Conference paper


The enamel surface layer of human teeth was treated with a Q-switched Nd:YAG laser with 8 mJ energy per pulse. Previously, the samples were etched, weakly, with acid in order to decrease their refletion. Treated and control samples were widely studied by scanning electron microscopy and, in the first ones, it was observed significant morphologic changes affecting the enamel surface. Those changes, principally, reveal the loss of the typical surface structure of the etched enamel. Further studies applaing knoop hardness measurements on cross-sections of the enamel samples confirm an increase of the demineralization resistance.
