7 September 1994 Morphological changes of dentin and enamel after ablation with an experimental laser system

Erbium lasers have previously demonstrated their capabilities as dental hard tissue ablators. Phase changes in the crystalline structures of enamel and dentin appear not to have been produced by the erbium 2.94 micrometers laser radiation. However, the detailed ablation mechanism is still not understood. A hypothesis proposed by some authors is that hard tissue removal is in part by a continuous vaporization process and in part by microexplosions. In an attempt to better understand the ablative processes we have employed different observational instruments and techniques to characterize and identify the morphological changes taking place. The purpose of this study was to develop an understanding of the morphological changes of dentin and enamel that occur after ablation with an experimental erbium laser system.
