Evaluación de la contaminación microbiana en las resinas compuestas utilizadas por los estudiantes de la carrera de odontología de la UCSG.

Abstract

INTRODUCTION: Composite resins, which are one of the most widely used materials in dental practice, do not have international measures for their handling, nor for their procedures in terms of disinfection standards. OBJECTIVE: demonstrate if there is microbial contamination in the composite resins used by the students of the UCSG Dentistry career. MATERIALS AND METHODS: The research is of a qualitative-quantitative approach of an experimental and cross-sectional descriptive type, it was carried out by means of a sample of 50 resins used by the students of the Catholic University of Santiago de Guayaquil, of the Dentistry Career. ANALYSIS AND DISCUSSION OF RESULTS: Regarding the results obtained, it was possible to verify that 10 of the resin tubes used by the students were contaminated by various pathogens, these being 80% bacteria with a predominance of Staphylococcus sapr and 20% fungi. such as Aspergillus spp. and Rhizopus spp. CONCLUSION: The microbial contamination of 20% of the composite resin tubes used by the students of the UCSG Dentistry Clinic was confirmed. This contamination may be related to defects in the biosafety procedures used by the students, as well as in the storage process. It was verified that the time of use of the material influences a greater risk of contamination. Despite the good condition of the resin syringes, isolated pathogens were found in them. Finally, among the isolated microorganisms, Staphylococcus sapr stood out.
