The antibacterial activity of newly-developed adhesive resin cement and primer on oral bacteria was investigated. Three types of adhesive resin cements and primers, and glass-ionomer cement as a control were used in the experiment.<I>S. mutans</I>ATCC 25175, <I>S. sanguis</I>ATCC 10556, <I>S. mitis</I>ATCC 3339, <I>S. salivarius</I>ATCC 25975, and<I>B. gingivalis</I>ATCC 3327 were used as test strains. Antibacterial activity of the resin cement immediately after mixing, after setting and after immersion in artificial saliva for one week were tested. A pH and fluoride release from resin setting were measured, and elute from settings was also measured by high-performance liquid chromatography.<BR>Most resin cements and primers showed antibacterial activity against the <I>Streptococci</I>, but did not show antibacterial activity against the <I>Bacteroides</I>. Primers and resin cement immediately after mixing showed greater antibacterial activity compared to the settings of resin after immersion of artificial saliva. A pH and fluoride release of settings of resin cement were not related to the antibacterial activity. HEMA, Mac-10, MDP and Bis-GMA were identified from settings and primers by high-performance liquid chromatography.<BR>The results suggested that the antibacterial activity was produced by the monomer of resin cement and primer.
