Abstract		Optoacoustic measurements were carried out in order to obtain better understanding of the ablation mechanisms during the illumination of hard dental tissue by Er:YAG laser radiation. A broadband microphone was used to detect laser generated acoustic waves in the ambient air. Correlation analysis of the dental tissue independenly of the other spikes. This is in agreement with the model of ablation by means of micro explosions. The optoacoustic signal is observed to be approximately linearly related to the ablation efficency, and is thus demonstrated to be good measure of the ablation efficency. The experiments also show a significant difference in optoacoustic signals obtained during ablation in caries, enamel and dentin.
