Antibacterial effect of an antibacterial adhesive system, and a resin modified glass ionomer liner

To evaluate the antibacterial effect of an antibacterial adhesive system and a resin modified glass ionomer liner against Streptococcus mutans. The antibacterial effect of the tested materials was evaluated using the agar disc diffusion test. Filter paper discs loaded with the tested materials were applied to agar plates previously inoculated with Streptococcus mutans. After incubation the inhibitory effect of the materials were evaluated by measuring the size of the inhibition zones. Resulted showed that both of the tested materials have a strong antibacterial effect. The primer of the anti bacterial adhesive system has significantly high antibacterial effect than the resin modified glass ionomer [Vitribond] [P < .001]. The use of the antibacterial adhesive system for bonding of composites provides higher antibacterial effect than the use of glass ionomer liner with composite resin restorations
