Abstract:

The object of the present study was to Functionalize adhesive system with antibacterial activity without interfering the bonding effect, to kill bacteria residue on cavity and prevent bacteria from colonization on the margins of bonding. The fluorine-containing imidazolium salt antibacterial monomer was synthesized by the combination reaction of 1-chlorododecane and 1-vinylimidazole, and the replacement reaction to introduce fluoride ion. The synthesized intermediate product and final product were characterized by nuclear magnetic resonance spectroscopy. Fluoride ion was introduced into the bonding system in the form of organic fluorine, and the release behavior of fluoride ion from the functionalized adhesive was studied. The antibacterial experiment showed that the functionalized adhesive was endowed with good antibacterial property, which realized targeted anti-caries ability. The bond strength test indicated that the functionalization with the fluorine-containing imidazolium salt monomer did not affect the bonding performance of the adhesive. These results suggested that adhesive functionalized with the fluorine-containing imidazolium salt monomer had potential for reducing the occurrence of clinical secondary caries.
