“…The sealers investigated in this study, AH Plus and PCS, are commonly used with warm vertical filling techniques (Aqrabawi , Hale et al ). Lately, calcium silicate‐based sealers designed for use in warm vertical filling techniques have been introduced (Donnermeyer et al ). As they were not available from commercial sources at the point this study was carried out, an investigation of physical and chemical properties should be matter of future research.…”

“…Root canal sealers based on calcium silicates were developed as materials that offer biocompatibility, bioactivity and nongenotoxicity (Donnermeyer et al . ). Premixed, ready‐to‐use calcium silicate‐based 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 .…”

“…Immersion of calcium silicate‐based sealers in phosphate‐buffered saline (PBS) led to surface precipitation of calcium hydroxyapatite in vitro , evidencing the bioactivity of these sealers (Donnermeyer et al . ). Nevertheless, information is still sparse, and further investigations are needed to evaluate the clinical relevance of bioactivity and solubility properties (Donnermeyer et al .…”

Effect of immersion in distilled water or phosphate‐buffered saline on the solubility, volumetric change and presence of voids within new calcium silicate‐based root canal sealers

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.

“…Hydraulic calcium silicate restoratives based upon Portland cement and its constituent dicalcium and tricalcium silicate phases are popular options for many endodontic procedures involving hard tissue repair and pulpal regeneration [1,2]. The properties and clinical applications of the current range of endodontic calcium silicate cements are extensively reported and reviewed in the recent scientific literature [1][2][3][4][5][6][7].…”

Impact of Bi2O3 and ZrO2 Radiopacifiers on the Early Hydration and C–S–H Gel Structure of White Portland Cement

Bismuth oxide (monoclinic α-Bi2O3) and zirconium oxide (monoclinic ZrO2) are the most popular radiopacifiers in commercial Portland cement-based endodontic restoratives, yet their effects on the setting and hydration reactions are not fully understood. This study compares the impact of 20 wt.% of Bi2O3 or ZrO2 on the early hydration reactions and C–S–H gel structure of white Portland cement (WPC). Cement paste samples were hydrated at 37.5 °C prior to analysis by 29Si and 27Al magic angle spinning nuclear magnetic resonance spectroscopy at 3 h and 24 h, and transmission electron microscopy at 3 h. Initial and final setting times were determined using a Vicat apparatus and reaction kinetics were monitored by isothermal conduction calorimetry. Bi2O3 was found to prolong initial and final setting times and retard the degree of hydration by 32% at 24 h. Heat evolution during the acceleration and deceleration phases of the hydration process was reduced and the exotherm arising from renewed ettringite formation was delayed and diminished in the presence of Bi2O3. Conversely, ZrO2 had no significant impact on either setting time; although, it accelerated hydration by 23% within 24 h. Increases in the mean silicate chain length and the extent of aluminum substitution in the C–S–H gel were observed in the presence of both radiopacifying agents after 24 h relative to those of the unblended WPC. The Bi2O3 and ZrO2 particles remained intact within the cement matrix and neither bismuth nor zirconium was chemically incorporated in the hydration products.
