Effectiveness of Lysol and Glutaraldehyde 2 % in high-speed handpieces after being subjected to mechanical cleaning

Chemical disinfection is an important procedure used in the dental field that aims to prevent the spread of pathogenic microorganisms that may affect health. Objective: To determine the disinfectant effectiveness of the Lysol and Glutaraldehyde 2% agent in aerosol in high-speed handpieces in ninth semester students who attend the Integral Clinic of the School of Dentistry of the Central University of Ecuador (FO-UCE) period 2017. Materials and methods: In vitro experimental study. The sample was obtained from 40 high-speed handpieces before and after subjecting the turbines to a disinfection process using two agents applied in aerosolized Lysol and Glutaraldehyde 2%. The samples were taken from two sites, head and handle. The samples were then transported to the FO-UCE Microbiology laboratory in tubes with thioglycolate, subsequently seeded in the blood agar medium and incubated for 48 hours at 37 ° to finally observe the formation of colony forming units. The statistical analyzes of ANOVA and Tukey with a significance level of 5% were used. Results: An effect on the bacterial reduction of 0.6 CFU glutaraldehyde and 1.3 CFU lysol was observed after use. Both glutaraldehyde and lysol showed significant differences before and after use (p <0.001), with no differences between the two after mechanical disinfection with both aerosol substances (p = 1.0). Conclusion: Glutaraldehyde and Lysol aerosol were effective in disinfecting high speed handpieces.
