Effect of Chemical Disinfectants in Complete Dentures- A Comparative Study

Abstract

Aim

Purpose of our research was to compare and evaluate various chemical disinfectants used to cleanse complete dentures.

Methodology

Forty-five edentulous patients wearing dentures were divided into three categories: Group I disinfected their dentures by immersing in 0.2% chlorhexidine gluconate solution for 30 mins twice a week and Group II used 1 percent sodiumhypochlorite solution for 30 mins twice a week. for immersion, Group III had a positive control group consisting of dentures that were not disinfected. The inter-molar distance was measured with Digital Vernier calipers.

Results

Group I showed highest decline in number of bacterial colonies after 60 days followed by Group II. Least decline was seen in III. Highest dimensional changes was seen in Group I followed by Group II dentures.

Conclusion

Soaking in sodium hypochlorite solution was effective only as a short-term disinfectant as compared to Soaking in chlorhexidine gluconate solution.
