ABSTRACT
Debido a la reciente aparición de nuevas lámparas de fotopolimerización de alta intensidad y teniendo en cuenta los factores que influyen y los parámetros que determinan la eficacia de la polimerización se discute sobre los distintos tipos de lámparas. Los resultados obtenidos son inferiores en los de alta intensidad (arco de plasma y láser) a los valorados con lámparas halógenas. En cuanto a su evolución las LED son las mejor valoradas por sus ergonómicas ventajas (AU)
Due to the recent appearance of new lamps of photopolymerization of high intensity and considering the factors that influence and the parameters that determine the effectiveness of the curing it discusses on the different types from lamps. We've made a review of advantages and disadvantages for each light technology. We explain the main factors wich take importance in these procedures.The obtained results are poorer in those of high intensity (are of plasma and laser) to the valued ones with halogenous lamps. As far as their evolution the LED could be the right choice because of their ergonomic advantages. We expect a future with total compatibility between dental curing materials and lamps (AU)

In the last 40 years, magnets have been used in dentistry. Initially as anecdotic reports, but recently, after the development of powerful rare earth magnets, new applications of them have arised and offer a clinically proved alternative to mechanical systems. Many experimental and clinical trials have demonstrated their adequate use in prosthetic rehabilitations, partial removable or overdentures, tooth or implant beared, or in other like orthodontics. The authors describe the historical evolution of magnetic systems used in dentistry, their physical and mechanical principles, their attributes as biomaterials and their designs and way of use.
