The purpose of this study was to determine the antibacterial activity of four dentine adhesive systems, Liner Bond II (Kuraray, LB), Scotchbond Multi-Purpose (3M, SC), Tokuso Light Bond (Tokuso, TO) and Imperva Bond (Shofu, IM) after curing. The cured specimens were made in the mould by applying each primer and adhesive, and placing composite with light irradiation. The bottom surface of the cured specimens was placed on agar plates which were inoculated with Streptococcus mutans, Lactobacillus casei, or Actinomyces viscosus, and the size of inhibitory zone measured after 48h incubation. The results were compared with those obtained from the agar diffusion tests using paper discs containing each component before curing. The extent of curing of each adhesive system was also determined by measurement of the degree of conversion of combined specimens of primer and adhesive, and Knoop Hardness of the cured specimen's surface. Although the almost uncured components produced inhibitory zones, the cured specimens of LB, SC and IM showed no or little inhibition against all bacteria. TO showed inhibitory effect against A. viscosus even after being cured. The extent of curing of TO was the lowest among four specimens. These results indicate that the most of the tested dentine adhesive systems lost antibacterial activity after being cured and that the residual antibacterial activity of TO might be associated with the lower extent of curing seen with this material.
