Abstract

Wavelength tunable free electron laser, FEL, was applied to analyze efficacy and mechanism of laser ablation for dental hard tissues. Irradiation of LEBRA-FEL, Nihon University, on the tooth sections at the wavelength range from 2.0 to 6.0 μm, the wavelength-dependency and also tissue-specificity were clearly observed. Observation during the pit formation by the irradiation, it was suggested the ablation being a type of plasma ablation.
