Microorganismos presentes en las lámparas de luz de las unidades dentales de atención odontológicas

The dental practice services are provided to a large number of patients, and during the treatments performed aerosols are released that contain microorganisms that cause diseases, contaminating nearby surfaces. This study was carried out with the objective of determine which microorganisms are present in the cold light lamps of the dental units, to which part of it is the most contaminated, in the clinics of the National University of Loja, allowing to know if provides the necessary aseptic conditions to provide the dental service. This study was carried out before the dental care, during a week, three random days, Monday (clinic 1), Wednesday (clinic2) and Friday (Motupe). Four surfaces of the light lamp, handle, head, protector and ignition button were selected, which by means of swabbing and transported in stwuart medium, proceeded to the cultures processes for the identification of microorganisms. Sixty samples were taken and covered At 37 degrees Celsius on blood agar, and sabourand. Determinate that the head was the most contaminated part where 10% of the surfaces showed microbiological growth such as fungi; Aspergillus Spp 2.9%, Mucor 1.4%, Arthroderma Spp 0.7%, Antinomyces Spp 0.7%, bacteria; Streptomyces Spp 0.7% Nocardia 0.7%, and yeast; Penicillum 2.9%. The presence of microorganisms means that there is a lack of disinfection, and represents a minimal risk of cross infection, especially for patients with immunodeficiencies or uncontrolled diabetes, so a disinfection protocol was developed and socialized with the students. Keywords: microorganisms, cold light lamp, molds, fungi
