Fourteen dentures from patients requiring new dentures were cultured, treated with Clorox/Cascade/H2O solution, Brushgard, Polident, or distilled water and re-cultured. All 14 dentures were contaminated with multiple microorganisms. The Clorox/Cascade/H2O solution was most effective at decontamination with 71 percent of the treated dentures showing no growth of microorganisms. Brushguard showed no growth in 57 percent; Polident showed no growth in 36 percent; and water showed no growth in 14 percent. Of note, Brushgard, Polident, and water-treated dentures also allowed growth and predominance of other microorganisms that did not predominate on the original culture. The results of this study indicate that there is no product on the market at this time capable of consistently disinfecting the denture depths.
对14副来自需要新假牙患者的假牙进行培养，分别用高乐氏清洁剂/佳洁士/水混合溶液、Brushgard、Polident或蒸馏水进行处理，然后重新培养。所有14副假牙均被多种微生物污染。高乐氏清洁剂/佳洁士/水混合溶液在去污方面最有效，71%接受处理的假牙显示无微生物生长。Brushgard处理的假牙中有57%无微生物生长；Polident处理的假牙中有36%无微生物生长；蒸馏水清洗的假牙中有14%无微生物生长。值得注意的是，经Brushgard、Polident处理以及用水清洗的假牙还出现了在原始培养中不占优势的其他微生物的生长和占主导地位的情况。这项研究结果表明，目前市场上没有产品能够始终如一地对假牙深处进行消毒。
