Abstract

The present paper summarizes the results of a study of the morphological, structural and compositional changes caused on dentin by processing with KrF excimer laser (λ= 248 nm). Different surface textures are achieved depending on the structure of the samples and on the processing parameters. Independently of the radiation fluence used, a significant reduction of the organic material content is observed in a surface layer a few nanometers thick, but no significant changes in the mineral phase occur.
