[Er:YAG laser: tissue interaction and histomorphological characterization]

Authors describe Er:YAG laser interaction with tissues, in particular their histomorphological characteristics to identify a specific clinic area for laser application through the examination of different clinical international trials. This study includes experimental trials about pig and rat skin laser application to know laser Er: YAG capability and limits; investigation is extended to laser application in human soft tissues as mucosa, periosteum and bones, its utility in cutaneous pathologies and in antiageing treatments.
