Abstract
The paper investigates the effects of UV laser irradiation on hard dental tissues. 12 sagittal cross sections 1 mm thick of teet extracted have been irradiated with pulsed ArF (A.=193 nm) and XeCl (A.=308 nm) excimer lasers. The beam has been focused to obtain a spot of about 1 mm on the enamel and dentin of the teet. The depth and the internal profile of the holes have been measured with a profilometer and correlated with the number of pulses and beam energy for each wavelength. No cracks were induced by thermal stresses nor preferential concentrations of Ca and F have been evidenced on the enamel and dentin after UV irradiation. These results show that the ablation of hard dental material can be successfully carried out with excimer laser irradiation without heat damage of the underlying tissues.
