Abstract

Bkgrounacd and Objective: The use of Excimer laser for the treatment of enamel and dentin surfaces has considerable potential because the combined characteristics of low wave length and short pulse result in limited heat diffusion and therefore tissue ablation without collateral damage. The Aim of this Work was to study the effect of XeCl Excimer laser 308 nm wave length on the mineral contents of human enamel and dentin surfaces. Materials and Methods: 12 lower anterior teeth were subjected to irradiation with 308 nm lambada: physik model optex excimer laser and XeCl fill, the effects created by laser application were assessed by X-Ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Results: laser treatment on both human enamel and dentin surfaces had positive effects as the spectrum of the laser treated surfaces appeared similar to the untreated surfaces.
