Oliveira IR, Pandolfelli VC, Jacobovitz M. Chemical, physical and mechanical properties of a novel calcium aluminate endodontic cement. International Endodontic Journal . Abstract Aim To evaluate the influence additives on several chemical cement based in comparison with mineral trioxide aggregate (MTA). Methodology Manipulation tests, measurements temperature, pH, ionic conductivity, compressive strength, apparent porosity, pore size distribution were carried out Gray‐MTA (Angelus)...
Graphene-related materials (GRM) show great potential as reinforcement in polymeric matrices, offering enhanced physicochemical and mechanical properties. In the aerospace sector, reinforced composites are increasingly used for their superior attributes design flexibility. Incorporating graphene nanoplatelets (GNP) into epoxy resin (ER) is a promising approach to enhance resin’s fracture toughness. The effectiveness of these nanocomposites depends heavily on dispersion nanoparticles within...
The present study evaluated the progression of osteogenic cell cultures exposed to a novel calcium aluminate cement (CAC+) in comparison with gold standard mineral trioxide aggregate (MTA). Cells were enzimatically isolated from newborn rat calvarial bone, plated on glass coverslips containing either CAC+ or control MTA samples center, and grown under conditions. Over 10-day culture period, roundening sample edges was clearly noticed only for group. Although both cements supported adhesion,...
Abstract Aim To evaluate mineral trioxide aggregate ( MTA ), Biodentine and several formulations of calcium aluminate cements CAC b) in terms their ability to release ions (Ca 2+ ) form apatite‐like precipitates after short‐term immersion phosphate‐buffered saline PBS its influence on the bond strength root‐end cavity. Methodology Ten samples , Biodentine, b calcium‐enriched cement b+) were placed contact with or deionized water for 14 days. The surfaces analysed using SEM EDS ‐X FTIR ....
Um dos aspectos principais para o desenvolvimento de concretos refratários está no aprimoramento conhecimentos sobre cimento alta alumina ou aluminato cálcio (CAC), já que esse ligante é mais utilizado nesta classe produtos. O objetivo desse trabalho foi analisar as informações disponíveis na literatura se obter um conhecimento aprofundado mecanismos ação aditivos retardadores e aceleradores da pega deste cimento. Da análise dados compilados pode-se concluir os agem geralmente duas maneiras:...
Numerous papers and publications report the use of microporous calcium hexaluminate (CaO.6Al2O3; CA6) as a key raw material for high temperature insulating materials. This has unique properties with respect to chemical purity mineral composition. Another important property CA6 is its structure, which consists platelet-shaped crystals that interlock. The free distance between defines structure. low density in combination micropores hampers heat transfer by radiation at temperatures exceeding...
Recent studies involving the use of calcium aluminate cement (CAC) as a biomaterial are based on commercial products. Improvements can be attained by investigating properties their crystalline phases in order to better design material's composition. Therefore, phase samples immersed simulated body fluid (SBF) solutions prepared according Kokubo's (KSBF) and Rigo's (RSBF) methodology had pH evaluated. The surfaces these were analyzed SEM, EDX XRD techniques. treatment with KSBF did not favor...
Abstract Aim To evaluate the effect of a calcium aluminate‐based cement ( CAC +) on development osteogenic phenotype in vitro . Methodology Rat calvaria‐derived cells were grown Thermanox ® coverslips for 24 h and then exposed to either samples (4‐h set) + or mineral trioxide aggregate MTA ) placed Transwell inserts periods up 14 days. Nonexposed cultures used as controls. The comparisons made using nonparametric Kruskal–Wallis test, followed by Student–Newman–Keuls post hoc test when...
