Resumo

Lasers are used for preventing demineralization, but there are no studies that report the compositional changes on root dentin irradiated with Er,Cr:YSGG (2.78 mu m) laser in an erosive process. In this in vitro study, fifty dentin slabs were distributed in 5 groups to be treated with Er,Cr:YSGG laser associated or not with application of acidulated phosphate fluoride gel (APF-gel); then, a 10-days erosion regimen was conducted and the composition changes were monitored by Fourier transform infrared spectroscopy. The data suggest a synergistic effect between laser irradiation and APF-gel, with a greater preventive effect when APF-gel was applied after irradiation. (AU)
