Resumen

Stomatological practice demands a high biosafety risk due to the presence of pathogenic agents due to the production of aerosols during procedures, thus urging the implementation of a disinfection means such as Thermonebulisation to significantly eliminate microorganisms, The aim of this research was to compare the effectiveness of two disinfectant substances through thermonebulisation (quaternary ammonium and glutaraldehyde), 20 sterile swab samples from surfaces in public and private dental offices were used, the procedure was performed through thermonebulisation in a period of 5 min, and the sampling was done past the hour and a half of thermonebulisation, which were taken through Stuart transport for preservation, the samples were distributed in two groups of 10 for each disinfectant, where each 90 ml of disinfectant counted with 160 ml of distilled water, 160 ml of liquid glycerin,160 mml of industrial alcohol, It was found that in a thermonebulisation process there is greater effectiveness for quaternary ammonium with a confidence level of 100% due to the total elimination of colony-forming units of microorganisms, while glutaraldehyde only reduced the microbial load, It is concluded that quaternary ammonium proved to be more effective for the disinfection of the dental practice in contrast to glutaraldehyde.
