MR Micro-imaging Study of Water Migration into Glass Ionomer Dental Cements - the Efficiency of Surface Coating
Introduction Glass Ionomer Cements (GIC) are widely used dental materials. They adhere to hard dental tissues, release fluoride ions and are bio-compatible [ 11. GIC are obtained from the reaction during the hardening process between a polymeric acid and acid-degradable glass. Water plays a crucial role in this reaction; its absence retards or prevents the reaction while high concentrations res...

متن کاملMicrostructural Changes Induced by CO2 Exposure in Alkali-Activated Slag/Metakaolin Pastes
The structural changes induced by accelerated carbonation in alkali-activated slag/ metakaolin (MK) cements were determined. The specimens were carbonated for 540 h in an environmental chamber with a CO2 concentration of 1.0 ± 0.2%, a temperature of 20 ± 2°C, and relative humidity of 65 ± 5%. Accelerated carbonation led to decalcification of the main binding phase of these cements, which is an ...
متن کاملThe Biocompatibility of Porous vs Non-Porous Bone Cements: A New Methodological Approach
Composite cements have been shown to be biocompatible, bioactive, with good mechanical properties and capability to bind to the bone. Despite these interesting characteristic, in vivo studies on animal models are still incomplete and ultrastructural data are lacking. The acquisition of new ultrastructural data is hampered by uncertainties in the methods of preparation of histological samples du...
متن کاملNovel Osteointegrative Sr-Substituted Apatitic Cements Enriched with Alginate
The present work describes the synthesis of novel injectable, self-setting bone cements made of strontium-substituted hydroxyapatite (Sr-HA), obtained by single-phase calcium phosphate precursors doped with different amounts of strontium and enriched with alginate. The addition of alginate improved the injectability, cohesion, and compression strength of the cements, without affecting the harde...
