The effectiveness of 3% h drogen peroxide, 5% chloramine T and 0,5% chlorhexidine gluconate solutions in disinfection of acrylic resine plates massively infected with oral flora was analysed. The acrylic resine plates used for investigations, were infected in vitro with mixed salivary flora characterized by small numbers of yeast-like fungi (1st group), or great number of these microorganisms (2nd group). Infected plates were exposed to solutions of analysed disinfectants during various time periods. After rinsing or inactivation of disinfectant residues, acrylic plates were put into bacteriological medium and incubated during 7 days period in 37 degrees C. The results of this study indicated the effectiveness of acrylic plates disinfection to be dependent on used disinfectant, time of exposition, and microorganisms present on the surface of acrylic resine. The solutions of disinfectants were less active in the cases of plates infected with material containing great numbers of yeast-like microorganisms. Among analysed disinfectants 0,5% solution of chlorhexidine was characterized by most effective and rapid activity, whereas 3% solution of hydrogen peroxide was found to be the least effective.
分析了3%过氧化氢、5%氯胺T和0.5%葡萄糖酸氯己定溶液对大量感染口腔菌群的丙烯酸树脂板的消毒效果。用于研究的丙烯酸树脂板在体外被以少量酵母样真菌为特征的混合唾液菌群感染（第1组），或以大量此类微生物为特征的混合唾液菌群感染（第2组）。将感染的板在不同时间段暴露于分析的消毒剂溶液中。在冲洗或使消毒剂残留失活后，将丙烯酸板放入细菌培养基中，并在37℃下培养7天。本研究结果表明，丙烯酸板消毒效果取决于所用消毒剂、暴露时间以及丙烯酸树脂表面存在的微生物。在感染含有大量酵母样微生物材料的板的情况下，消毒剂溶液的活性较低。在所分析的消毒剂中，0.5%葡萄糖酸氯己定溶液具有最有效和快速的活性，而3%过氧化氢溶液被发现效果最差。
