Antibacterial action of various denture base resins on thirteen species of bacteria were studied in vitro. Antibacterial effect of 5% tannin-fluoride preparation, 5% tannic acid and 5% chlorhexidine added to resins on these thirteen bacterial species were also investigated using heat-curing denture base resins. Fresh microwave-curing resin and pour-type resin each showed an antibacterial action on one bacterial strain. Fresh self-curing resins had antibacterial actions on several bacterial strains. However, after storage in water at 37 degrees C for one week, antibacterial action of microwave-curing and pour-type resin were diminished and self-curing resins partially lost their antibacterial actions. Denture base resin containing tannin-fluoride preparation or tannic acid showed an antibacterial effect on one bacterial strain. On the other hand, denture base resin containing chlorhexidine had an antibacterial action on eleven bacterial strains. However, color and mechanical properties of the drug-containing resins were not satisfactory.
体外研究了各种义齿基托树脂对13种细菌的抗菌作用。还使用热固化义齿基托树脂研究了添加到树脂中的5%单宁氟制剂、5%单宁酸和5%氯己定对这13种细菌的抗菌效果。新鲜的微波固化树脂和灌注型树脂对一种细菌菌株均表现出抗菌作用。新鲜的自凝树脂对几种细菌菌株有抗菌作用。然而，在37℃水中储存一周后，微波固化树脂和灌注型树脂的抗菌作用减弱，自凝树脂部分失去其抗菌作用。含单宁氟制剂或单宁酸的义齿基托树脂对一种细菌菌株有抗菌作用。另一方面，含氯己定的义齿基托树脂对11种细菌菌株有抗菌作用。然而，含药树脂的颜色和机械性能并不理想。
