Studies have shown that dentine can be modified by pulsed CO laser to form a more acid-resistant substrate. This in vitro research aimed to evaluate the effect of CO laser, associated or not the topical application of fluoride in reducing demineralization of human root surfaces using a pulsed laser of wavelength 10.6 μm. Fifty human root surfaces obtained from twenty-five third molars were randomly divided into 5 groups (n=10) with the following surface treatments: G1 No treatment (negative control), G2 acidulated Phosphate Fluoride (FFA-positive control), G3 Laser 4.0 J/cm, G4 Laser 4.0 J/cm + FFA and G5 FFA + Laser 4.0 J/cm2. After surface treatment, specimens were subjected to 7 days of cycling the pH, remaining daily remineralizadora and demineralized in solutions for 21 h and 3 h, respectively. After acid challenge, the specimens were evaluated to determine the mineral loss through QLF. It can be concluded that the CO2 laser, with or without application of topical fluoride is able to inhibit the demineralization of root surface, however do not observed synergistic effect with the combination of laser irradiation and fluoride treatment.
