“…Many studies have shown the improved protection of solutions containing the combination F -+Sn 2+ in comparison with F -for preventing erosion [Schlueter et al, 2009a;Ganss et al, 2010a;Algarni et al, 2015aAlgarni et al, , 2015bScaramucci et al, 2015Scaramucci et al, , 2016. Nevertheless, in the present study, this effect was not so impressive.…”

“…These polymers have an affinity for, and adsorb to, dental surfaces, forming a protective barrier against erosive acids [Barbour et al, 2005]. Additionally, several studies have shown that some polymers can positively interact with fluorides, improving their protective action [Moretto et al, 2010;White et al, 2011;Scaramucci et al, 2015Scaramucci et al, , 2016Ávila et al, 2017]. Our in vitro data have shown that a linear chain sodium polyphosphate could increase the protection against erosion provided by a solution containing F -and Sn 2+ [Scaramucci et al, 2015], previously known to be effective against erosion [Huysmans et al, 2014].…”

“…Unplasticized polyvinyl chloride (UPVC) tapes were then placed on the polished surfaces of selected specimens, leaving a central window of 4 × 1 mm exposed for subsequent testing. [Scaramucci et al 2015[Scaramucci et al , 2016. The concentration of the film-forming polymers was determined in preliminary tests, for the purpose of matching the viscosity of a commercially available mouth rinse (Elmex Erosion Protection; GABA Schweiz AG, Colgate-Palmolive Co, Therwil, Switzerland, dynamic viscosity at 24° (mPa × s) = 0.98).…”

“…After collection, the saliva was pooled and immediately centrifuged at 14,000 g, at 4 ° C, for 20 min. The supernatant was separated from the pellet and stored at -80 ° C. The day before starting the experimental procedures, the amount of saliva needed was left to defrost overnight at 4 ° C. Two hours before cycling, the saliva pool was left at room temperature [Scaramucci et al, 2016].…”

“…Despite the many film-forming polymers and copolymers available in the dental industry field, only a few have been tested relative to their anti-erosive effects, especially in combination with other anti-erosion agents such as F - [Manarelli et al, 2011;do Amaral et al, 2016] and F -plus Sn 2+ Scaramucci et al, 2015Scaramucci et al, , 2016. This could open new possibilities in the development of oral health products that target the prevention of erosive tooth wear.…”

The aim of this study was to evaluate the anti-erosive effect of solutions containing sodium fluoride (F: 225 ppm F^–), stannous chloride (Sn: 800 ppm Sn2+), and some film-forming polymers (Gantrez: Poly [methylvinylether-alt-maleic anhydride]; PGA: propylene glycol alginate; Plasdone: poly[vinylpyrrolidone]; and CMC: carboxymethylcellulose). Solutions were tested in an erosion-remineralization cycling model, using enamel and dentin specimens (n = 10, for each substrate). Distilled water was the negative control. Cycling consisted of 120 min immersion in human saliva, 5 min in 0.3% citric acid solution, and 120 min of exposure to human saliva, 4×/day, for 5 days. Treatment with solutions (pH = 4.5) was carried out 2×/day, for 2 min. Surface loss (SL) was evaluated with optical profilometry. Zeta potential of hydroxyapatite crystals was determined after treatment with the solutions. Data were statistically analyzed (α = 0.05). For enamel, all polymers showed significantly lower SL (in µm) than the control (11.09 ± 0.94), except PGA (10.15 ± 1.25). PGA significantly improved the protective effect of F (4.24 ± 0.97 vs. 5.64 ± 1.60, respectively). None of the polymers increased the protection of F+Sn (5.13 ± 0.78). For dentin, only Gantrez (11.40 ± 0.97) significantly reduced SL when compared with the negative control (12.76 ± 0.75). No polymer was able to enhance the effect of F (6.28 ± 1.90) or F+Sn (7.21 ± 1.13). All fluoridated solutions demonstrated significantly lower SL values than the control for both substrates. Treatment of hydroxyapatite nanoparticles with all solutions resulted in more negative zeta potentials than those of the control, except Plasdone, PGA, and F+Sn+PGA, the latter two presenting the opposite effect. In conclusion, Gantrez, Plasdone, and CMC exhibited an anti-erosive effect on enamel. PGA increased the protection of F. For dentin, only Gantrez reduced erosion.

Objectives To investigate the effect of toothpastes on dentine surface loss and tubule occlusion, and the association of toothpasterelated factors to each of the outcomes. Materials and methods One hundred and sixty human dentine specimens were randomly distributed into 10 groups, according to different toothpastes. The specimens were submitted to artificial saliva (60 min), citric acid (3 min), and brushing abrasion (25 s; totalizing 2 min in toothpaste slurries). This was repeated five times and two outcome variables were analyzed: dentine surface loss (dSL; μm) and tubule occlusion by measurement of the total area of open tubules (Area-OT; μm 2 ). Data were analyzed with Kruskal-Wallis and Mann-Whitney tests (α = 0.05); bivariate and multivariate regressions were used to model the association of the chemical (pH, concentration of F − , Ca 2+ , and PO 4 3− and presence of Sn 2+ ) and physical (% weight of solid particles, particle size, and wettability) factors of the toothpastes to both outcome variables. Results Toothpastes caused different degrees of dSL and did not differ in Area-OT. All chemical and physical factors, except the presence of Sn 2+ , were associated with dSL (p < 0.001). Area-OT was associated only with the presence of Sn 2+ (p = 0.033). Conclusion Greater dSL was associated with lower pH, lower concentration of F − , higher concentration of Ca 2+ and PO 4 3− , greater % weight of solid particles, smaller particle size, and lesser wettability, whereas tubule occlusion was associated with the presence of Sn 2+ . Clinical relevance Depending on their chemical and physical composition, toothpastes will cause different degrees of dentine tubule occlusion and dentine surface loss. This could, in turn, modulate dentine hypersensitivity.

This study evaluated the combined effect of Nd:YAG laser irradiation and fluoridated gels containing photo absorbers against enamel erosion. Enamel specimens from bovine teeth were polished, eroded (10 min, with 1% citric acid, pH = 2.6), and randomly allocated into the experimental groups (n = 8), according to the different surface treatments: fluoridated gels (F: 9047 ppm F and F + Sn: 9047 ppm F and 3000 ppm Sn), with or without photo absorbers (E: erythrosine and MB: methylene blue), and associated or not with Nd:YAG laser irradiation (in contact; 0.5 W; 50 mJ; ~41.66 J/cm; 10 Hz; 40 s; pulse duration of 120 μs). A placebo gel (PLA) associated or not with laser was used as control. All gels had pH = 4.5 and were applied for 2 min. Laser irradiation was performed during gel application. The specimens were then submitted to a 5-day erosion-remineralization cycling model using 0.3% citric acid (pH = 2.6), 4×/day. Enamel surface loss (SL) was analyzed by optical profilometry in the end of the cycling (in μm). Data were analyzed by ANOVA and Tukey tests (α = 0.05). Means (SD) of SL for the groups were the following (different superscript letters imply significant difference among groups): PLA (21.02 ± 1.28), PLA + laser (19.20 ± 0.96), laser (17.47 ± 1.50), F + Sn + E + laser (13.69 ± 0.62), F + E + laser (13.52 ± 1.16), F (13.10 ± 1.08), F + laser (11.94 ± 1.44), F + Sn + MB + laser (11.90 ± 4.02), F + MB + laser (11.42 ± 1.42), F + Sn (11.12 ± 1.20), and F + Sn + laser (10.35 ± 0.89). In conclusion, all fluoridated gels and the Nd:YAG laser irradiation reduced erosion development, but the combination of treatments did not promote further protection. The addition of photo absorbers to the fluoridated gels did not influence the anti-erosive effect of the combination of laser plus fluoridated gels.
