Primary Outcome Measures:
  • Microorganisms reduction [ Time Frame: Baseline, 30, 60 and 90 days ]
    Quantitative analysis of total microorganisms and Candida spp. Samples for culture were collected from dentures and saliva.

  • Changes in base acrylic resin [ Time Frame: Baseline, 30, 60 and 90 days ]
    Color stability and surface roughness evaluation

Secondary Outcome Measures:
  • Patients' satisfaction with the denture cleaning protocol [ Time Frame: 30, 60 and 90 days ]

Enrollment: 15
Study Start Date: August 2011
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Sodium hypochlorite immersion
    Dentures daily immersion in a 0.5% sodium hypochlorite solution for 3 minutes.
Detailed Description:
Considering that it is necessary to stipulate a simple and effective routine protocol for denture cleaning the aim of this study was to evaluate, in vivo, the efficacy of 0.5% sodium hypochlorite (NaOCl) as a denture cleanser and its effect on color stability and surface roughness of complete dentures. The patients' satisfaction with the denture cleaning method was also assessed.
