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.openAccessdentistryerosionlaserslaser radiationfluoridesfourier transformationinfrared radiationTexto completo de evento10.1109/SBFOTONIOPC50774.2021.94619430000-0001-7404-9606https://orcid.org/0000-0001-7404-9606
