Fourteen dentures from patients requiring new dentures were cultured, treated with Clorox/Cascade/H2O solution, Brushgard, Polident, or distilled water and re-cultured. All fourteen dentures were contaminated with multiple microorganisms. The Clorox/Cascade/H2O solution was most effective at decontamination with 71% of the treated dentures showing no growth of microorganisms. Brushgard showed no growth in 57%; Polident showed no growth in 36%; and water showed no growth in 14%. 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副需要新假牙的患者的假牙进行培养，用高乐氏清洁剂/佳洁士/水混合溶液、Brushgard、Polident或蒸馏水进行处理后再培养。所有14副假牙都被多种微生物污染。高乐氏清洁剂/佳洁士/水混合溶液的去污效果最佳，71%经过处理的假牙没有微生物生长。Brushgard处理的假牙中有57%没有微生物生长；Polident处理的假牙中有36%没有微生物生长；水冲洗的假牙中有14%没有微生物生长。值得注意的是，经Brushgard、Polident和水冲洗处理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。这项研究的结果表明，目前市场上没有一种产品能够始终如一地对假牙深处进行消毒。
