Objective: Determine the bacterial microorganisms present in sprays originated by dental handpieces according to it´s location and time spent on Clinica Docente de la UPC´s environment. Materials and methods: A total of 90 blood agar plates were used in three groups of 30 plates each. The first group consisted of 30 control plates that were exposed before the opening of the clinical shift and without contact with patients. The second group also consisted of 30 plaques that were exposed to the aerosols for fifteen minutes. Two plates were used for each dental unit, located in two different sites. One plaque was placed in the lavatory and the other on the patient's breast. The third group of plaques were exposed under the same protocol, but for 120 minutes. Subsequently, counts of Colony Forming Units (UFC), Gram staining and identification tests were performed, with the objective of identifying the genus of microorganisms in the oral cavity. Results: Most bacteria found are Gram positive belonging to Staphylococcus spp and Streptococcus spp. Conclusions: There is more bacterial contamination near a rotating instrument and a longer time of its use.
