Impact of integrated quaternary ammonium compounds in conventional glass-ionomers on cariogenic oral microflora: An in vitro analysis

The incorporation of antimicrobial agents into conventional glass-ionomers demonstrated an inhibitory effect on all examined cariogenic bacteria. This effect was more significant at higher concentrations. Over time, the suppressive effect diminished; however, it remained significantly strong. Glass-ionomers lacking antimicrobial agents demonstrated a restricted but noticeable antibacterial efficacy.
