Book Description
La sensibilidad dentinaria (SD) es un problema frecuente en la consulta dental. Para tratarla existen multiples opciones, entre las que destacan los adhesivos dentinarios que logran su efecto terapeutico formando una capa de material sobre la dentina expuesta y sellando sus tubulos. Las publicaciones sobre su efectividad presentan discrepancias. En los estudios de laboratorio muchos adhesivos parecen efectivos, sin embargo los resultados de los estudios clinicos son bastante peores, mostrando una efectividad limitada. Puede que esta discrepancia se deba a la dificultad que existe para reproducir las condiciones reales intraorales en los modelos de laboratorio usados hasta el momento. En este trabajo se presenta un sistema modificado de filtracion de muestras de dentina con el que se intenta reproducir la presion intrapulpar y con ello acercarnos un poco mas a las condiciones reales a las que estan sometidos los materiales cuando se aplican en boca sobre la dentina expuesta."

Book Description
Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.
