Antimicrobial Efficacy of Peracetic Acid for Dental Impression Disinfection

80 dental impressions from volunteers were used to evaluate the antimicrobial effectiveness of 0.2% peracetic acid and 1% sodium hypochlorite using nebulization and spray techniques. The study, authored by Carmem Dolores Vilarinho Soares de Moura, found a statistically significant reduction in bacterial colonies compared to controls. Results indicated nebulization with 0.2% peracetic acid was more effective than 1% sodium hypochlorite.

Use Cases

• Compare the efficacy of nebulization versus spray disinfection methods based on the described experimental design.
• Evaluate the antimicrobial performance of 0.2% peracetic acid against 1% sodium hypochlorite based on the reported p-values.
• Analyze the relationship between disinfection method and bacterial colony count reduction based on the microbiological analysis results.

Strengths

• The study design includes 80 impressions divided into four experimental groups with controls.
• Results are supported by specific statistical significance values (e.g., p<0.05, p=0.030).
• The description details the specific disinfection agents, concentrations (0.2%, 1%), and exposure time (10 minutes).
