Summary
No denture cleaning product consistently disinfects dentures. A Clorox/Cascade/H2O solution was most effective, but no product eliminated all microorganisms from denture depths.
Area of Science:
- Microbiology
- Biomedical Engineering
- Dental Prosthetics
Background:
- Denture contamination is a common issue for patients requiring new dentures.
- Microbial growth on dentures can lead to oral health problems.
Purpose of the Study:
- To evaluate the effectiveness of common denture cleaning solutions in decontaminating dentures.
- To determine if any commercially available product can consistently disinfect denture depths.
Main Methods:
- Fourteen contaminated dentures were cultured.
- Dentures were treated with Clorox/Cascade/H2O solution, Brushgard, Polident, or distilled water.
- Re-culturing was performed to assess microbial growth.
Main Results:
- All fourteen dentures initially showed microbial contamination.
- The Clorox/Cascade/H2O solution resulted in no microbial growth in 71% of treated dentures.
- Brushgard (57%), Polident (36%), and water (14%) showed lower decontamination rates.
- Some treatments allowed the growth of different microorganisms.
Conclusions:
- No current market product consistently disinfects denture depths.
- The Clorox/Cascade/H2O solution demonstrated the highest efficacy among tested agents.
- Further research is needed for effective denture disinfection solutions.
