ABSTRACT
Introduction: Dental activity is exposed to a lot of microorganisms, and clinical interventions have a direct or indirect contact with them. Whether through the instruments, dental equipment contaminated with saliva, blood, etc; so you should take into account the type of contamination of handpieces for being the most widely used equipment for dental treatment. General Objectives: Determine the bacterial load in high-speed parts before and after being used in different clinical uses in Dentistry School at UV, Veracruz. Methodology: Cross-sectional, descriptive and observational research. Material and methods: 30 pieces of students from the Universidad Veracruzana School of Dentistry, Veracruz region, which a sample was taken with a swab to pieces before and after use in dental practice were randomly selected. Cultures with samples obtained observed during three days in a row microscope to determine the presence of bacterial colonies were made. Results: Of the 30 pieces before being used 24% of Bacillus Gram-positive samples were found; 20% Bacillus Gram-negative, Gram-positive Streptobacillus 6%; 20% Gram-positive Staphylococcus, 3% developed Coccobacillus Gram-negative and 22% Gram negative Actinomyces. The remaining 2% no colony forming units development (UFC). In a second sampling; 33% developed Bacillus Gram-positive, Gram-negative Bacillus 10%, 20% obtained Sthapylococcus Gram-positive, Gram-negative Sthapylococcus 3% and 34% did not develop colony forming unit (CFU). Conclusion: In the first sampling 98% of the pieces were microorganism growth, while in the second 66% and the presence of microorganisms obtained 34% no development.REFERENCES
