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 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 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...
متن کاملFunctional and Performance Characteristics of Soluble Silicates in Deinking. Part I: Alkaline Deinking of Newsprint/Magazine
The function(s) of soluble silicates in repulpinghashing and flotation deinking of waste newsprint/magazine were investigated extensively, under optimized conditions. During repulping/washing, silicate ’s response was characteristic of a buffer and a detergent. It was responsible for a 3.0% increase in I S 0 brightness. In repulping/flotation, silicate accounted for a 6.1% increase in I S 0 bri...
متن کاملUnintended consequences: Why carbonation can dominate in microscale hydration of calcium silicates
The initial microscale mechanisms and materials interfacial process responsible for hydration of calcium silicates are poorly understood even in model systems. The lack of a measured microscale chemical signature has confounded understanding of growth mechanisms and kinetics for microreaction volumes. Here, we use Raman and optical spectroscopies to quantify hydration and environmental carbonat...
