Resumen
[Espa?ol] Las impresiones dentales tomadas en los consultorios odontol?gicos y enviadas al laboratorio dental son potencialmente un veh?culo para la contaminaci?n cruzada. La investigaci?n ha demostrado que a pesar de la evidencia sobre la importancia de la desinfecci?n de las impresiones dentales, con diferentes protocolos y productos para este uso, los odont?logos todav?a no desinfectan correctamente las impresiones antes de enviarlas a los t?cnicos. Este estudio tiene como objetivo describir y evaluar la efectividad de diferentes espr?is desinfectantes que son utilizados para este prop?sito y tambi?n determinar si el protocolo establecido por la Maestr?a en rehabilitaci?n bucal e implantes dentales de UNIBE es adecuada. Veinte impresiones dentales fueron tomadas en cubetas est?riles con silicona y luego fueron divididas en dos grupos; el primer grupo fue desinfectado con Lysol IC y el segundo grupo con Zeta 7 Spray. Se tomaron muestras de cada impresi?n antes y despu?s de la desinfecci?n y las mismas fueron sembradas en un medio de cultivo anaerobio para observar el crecimiento bacteriano. El an?lisis del crecimiento bacteriano luego de la desinfecci?n confirm? que ambos grupos eran efectivos en la desinfecci?n de impresiones. Los resultados indican que ambos grupos pueden ser utilizados para la desinfecci?n de impresiones eficientemente. En base a esto, se recomienda que el dentista se asegure que las impresiones dentales sean sometidas a un proceso de desinfecci?n apropiado en el consultorio o la cl?nica comunitaria. Tambi?n se recomienda comunicarle al t?cnico dental el protocolo utilizado para la desinfecci?n. Se necesita m?s investigaci?n para comparar las diferentes t?cnicas de desinfecci?n con muestras m?s grandes y evaluar otros factores que pueden influir en la desinfecci?n de impresiones. [English] The dental impressions taken at the dental office and usually delivered to dental laboratories are a potential vehicle for cross contamination. Research has shown that despite the evidence of how important is the disinfection of dental impressions, with several protocols and products for this purpose, clinicians still don?t disinfect their impressions properly before sending them to the technicians. This study aims to describe and evaluate the effectiveness of different disinfectant sprays that are used for this purpose and also to determine if the protocol established by UNIBE?s Master of Science in oral rehabilitation and dental implants is adequate. Twenty dental impressions were taken in sterile trays with silicone, and later divided in two groups; the first group was disinfected with Lysol IC and the second group with Zeta 7 Spray. Samples were taken from each impression before and after the disinfection and were later grown in anaerobic culture mediums to observe the growth of bacteria. Analysis of the growth of bacteria after disinfection confirmed that both groups were effective in the disinfection of impressions. The results indicate that both groups can be used for the disinfection of impression efficiently. On this basis, it is recommended that the dentist itself makes sure that dental impressions undergo disinfection properly at their office or the community clinic. It is also recommended to communicate to the dental technician the protocol used for disinfection. Further research is needed to compare different disinfecting techniques with larger samples and to evaluate other factors that could influence the disinfection of dental impressions.
