Abstract

Bioactive glass (BG) composites with a base of SiO2Na2OCaOP2O5 are biocompatible biomaterials. The assessment of their abilities for medical applications has interested researchers. We produced a BG-containing SiO2MgOCaOP2O5 by the solgel method. To determine the antibacterial effects, we analyzed the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) properties of this product on three microorganisms, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, known causative agents for biofilm formation on implant surfaces. In addition, we performed the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay to study the cytotoxic effects of our composite on animal cells. Our results demonstrated that our BG product inhibited the growth of bacteria in a concentration-dependent manner without any cytotoxic effects. Therefore, our BG product can be utilized as an appropriate implant for treating bone and tooth defects. (c) 2012 Wiley Periodicals, Inc. J Biomed Mater Res Part A, 2013.
