ABSTRACT

Health professionals are exposed to a wide variety of microorganisms from spores, bacteria, fungi, viruses and protozoa that can be found in the blood and/or saliva of patients. Any of these microorganisms can cause an infectious disease through punctures and / or splashes produced by the aerosol during dental practice. Objective: To determine the bacterial presence in the high-speed pieces used in clinical practice. Material and methods: It are an experimental, observational and transversal study; where the contamination of 30 high-speed pieces used in clinical practice was evaluated. Prior to the study, a standardization was made obtaining a kappa of 0.85. A database was made in the program SPSS version 22, with which the descriptive analysis was carried out to determine measures of central tendency. Results: 73.3% of the analyzed samples showed bacterial growth, among the bacteria that were found, 54.5% of them were gram-positive bacteria and the rest were gram-negative. The bacterium with the highest presence in the sample was for Bacillus in 45.5% followed by Streptococcus in 27.3%, the remaining 27.2% was for Staphylococcus, Coccus and Streptobacillus. Conclusions: The correct use of the discharging parts, as well as their disinfection in the dental practice is of the utmost importance as they help us to avoid cross contamination and to prevent foci of infection from forming within the work area.
