Resumen
En la actualidad se ha capacidad que tienen las amalgamas y de los nuevos materiales de obturación como es la composita de nanoparticulas para brindar por si solas un sellado marginal que evite la producción de la microfiltración entre el diente y la restauración.
Este estudio nos servirá para comprobar el grado de microfiltración que se producen en este tipo de restauraciones en cavidades clase I de Black usando como materiales la composita de nano partículas fotopolimerizable y la amalgama de plata.
En el estudio in vitro se prepararon cavidades clase I en 30 piezas dentarias sanas, tanto molares como premolares . Estas piezas dentarias fueron divididas en dos grupos la cuales quince fueron obturadas con composita de nanoparticulas y el otro grupo de quince piezas fueron obturadas con amalgama de plata.
El objetivo de nuestra investigación se basa en comprobar el sellado marginal que presentan estos materiales y el nivel de grado de microfiltración que existe al no tener un buen sellado marginal va acarrear varios problemas a futuro como es el de caries debido a la brecha que existe entre diente y material restaurador, este estudio aportara con conocimientos sobre estos 2 materiales en el campo estudiantil y odontológico
Today has been discussed about the ability of amalgam and new filling materials as nanoparticles composita is to provide for themselves a marginal seal that prevents the production of microleakage between the tooth and the restoration. This study will help us to assess the degree of microleakage occurring in these restorations in class I cavities using as materials the Black composita photopolymerizable nano particles and silver amalgam. In the in vitro study class I cavities were prepared in 30 parts healthy teeth, both molars and premolars. These teeth were divided into two groups the fifteen which were sealed with composita nanoparticles and the other group of fifteen pieces were sealed with amalgam. The goal of our research is based on checking the marginal sealing of these materials and grade level microfiltration there not having a good marginal seal will cause several problems in the future such as cavities due to the gap between tooth and restorative material, this study furnish with knowledge on these 2 items on student and dental field.
