maturity (1030/1110Raman) and PO4/amide IFTIR ratio. However, the CO3/PO4 ratio was reduced by both solutions, particularly by PBS. There was no significant difference between both bioactive sealers. Compared to Endosequence, Cerafil had the highest crystallinity indices for CIXRD, CIFTIR, and CIRaman. AH-26 had a significantly greater crystal size (p < 0.001). There was no significant difference in the crystal size of the Cerafil and Endosequence bioactive sealers (p > 0.05). Overall, Cerafil and Endosequence successfully formed hydroxyapatite crystals when exposed to PBS, with high CIs obtained by Cerafil. The crystallinity and mineral maturity of Cerafil and Endosequence were comparable. On the other hand, AH-26 failed to produce hydroxyapatite.
