In vitro evaluation of antibacterial effects of photo-cured glass ionomer liners and dentin bonding agents during setting.
Two dentin bonding agents (Optibond and Syntac), an enamel bonding agent (Heliobond), and two photo-cured glass ionomer cements (Vitremer and Variglass VLC) and their inhibitory effects on bacterial growth during setting were examined. Cultures of eight bacterial species were used to test these materials, except for Vitremer glass ionomer cement, which was tested against only five species. The photo-cured glass ionomer cements and the Syntac dentin bonding system with glutaraldehyde demonstrated a significant inhibitory effect on the growth of several bacteria. Meanwhile, Variglass VLC glass ionomer cement did not exhibit this effect on Lactobacillus casei and Streptococcus sobrinus. Optibond light-cured dentin bonding agent, with fluoride and fillers in its composition, and Heliobond (negative control group) did not demonstrate any inhibitory effect.
