“…Since calcium silicate‐based sealers require moisture for setting, they were evaluated by placing two pieces of wet cloth between the mould and the glass plates, as proposed by Tanomaru‐Filho et al . (). The specimens were then removed from their moulds and weighed on an analytical balance (Ohaus Adventurer, Model AR2140, São Bernardo do Campo, SP, Brazil).…”

“…The moulds were placed on a glass plate covered with cellophane film and filled; then, another glass plate also covered with cellophane film was placed on the moulds, after which the assembly was placed in an incubator at 37°C and relative humidity of 95%, for a period corresponding to three times that of their setting time. Since calcium silicate-based sealers require moisture for setting, they were evaluated by placing two pieces of wet cloth between the mould and the glass plates, as proposed by Tanomaru-Filho et al (2017).

“…Premixed, ready-to-use calcium silicatebased endodontic sealers, such as EndoSequence (Brasseler, Savannah, GA, USA) and TotalFill BC Sealer (FKG Dentaire, La Chaux-de-Fonds, Switzerland), have been studied (Zamparini et al 2019). TotalFill BC has adequate physicochemical properties, but appears to be soluble (Poggio et al 2017, Tanomaru-Filho et al 2017, Colombo et al 2018. Recently, the new calcium silicate-based Sealer Plus BC (MK Life, Porto Alegre, RS, Brazil) and Bio-C Sealer (Angelus, Londrina, PR, Brazil) were developed and introduced.…”

“…When solubility is evaluated volumetrically, based on digital image analysis by micro-computed tomography (micro-CT), solubility and dimensional changes can be evaluated by the same test (Silva et al 2017). Although TotalFill BC had high solubility when evaluated according to conventional tests, this material had volumetric stability in the micro-CT assessment (Tanomaru-Filho et al 2017).…”

Aim To assess the effect of immersion in distilled water or phosphate‐buffered saline (PBS) on the solubility, volumetric change and presence of voids of calcium silicate‐based root canal sealers (TotalFill BC, Sealer Plus BC and Bio‐C), in comparison with the gold standard epoxy resin‐based sealer (AH Plus). Methodology All properties were evaluated after immersion in distilled water or PBS. Solubility was determined by the percentage of mass loss, whereas volumetric change and presence of voids were evaluated by micro‐computed tomography, after 7 days of immersion. The volumetric change and percentage of voids between the baseline (after setting) and the experimental period were calculated. Statistical analysis was performed using one‐way anova and Tukey's or Student's t‐tests (α = 0.05). Results The calcium silicate‐based sealers had significantly greater solubility and volumetric loss than AH Plus, after immersion in distilled water or PBS (P < 0.05). Bio‐C had the greatest solubility (P < 0.05), followed by TotalFill BC and Sealer Plus BC, which were similar (P > 0.05). Regarding the volumetric change, AH Plus had a volume increase, with similar values in distilled water and PBS (P > 0.05). TotalFill BC, Sealer Plus BC and Bio‐C had a similar volumetric change (P > 0.05). The calcium silicate‐based materials had the greatest solubility and volume loss after immersion in distilled water (P < 0.05). There was no difference in the percentage of voids amongst the sealers, before and after immersion in distilled water or PBS (P > 0.05). Conclusions TotalFill BC, Sealer Plus BC and Bio‐C had significantly greater solubility and volumetric loss than AH Plus. Although storage in PBS significantly reduced the solubility and volumetric change of calcium silicate‐based sealers, their solubility remained above that recommend by ISO 6876. All the sealers evaluated had low and similar voids, even after immersion in distilled water or PBS.

Objectives To evaluate the biological and physicochemical features of bioactive root canal sealers. Materials and methods Human periodontal ligament fibroblasts (hPDLF) and human osteoblasts (hOB) were exposed to eluates of three bioactive root canal sealers, GuttaFlow® bioseal (GF), BioRoot™ RCS (BR), and TotalFill® BC Sealer (TF), and the epoxy resin–based sealer AH plus® (AH). Cytotoxicity and cellular inflammatory response were evaluated. The osteogenic potential was examined using human mesenchymal stem cells (hMSC). Film thickness, flowability, and pH were assessed. Root canal treatment was performed on human extracted teeth to evaluate the sealers’ tightness towards bacterial penetration. The antibacterial activity against common pathogens in primary root canal infections was tested. Results AH was severely cytotoxic to hPDLF and hOB (p < 0.001). The bioactive sealers were generally less cytotoxic. IL-6 levels in hPDLF were elevated in the presence of AH (p < 0.05). AH and GF suppressed IL-6 production in hOB (p < 0.05). AH and BR stimulated the PGE2 production in hPDLF and hOB (p < 0.05). BR was the only sealer that led to calcium deposits in hMSC (p < 0.05). TF and AH showed the lowest film thickness and the highest flowability. Bacterial tightness was best in teeth filled with AH and BR. All sealers showed similar antimicrobial activity, but the overall antimicrobial efficacy was moderate as the bacteria were reduced by just one log scale (p < 0.05). Conclusions This study revealed favorable in vitro results regarding the biocompatibility of the bioactive root canal sealers. Clinical relevance Bioactive root canal sealers may be a useful alternative to epoxy resin–based sealers.

Abstract: TFBC presented the highest pH and solubility, but showed similar VC to GFB and AH Plus. GFB showed proper physicochemical properties. Micro-computed tomography complements the physicochemical analysis of endodontic sealers.
