Many reports have pointed out that Candida albicans (C. albicans) is one of the main causative factors of denture stomatitis. Test denture polymers containing an antibacterial (A-B) agent were developed for the prevention of denture stomatitis. Bacteriostatic activity of A-B agents against C. albicans and the effects of A-B agents on mechanical properties were investigated in this study. A-B agent was contaminated and immersed in the conventional heat-cured denture base resin polymer as 1, 3, 5, and 7 wt% respectively. The flexural strength test, knoop hardness test, linear shrinkage measurement, and water absorption measurement were performed. The colonies of C. albicans were counted on the Glucose peptone agar with Lecithin & Polysorbate 80 agar preparations on the thermal test pieces.<BR>The results were as follows: All mechanical properties were hardly influenced when any percentage of AB agents (p>0.05) was contained. Bacteriostasis was clearly observed in the test polymers containing over 3% A-B agent. The minimum percentage of A-B agent that does not degrade the denture polymers was considered to be 3%.
