A new four-component bioactive glass containing Ag{sub 2}O was produced via the sol-gel process. This system releases Ag{sup +} which is a powerful antibacterial agent. The work reported herein is a comparative study of the bioactivity levels of conventional bioactive glass and of the new antibacterial glass. On the basis of XRD patterns, FTIR spectra, and ICP data, the bioactive behaviour of the two biomaterials is nearly equivalent. (orig.)
