dc.description.abstract An evaluation was made of the sterilizing effects of the Erbium: YAG laser at different power ratings upon dental structures in vitro. An in vitro study was made of 47 single-root teeth removed for periodontal reasons in the Oral and Maxillofacial Surgery Teaching Unit (Department of Medicine and Orofacial Surgery, Madrid Complutense University Dental School, Spain). The teeth were divided into three laser irradiation groups (250, 350 and 450 mJ) and a non-irradiated control group. The teeth were then immersed in an enrichment medium for 72 hours under conditions of anaerobiosis, with visual controls after 24, 48 and 72 hours. Posteriorly, microbiological cultures were made in blood agar to confirm the results of the visual inspections. Increased percentage sterilization of the samples was recorded with increasing irradiation power - statistically significant differences being observed between all irradiated groups versus the controls. In conclusion, the Erbium: YAG laser exerts a sterilizing effect upon dental structures in vitro. This effect increases with increasing laser power ratings. spa
dc.description.abstract Nuestro objetivo era comprobar el efecto esterilizante del láser de Erbium: YAG, a diferentes potencias, en dientes in vitro. Se realizó un estudio in vitro sobre 47 dientes unirradiculares extraídos por motivos periodontales en la Unidad Docente de Cirugía Bucal y Maxilofacial (Departamento de Medicina y Cirugía Bucofacial) de la Facultad de Odontología de la Universidad Complutense de Madrid. Las muestras fueron divididas en tres grupos de irradiación con láser (250mJ, 350mJ y 450mJ) y un grupo control -no irradiados-. A continuación se introdujeron en un medio de enriquecimiento durante 72 horas en anaerobiosis, realizando controles visuales a las 24, 48 y 72 horas. Y posteriormente se realizaron cultivos microbiológicos en agar sangre, para confirmar los resultados de los controles visuales. Se observa como a medida que aumenta la potencia de irradiación con el láser hay un mayor porcentaje de esterilización de las muestras, existiendo diferencias estadísticamente significativas entre el grupo control y cualquiera de los grupos láser. En conclusión, el láser de Erbium: YAG presenta efecto esterilizante sobre las estructuras dentarias in vitro, que se va incrementando a medida que aumenta la potencia de aplicación del mismo. spa
