In Vitro Bioactivity and Cytotoxicity of Chemically Treated Glass Fibers
Samples of a commercial glass fiber FM® (Fiber Max) were used to test the efficacy of a chemical sol-gel surface treatment to enhance their bioactivity. After treatment with tetraethoxysilane (TEOS), individual fiber samples were soaked into a simulated body fluid (SBF) solution, from which they were removed at intervals of 5 and 10 days. Micrographs obtained by scanning electron microscopy (SE...
متن کاملIn vitro bioactivity of S520 glass fibers and initial assessment of osteoblast attachment.
Bioactive glass fibers are attractive materials for use as tissue-engineering scaffolds and as the reinforcing phase for resorbable bioactive composites. The bioactivity of S520 glass fibers (52.0 mol % SiO(2), 20.9 Na(2)O, 7.1 K(2)O, 18.0 CaO, and 2.0 P(2)O(5)) was evaluated in two media, simulated body fluid (SBF) and Dulbecco's modified Eagle's medium (DMEM), for up to 20 days at 37 degrees ...
متن کاملThe In Vitro Bioactivity, Degradation, and Cytotoxicity of Polymer-Derived Wollastonite-Diopside Glass-Ceramics
Ca-Mg silicates are receiving a growing interest in the field of bioceramics. In a previous study, wollastonite-diopside (WD) glass-ceramics were successfully prepared by a new processing route, consisting of the heat treatment of a silicone resin embedding reactive oxide particles and a Ca/Mg-rich glass. The in vitro degradation, bioactivity, and cell response of these new WD glass-ceramics, f...
متن کاملIn vitro evaluation of acute cytotoxicity of human chemically treated allografts.
In order to minimize the risk of contamination associated with tissue transplantation, tissue banks commonly chemically treat the tissues whenever possible. As viral inactivation uses agents lethal to microorganisms, it is imperative to assure that chemically inactivated tissue remains biocompatible. In vitro assays can be an effective means to assess the acute cytotoxicity of chemically treate...
متن کاملIn vitro cytotoxicity of resin- reinforced glass ionomer cements
Previous studies indicated that toxic components can be released from glass ionomer cements and diffuse through dentinal tubules into the pulp. This in vitro study compared the cytotoxic effects produced to pulpal fibroblasts by the leachables of the primer systems and the diffusates through dentin of four resin-reinforced glass ionomer cements (Vitremer Tri Cure System, Dyract-Prime & Bond 2.0...
