Hemolytic activity of five different calcium silicates.
Mineral characteristics and the in vitro hemolytic activity of three synthetic and two natural calcium silicates (CaSi) are compared. Hemolysis is higher for the synthetic compounds than for the natural ones. The difference is accentuated by weak ultrasonication of the minerals. No variation was observed within the two groups, including both acicular and fibrous forms. Calcium was released from...
متن کاملPart III MICROSTRUCTURE
This study was conducted to evaluate the effects of inclusion of fly ash on concrete microstructure and its mechanical performance. Air entrained plain portland cement concrete was proportioned to obtain design strength of 6000 psi at the 28-day age. Concrete mixtures were also proportioned to have various cement replacements in the range of 15 70% with an ASTM Class C fly ash. Microstructure o...
متن کاملEnhanced bioactivity of glass ionomer cement by incorporating calcium silicates
Glass ionomer cements (GIC) are known as a non-bioactive dental cement. During setting the GIC have an acidic pH, driven by the acrylic acid component. It is a challenge to make GIC alkaline without disturbing its mechanical properties. One strategy was to add slowly reacting systems with an alkaline pH. The aim of the present study is to investigate the possibility of forming a bioactive denta...
متن کاملBiological Effect of Calcium Phosphate Bioceramics Microstructure
Understanding of interactions between cells and biomaterials is a huge parameter for improving tissue engineering and regenerative medical fields. Many different materials have already been tested (including calcium phosphate ceramics) and it has been established that surface characteristic is a parameter that influences cell responses. The aim of this work was to characterize calcium phosphate...
متن کاملCalcium revisited: part I.
In February 2013, the US Preventive Services Task Force (see www.uspreventiveservicestaskforce.org) recommended 'against daily supplementation with 400 IU or less of vitamin D3 and 1000, mg or less of calcium for the primary prevention of fractures in non institutionalized postmenopausal women', which illustrates the divergence of opinions. This review wants to shed an objective light on the im...
