Limpieza y desinfección de instrumental de uso odontológico que realizan estudiantes universitarios de un programa de odontología

Abstract

Introduction The oral cavity is considered a carrier of microorganisms, therefore the dental instruments upon contact with saliva and blood, becomes great carrier of these, making it necessary to implement protocols cleaning, disinfection and sterilization to eliminate microorganisms causing infectious diseases. Objective To evaluate cleaning and disinfection procedures carried out by university students to dental instruments. Methodology A analytical observational cross-sectional study was conducted with a population of 322 students from seventh to tenth semester of dental school. The sample was calculated with using the Epidat Version 4.0 program using a random non-probability sampling; resulting in the collection of 56 samples. variables such as gender, semester, type of clinic, use of biosafety, type of instrument, washing substance, substance disinfection and their respective times, turbidity test, microbial growth, bacterial morphology, compliance, effectiveness, evaluation protocols were evaluated, among other. The data were processed in the IBM SPSS Statistic 21 program, using percentages, frequencies and chi2 and Fisher exact test. Results Regarding the type of clinic, students with greater participation were the ninth semester 20 (36%), it was evident that some students made immersion in enzymatic soap less than 10 minutes 19 (33.9%); with respect to immersion in the disinfecting substance 45 (80.3%) did not use it; on the other hand 43 (76.7%) did not meet the use of biosafety. Finally microbial growth in instruments that did not meet the protocol proposed by the University 47 (84%) and more often morphology was obtained was that of Gram positive cocci.Conclusions The study achievement show that dental students do not fully comply with the process of washing with soap enzyme and glutaraldehyde disinfection process. The evaluation of the use of biosecurity barriers showed that most of the students did not use completely implements personal protection.
