- ÍtemAcceso AbiertoContaminación bacteriana en el ambiente odontológico por la producción de aerosoles según el área de especialidad en los centros de especialidades odontológicas de Cuenca y Azogues de la Universidad Católica de Cuenca.(Universidad Católica de Cuenca., 2023) Zaruma Zhagñay, Nube Gabriela; Calderón Alemán, Doris Eliana; 09524500713; ., .The dentist, in daily practice, is exposed to a diversity of microorganisms generated by aerosols. Objective: To determine the degree of bacterial contamination in the dental environment due to aerosol production according to the specialty area in the dental specialty centers of Cuenca and Azogues at the dental clinics of the Catholic University of Cuenca (UCACUE by its Spanish acronym). Methods: The study was conducted in the UCACUE dental specialty clinics of UCACUE, Azogues, and the main campus. A stratified random sampling was performed, obtaining a sample of 72 dental units; 216 plates were used, placed on the patient's chest, the operator's face mask, and another in the spittoon. The enriched culture medium was kept open for thirty minutes while procedures such as operative dentistry, periodontics, and endodontics were developed. They were then incubated at 37°C under aerobic and anaerobic conditions for 24 hours each, and bacterial identification was performed using Gram staining. Results: As a result, 98.61% tested positive for bacterial growth. The highest average count of 354 CFU (Colony Forming Unit) was obtained in the periodontics area on the patient's chest at the Azogues campus, 62.16% of the identified bacteria corresponded to Gram-positive cocci. Conclusions: The degree of bacterial contamination produced by aerosols during dental treatment at UCACUE clinics was moderate, except in the operative area in the main campus, which was low. The highest concentration was found in periodontics on the patient's chest, predominating Gram-positive cocci of the Staphylococcus genus.
