Eficacia in vitro de tres soluciones desinfectantes frente a microorganismos en pinzas mathew de ortodoncia

Abstract

Introduction: Using orthodontic pliers in daily practice confronts permanent contact with oral tissues different and the presence of microorganisms, which may be contaminating the pliers making them a potential health risk. Therefore, it`s required infection control process before, during and after patient care. Objective: The objective of this study was to evaluate the In vitro efficacy of three disinfectant solutions against microorganisms in Mathew orthodontic pliers. Materials and Methods: In vitro study was performed in Mathew orthodontic pliers. The specimen consisted of 60 pliers, which were subjected to processes of contamination with a medley of microorganisms (Enterococcus faecalis and Staphylococcus aureus), and disinfection with three substances: (Advanced EUCIDA® of Eufar®, alcohol 70% of JGB® and Bactidina® of Pharmaceutical Holandina of Colombia SAS). Statistical analysis was carried out using Shapiro Wilk test, Wilcoxon, Kruskal Wallis and Dunn multiple comparisons test. The criteria for the efficacy of each disinfectant were evaluated by measuring microbiological evidence UFC / mm2 quantitatively. Results: The reduction in CFU / mm2 for Enterococcus faecalis was higher with Bactidina® (Group II) (100%) and lower alcohol (Group III) (86.7%). In relation to Staphylococcus aureus was presented in the same way, the highest for the Bactidina® (Group II) (86.7%) and lowest for alcohol (Group III) (78.6%). Conclusions: Based on these results, the three disinfectant solutions are efficacious in reducing the bacterial load, but Bactidina® stands out as the most efficacious in removing contaminating agents
