Effect of Titanium Tetrafluoride and Amine Fluoride Treatment Combined with Carbon Dioxide Laser Irradiation on Enamel and Dentin Erosion

Potential of CO2 lasers (10.6 µm) associated with fluorides in inhibiting human enamel erosion

“…Although it was expected that CO 2 laser irradiation would increase the efficacy of fluoride, as shown in this previous studies performing cariogenic challenges, in the present report, CO 2 laser irradiation did not significantly increase the effects of either fluoride agents (AmF and NaF) on erosion. Corroborating our results, Wiegand et al 12 reported that AmF was able to decrease enamel erosion, but CO 2 laser irradiation did not improve its efficacy. …”

“…8,9,10 Furthermore, some authors have concluded that laser irradiation associated with fluoride agents 11,12 could increase the fluoride uptake into the enamel, making the enamel more acid resistant. 11,13 However, until now, there have been only a few studies 12,14,15,16 evaluating the use of CO 2 lasers to prevent dental erosion, and these studies have been inconclusive.…”

“…The anti-erosive effects of these fluoridated agents could be justified by the formation of a layer of spherical CaF precipitates on the enamel surface following topical application, 6,17 acting as a reservoir of fluoride ions to inducing the formation of fluorapatite or as a physical barrier isolating the enamel surface from further acid attacks, thus preventing demineralization. 12,27 Regarding the use of high-power lasers, previous in vitro studies have shown promising results with CO 2 laser in enhancing the acid resistance of enamel during cariogenic challenges. 9,13 Featherstone et al 8 reported that CO 2 laser produced radiation in the infrared region, which coincided closely with the phosphate absorption band.…”

“…Some authors have studied the effects of laser irradiation combined with fluorides on enamel demineralization 11,12 and have concluded that there was some significant synergism between treatments. Although it was expected that CO 2 laser irradiation would increase the efficacy of fluoride, as shown in this previous studies performing cariogenic challenges, in the present report, CO 2 laser irradiation did not significantly increase the effects of either fluoride agents (AmF and NaF) on erosion.…”

Prevention of Enamel Adjacent to Bracket Demineralization Following Carbon Dioxide Laser Radiation and Titanium Tetra Fluoride Solution Treatment: An In Vitro Study

“…The preventive potential of TiF4 against dental demineralization is related to the formation of an acid-resistant surface coating, the increased fluoride uptake and also the titanium incorporation in the hydroxyapatite lattice. [15][16][17][18][19][20][21] There are still very few studies investigating the caries-preventive effect of CO 2 laser and TiF4 together in which the synergistic effect of CO 2 laser and fluoride has been seen. 3,4,11 However, there are still no consensuses between the researchers on the mechanism of their action on each other.…”
