Resumen
El cobre ha sido parte importante en la vida y desarrollo de la sociedad durante miles de años. Se ha comprobado que dentro de las características de este elemento, se encuentra el ser un potente antimicrobiano y en este estudio observamos si existe una tendencia de este material de ser bactericida contra un microorganismo de la flora normal Enterococcus faecalis, el cual, en concentraciones descontroladas puede generar enfermedades a nivel sistémico y está dentro de las causantes de enfermedades intrahospitalarias, que en consecuencia, se traducen en grandes pérdidas monetarias al sistema de salud.
Este estudio se realizó mediante platinas de cobre que se adosaron a las superficies de mayor contacto dentro del box dental, en las que se compararon zonas sin revestimiento de cobre y zonas con revestimiento de cobre, antes y después de la atención odontológica diaria, en una toma mensual por dos meses. Se tomaron las muestras con hisopos estériles y fueron llevados inmediatamente a cultivo en medio apropiado para crecimiento de esta bacteria. Luego del cultivo se realizaron recuentos de colonias y se compararon los resultados de las superficies cobrizadas y las no cobrizadas, revisando si existe una disminución del crecimiento bacteriano.
Los resultados de este estudio mostraron que estadísticamente no era suficiente el tamaño de la muestra por lo que se necesitaría una mayor cantidad de recursos que los utilizados para este trabajo de investigación. Sin embargo, sirve como estudio piloto y marca una tendencia clara e importante a favor del efecto del cobre (si se toman los datos sin considerar el sesgo del tamaño de la muestra), mostrando una disminución de colonias en el crecimiento bacteriano en las superficies revestidas por el “material rojo”.
Copper has been an important part in life and development of society for thousands of years. It was found that among the characteristics of this element is being a potent antimicrobial and in this study we observed if there is a tendency for this material to be bactericidal against Enterococcus faecalis, a microorganism in the normal flora, which in uncontrolled concentrations can generate systemic diseases and is one of the causes of nosocomial diseases, which consequently results in large monetary losses to the health system. This study will be conducted through copper plates attached to larger contact surfaces in the dental box, comparing copper uncoated areas and copper coated areas before and after the daily dental care, in a monthly sample for two months. Samples were taken with sterile swabs and placed immediately into a cultivation medium that is suitable for bacterium growth. After cultivation, colony counts were performed and we compared the results of copper coated surfaces and copper uncoated surfaces, noticing if there is a reduction of bacterial growth.. The results of this study showed that the sample size used in this study was not statistically sufficient so that a greater amount of resources would be required. However, it serves as a pilot study and sets a clear and significant parameter in favor of copper effects (if the data is taken without considering the bias of the size of the sample), showing a decrease of colonies in bacterial growth on surfaces coated by the "red material".
