“…This is beside the presence of tricalcium silicate phase within the cement which was responsible for acquiring the material strength through the formation of calcium silicate hydrate gel after mixing [19] . As per Torabienjad -the father of MTA-, the compressive strength of MTA increases with time and this was in accordance with the current study, which is also in agreement with Ghaseni et al and Tanomaru-Filho et al and this may be due to white MTA consists of bismuth oxide and a radiopacifying particles which did not contribute into the hydration reaction of MTA, and therefore its presence may lead to the creation of flaws within the cement matrix which in turn reflect on the compressive strength of the cement leading its measurement reduction [20] [21] . As for the Thera-Cal results in this paper, it might be attributed to the radiopaque material combined in the cement could be ytterbium fluoride, barium sulfate or bismuth oxidem [22] .…”

“…In this study, the highest radiopacity was recorded for both Angelus White Mineral Trioxide Aggregate group (9.38 ± 0.63) and TheraCal group (9.43 ± 0.60). For the MTA, it has bismuth oxide in its constituent which is considered as radiopacifying material giving a good radiopacity and this was in agreement with Tanomaru-Filho et al [21] . Additionally, the theracal has radiopacifying agent incorporated in the cement and could be ytterbium fluoride, barium sulfate or bismuth oxide as stated by Xuereb et al and the high atomic number of such materials led to their good radiopacity.…”

This in-vitro study evaluated the compressive strength and radiopacity of denovo synthesized calcium silicate cement containing zinc oxide nanoparticles versus commercial materials. A total of 100 specimens were prepared for this study, 25 of them were prepared for each of the 4 materials group: Synthesized Calcium Silicate Cement (SYNT), Nano Zinc Oxide added to the synthesized calcium silicate cement (NANO), Angelus White Mineral Trioxide Aggregate (MTA) and Theracal (THCL). The 25 specimens of each group was then distributed as follows: 10 were tested for compressive strength (MPa) on day 10, 10 were tested for compressive strength (MPa) on day 30; the last 5 specimens were tested for radiopacity. Data was then recorded, tabulated and statistically analyzed. The mean MPa results on day 10 recorded the highest by THCL-10 (55.35 ± 9.82), while the lowest value was recorded for NANO-10 (4.90 ± 1.61). The mean MPa on day 30 recorded by the NANO-30 (52.66 ± 19.30) was the highest, while the lowest value was recorded for SYNT-30 (21.70 ± 2.55). All subgroups on day 10 compared to those on day 30 showed significant statistical difference at p<0.05; Where the mean MPa of SYNT-30 was less than that of SYNT-10, the same was observed for the THCL subgroups. As for the mean MPa of NANO-30 was higher than that NANO-10, the MTA subgroups expressed the same results. On the other hand, the radiopacity results showed that the highest mean radiopacity value was recorded for THCL (9.43 ± 0.60), followed by MTA (9.38 ± 0.63), then NANO (5.06 ± 0.54), while the lowest value was recorded for SYNT (1.26 ± 0.24). In conclusion, the incorporation of zinc oxide nanoparticles in calcium silicate based enhances the physicomechanical properties of the cement expressed in terms of compressive strength and radiopacity in comparison to commercially available materials such as MTA and theracal.

“…Moreover, the tricalcium silicate bone cement manufactured by sol‐gel synthesis has a porous structure with high surface energy for chemical reaction, which might have enhanced the hydration reaction and be less affected by environmental interferences such as acidic conditions, when used to repair perforations 16,28 . These results are consistent with many previous studies 22,29–33 …”

This study compares the immunohistochemical reaction of a new experimental tricalcium silicate perforation repair material to mineral trioxide aggregate (MTA) and Biodentine. A total of 162 mature premolar teeth from 12 dogs were divided into three experimental groups (n = 54 teeth each) according to the evaluation period: 1, 2 and 3 months. Each group was further divided into two equal subgroups (n = 27 teeth each) according to the time of repair: immediate repair and delayed repair. Each subgroup was subdivided according to the material used into three experimental subdivisions (n = 8 teeth each): MTA, Biodentine (Septodont) and experimental material, and two control subdivisions: positive control (n = 2 teeth) and negative control (one tooth).

“…It is also noteworthy that in a dry and heated environment, BioRoot RCS had a significantly shorter setting time, possibly due to the enhancement of calcium chloride (setting time accelerator) with the increase in temperature, as previously reported (Xuereb et al . 2016).…”

Heating stability, physical and chemical analysis of calcium silicate‐based endodontic sealers

Aim To evaluate possible modifications in root canal sealers subjected to a variety of heating conditions using vibrational spectroscopy and analysis of physical and chemical properties. Methodology EndoSequence BC Sealer HiFlow, Bio‐C Sealer, BioRoot RCS and AH Plus were analysed chemically using Raman spectroscopy (25–220 °C) and Fourier‐transform infrared spectroscopy (FT‐IR) (37–100 °C ). For FT‐IR, the materials were tested individually and mixed with root dentine powder. Scanning electron microscopy (SEM) and coupled energy dispersive spectroscopy (EDS) were used to evaluate surface and chemical elements. ISO 6876‐2012 and ASTM‐C266‐07 specifications were followed to evaluate flow, setting time (moist and dry), solubility and radiopacity. Also, pH analysis at 37 and 100 °C was performed. Shapiro–Wilk and Mixed ANOVA (within and between the effects of the subjects), Levene, and a post hoc analyses with Bonferroni correction were performed (P < 0.05). Results Vibrational spectroscopy revealed peaks of tricalcium silicate, dicalcium silicate and zirconium dioxide. Chemical changes in the Raman spectra during heating were discrete, as the inorganic content predominated the signalling for all root canal sealers. FT‐IR analysis exhibited spectral changes in water absorption for EndoSequence BC Sealer HiFlow and Bio‐C Sealer, probably related to dehydration. For BioRoot RCS and AH Plus, no significant chemical changes were observed. Bio‐C Sealer exhibited a band of polyethylene glycol only after heating to 100 °C, probably related to its thermal decomposition. SEM/EDS analysis corroborated the composition results observed in vibrational spectroscopy for all materials. Heating to 100 °C significantly changed the flowability of all calcium silicate‐based sealers with a wide variation in setting times at both temperatures, along with solubility levels above ISO standards. For all tested sealers, radiopacity fulfilled the requirements, and pH exhibited alkaline values. Conclusions The tested calcium silicate‐based sealers were affected by heating. Calcium silicate‐based root canal sealers had high solubility which is a concern for their clinical use. AH Plus was the only root canal sealer that was stable after heating.
