A pulsed Er:YAG laser (2.94 pm) was used to determine ablation depths per pulse of laser energy at 2 Hz and 5 Hz in human teeth cross sections of enamel and dentin. Ablation depths per pulse at 2 Hz in enamel of intact human teeth were measured and compared to ablation depths per pulse determined in
__Objective:__ The purpose of this study is to make use of scanning electron microscopy in order to comparatively analyze the morphological alterations to human and bovine enamel and dentin. __Earlier data:__ Many a morphological study involving Er:YAG laser can be found in the literature. Still, no
## Abstract ## Background and Objectives Several studies of hard tissue ablation with Er:YAG lasers have shown that the addition of an optically thick water layer (โผ1 mm) added to the surface of dental enamel before each incident laser pulse, profoundly influences the rate and efficiency of ablati
