本研究的目的是量化生物膜上的内表面上的全口义齿后，六种可能的清洁方法。对36名无牙颌受试者进行了时间序列试验，并根据六种方法清洗义齿：（i）用水冲洗;（ii）在碱性过氧化氢溶液中浸泡（Bonyplus）;（iii）用柠檬酸盐刷牙（Dentu-Creme）和软约翰逊和约翰逊牙刷;（iv）根据方法2和3的浸泡和刷洗之间的组合;（v）用牙膏（Dentu-Creme）和柔软的口腔B牙刷刷牙;（vi）根据方法2和5组合浸泡和刷牙。每种方法在21天内随机使用。用1%中性红溶液对附着生物膜进行曝光，并通过内表面拍摄的数码照片进行定量。6种方法在生物膜覆盖率方面存在显著差异（重复测量ANOVA，P < 0.0001）。方法I的结果最高，2为中等，其他结果最低。最有效的方法是6。Biofilrn倾向于主要积聚在义齿基托的特定区域，但无论采用何种方法，这种模式都没有改变。可以得出结论，单独刷牙比所采用的化学方法更有效。最好的结果是通过组合的方法。
The aim of this study was to quantify biofilm on the internal surface of upper complete dentures following six possible cleansing methods. Thirty-six edentulous subjects were submitted to a time-series trial and dentures were cleansed according to six methods: (i) rinsing with water; (ii) soaking in an alkaline peroxide solution (Bonyplus); (iii) brushing with dentifrice (Dentu-Creme) and soft Johnson and Johnson's toothbrush; (iv) combination between soaking and brushing according to methods 2 and 3; (v) brushing with dentifrice (Dentu-Creme) and soft Oral B toothbrush; (vi) combination between soaking and brushing according to methods 2 and 5. Each method was randomly used throughout 21 days. Denture biofilm was disclosed by 1% neutral red solution and quantified by means of digital photos taken from the internal surface. The six methods presented significant differences in percentage of biofilm coverage (repeated measures ANOVA, P < 0.0001). Method I showed the highest values, 2 was intermediate and other results were the lowest. The most efficacious approach was 6. Biofilrn tended to accumulate predominantly over specific zones of the denture base, but this pattern did not change regardless of the method employed. It can be concluded that brushing alone was more effective than the chemical method employed. The best results were obtained by a combination of methods.
