Abstract
Conventional dental lasers have not realized a selective excavation of carious dentin. Objective of this study is to determine the optimal irradiation condition for the selective excavation by using a wavelength around 5.8 μm. A nanosecond pulsed laser with a wavelength of 5.8 μm was obtained by difference-frequency generation technique. The laser delivers 5 ns pulse width at a repetition rate of 10 Hz. 5.8 μm wavelength range, a short wavelength required high excavation energy and a long wavelength required low excavation energy to induce the selective excavation with a low thermal side effect. 5.8 μm wavelength provides a selective excavation technique for minimal intervention.
