title: Analysis of the effectiveness of different hygiene procedures used in dental prostheses.
abstract: OBJECTIVE
  To compare the effectiveness of bacterial plaque removal of six denture hygiene procedures used by patients to clean their dentures.
  
  
  METHODS
  Fifteen students randomly divided into groups G1, G2, G3, G4, G5 and G6 used maxillary intraoral appliances for 24 h without cleaning them. Afterwards, the appliances were submitted to the following procedures: P1: washing under running water for 20 s; P2 and P3: cleaning with alkaline peroxide (Corega Tabs®) for 5 and 30 min, respectively; P4: brushing with water and liquid soap for 40 s; P5: alkaline hypochlorite for 10 minutes; P6: home use chlorine solution (Q'boa® at 0.45% for 10 min), throughout a period of 6 consecutive weeks. The procedures followed a circulating scheme, so that all the appliances were submitted to all the hygiene methods studied. After the hygiene procedures, the appliances were stained, photographed and submitted to the weighing method.
  
  
  RESULTS
  After ANOVA and Tukey's test, differences were observed: P5 = 0.73 ± 0.3 (b), P6 = 1.27 ± 0.4(b,c), P4 = 1.92 ± 0.5 (b,c), P3 = 2.24 ± 1.0 (b,c), P2 = 7.53 ± 2.5 (c) and P1 = 26.86 ± 15. 3 (a).
  
  
  CONCLUSIONS
  From the results of the study, it could be concluded that the use of alkaline hypochlorite is the best way to remove bacterial plaque, followed by the home-use chlorine solution and brushing with water and liquid soap. Corega Tabs® must be used for 30 min of immersion to have a cleaning effectiveness similar to that of alkaline hypochlorite.
