Resumo
This study evaluated the change that occurs in dental enamel under action of oven heating or
Er,Cr:YSGG laser irradiation aiming to obtain a structure more resistant to demineralization. Enamel pow
der was obtained from bovine teeth. Samples were subjected to oven heating at temperatures of 200, 400, 600,
800, and 1000°C or during laser irradiation with energy densities of 7.53, 10.95, and 13.74 J/cm2
. The infra
red thermography was used to measure the surface temperature generated in the solid samples of enamel dur
ing lasers irradiation. The samples were analyzed by Fourier transform infrared spectroscopy (FTIR), which
shows changes on enamel oven heated or laser irradiated, due to treatments, related to carbonates, adsorbed
water and hydroxyl content. These compositional effects were more evident in lased samples. These changes
may alter the material properties such as its solubility, and decrese of demineralization that is important for
caries prevention.
