Bioactive glass (BG) composites with a base of SiO 2 –Na 2 O–CaO–P 2 O 5 are biocompatible biomaterials. The assessment of their abilities for medical applications has interested researchers. We produced a BG‐containing SiO 2 –MgO–CaO–P 2 O 5 by the sol–gel 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. © 2012 Wiley Periodicals, Inc. J Biomed Mater Res Part A, 2013.
