Antibacterial activity of resin adhesives, glass ionomer and resin-modified glass ionomer cements and a compomer in contact with dentin caries samples

A total of 103 clinical samples of carious dentin were used to study the an tibacterial action of different dental resin adhesive materials (Gluma 2000 , Syntac, Prisma Universal Bond 3, Scotchbond Multi-Purpose and Prime&Bond 2.0) glass ionomer cements (Ketac-Cem, Ketac-Bond, Ketac-Silver, Ketac-Fil) resin-modified glass ionomer cements (Fuji II LC, Vitremer and Vitrebond) and a compomer (Dyract), The agar plate diffusion method was used for the m icrobial cultures and a chlorhexidine control The growth of the caries-prod ucing microorganisms was effectively inhibited by the Vitremer and Vitrebon d cements, and to a lesser extent by the Scotchbond Multi-Purpose adhesive system. Overall, there were statistically significant differences in the an tibacterial activity of the products tested.
