“…The rate of dicalcium silicate hydration is slower than that of tricalcium silicate in the composition of calcium silicate cements. Therefore, later dicalcium silicate hydration may improve the cement strength in the presence of humidity 31) . This can consequently lead to more CSH formation and higher strength acquisition.…”

Novel fast-setting calcium silicate cement with fluoride (CSC) has been developed for potential applications in tooth crown. The aim of this study was to test the diametral tensile strength (DTS) of different CSC compositions in humid condition on day1, 28, and 180. We tested 'bond CSC' with 3.5% fluoride and no radiocontrast, 'CSC' with 3.5% fluoride and 10% radiocontrast, 'ultrafast CSC' with 3.5% fluoride and 20% radiocontrast, 'high fluoride CSC' with 15% fluoride and 25% radiocontrast, Biodentine, and MTA. We filled the cements after mixing to cylindrical molds. Specimens were stored in >95% humidity. DTS was measured at each time point. CSC compositions had statistically higher DTS compared to MTA and Biodentine on day1. Bond CSC showed higher DTS versus all cements, except CSC, at all time points. DTS of all cements, except Biodentine, significantly increased in humid condition on day28 and day180 compared to day1.

“…However, various in vivo studies that assessed the biocompatibility of this cement (21,22) demonstrated that after 30 days, the material allowed adequate tissue repair, indicating that the alkaline pH produced by calcium ion release was maintained (22,23). It is believed that this ability to maintain the alkaline pH of the medium is the main responsible for the excellent biological performances of MTA and EndoBinder (21).…”

Cytotoxicity of New Calcium Aluminate Cement (EndoBinder) Containing Different Radiopacifiers

et al. 2017

This study aimed to evaluate the cytotoxicity of a calcium aluminate cement (EndoBinder) containing different radiopacifiers, Bi 2 O 3 , ZnO or ZrO 2 , compared with Mineral Trioxide Aggregate (MTA). According to ISO 10993-12:2012 (E) recommendations, 0.2 g of each cement were applied in transwell inserts and placed in 24-well culture plates containing 1 mL of culture medium (DMEM). After 24 h of incubation, the extracts (DMEM containing components released from the cements) were applied to immortalized odontoblast-like MDPC-23 cells. Cell viability (MTT test), alkaline phosphatase activity (ALP), total protein production and cell morphology (Scanning Electron Microscopy -SEM) were evaluated. The volume of 50 µL of extract was used to determine the chemical elements released by the cements using Energy Dispersive Spectroscopy (EDS). The following groups were established (n=6): NC -negative control (without treatment); EB -EndoBinder without radiopacifier; EBBO -EndoBinder+Bi 2 O 3 ; EBZnO -EndoBinder+ZnO; EBZrOEndoBinder+ZrO 2 and WMTA -White MTA. Data were subjected to statistical analysis (Kruskal-Wallis test, level of significance=5%). Cells exposed to the different versions of EndoBinder presented small reduction in viability, total protein production and ALP activity, with values similar to the NC and WMTA groups (p>0.05). Different elements (C, O, Na, Al, P, Si, Cl, Bi, K) released by the cements were detected in the extracts. However, the cells had no significant changes in their morphology. EndoBinder and MTA did not affect negatively the metabolism of the odontoblastic-like cells, showing it to be cytocompatible, irrespective of the used radiopacifier.

“…Therefore, a number of studies have suggested the use of PC as a less expensive alternate of MTA in dental practices 12,17,18) . However, in contrast, several researchers disagree with the idea of using PC in dental applications and have reported differences between MTA and PC in terms of chemical composition, surface chemical characteristics, compressive strength, cation release and particle sizes 2,15,[19][20][21] . As the potential of PC in providing an inexpensive solution to economic drawbacks of MTA is eclipsed by the controversy existing between the reported studies, there is a need to further probe in to the characterization and comparison of MTA and PC.…”

Chemical and morphological characteristics of mineral trioxide aggregate and Portland cements

et al. 2016

View full text Add to dashboard Cite

The purpose of this study was to investigate the chemical composition and particle morphology of white mineral trioxide aggregate (WMTA) and two white Portland cements (CEM 1 and CEM 2). Compositional analysis was performed by energy dispersive X-ray spectroscopy, X-ray fluorescence spectrometry and X-ray diffraction whereas, morphological characteristics were analyzed by scanning electron microscope and Laser scattering particle size distribution analyzer. The elemental composition of WMTA, CEM 1 and CEM 2 were similar except for the presence of higher amounts of bismuth in WMTA. Calcium oxide and silicon oxide constitute the major portion of the three materials whereas, tricalcium silicate was detected as the major mineral phase. The particle size distribution and morphology of WMTA was finer compared to CEM 1 and CEM 2. The three tested materials had relatively similar chemical composition and irregular particle morphologies.
