| Outline of Final Research Achievements |
In this study, the experimental self-adhesive resin cements containing chlorhexidine diacetate (CHX) at various concentrations were prepared, and their antibacterial effects, bonding ability, and physical properties were evaluated. The experimental cements prepared by incorporation of CHX at 5 (wt)% or greater into a commercial dual-cure G-CEM LinkAce (GC Corp., Tokyo) exhibited antibacterial effects at uncured stage and inhibited biofilm formation on their surfaces after curing. In addition, the experimental cement containing 5 (wt)% CHX demonstrated dentin bonding ability and flexural strength acceptable for clinical use.
Thus, incorporation of CHX at 5 (wt)% into G-CEM LinkAce was found to be a promising approach to provide the self-adhesive resin cements with antibacterial activities.
