Anti-erosive properties of solutions containing fluoride and different film-forming agents

Influence of Toothbrushing on the Antierosive Effect of Film-Forming Agents

“…A reduction in efficacy of this solution was only observed after 100 strokes of brushing. The antierosive action of the F+LPP solution could be related to a complementary protection of both agents, F by the formation of CaF 2 -like precipitates and LPP by adsorbing onto the remaining available positive sites, creating a more resistant barrier against dissolution [Scaramucci et al, 2015]. LPP is a polyphosphate with a linear chain, which is widely used as meat preservative or additive of nonalcoholic-flavored drinks [Barbour et al, 2005].…”

“…The synergistic effect between F and Sn is thought to be associated with the deposition of acid-resistant metal-rich precipitates on the tooth surfaces and the incorporation of Sn and F into the tooth structure [Babcock et al, 1978;Ganss et al, 2010a]. Another preventive approach with promising results is the association of F with some film-forming polymers, such as polyphosphates [Manarelli et al, 2011;Scaramucci et al, 2015]. These polymers can adsorb to the dental surfaces, creating a layer that would protect the underlying tooth structure against demineralization [Barbour et al, 2005;Scaramucci et al, 2011].…”

“…These polymers can adsorb to the dental surfaces, creating a layer that would protect the underlying tooth structure against demineralization [Barbour et al, 2005;Scaramucci et al, 2011]. In a previous in vitro investigation, we have shown that sodium linear polyphosphate (LPP) enhances the protection of F and Sn against enamel erosion, possibly by creating an even more acid-resistant layer at the tooth surface [Scaramucci et al, 2015]. In this study, under highly erosive simulated conditions, a solution containing 225 ppm F (as NaF), 800 ppm Sn (as SnCl 2 ), and 2% LPP reduced enamel loss further than a solution containing only F and Sn.…”

“…All solutions had their pH adjusted to 4.5 with either KOH or HCl solutions to eliminate pH as a confounding factor. The Sn-containing solutions were stabilized by adding 2.3 g/l of gluconic acid sodium salt (Acros Organics, Geel, Belgium) Scaramucci et al, 2015].…”

“…Enamel and root dentin specimens (4 × 4 × 2 mm) were sectioned from the crowns and the roots of the bovine teeth, respectively, embedded in acrylic resin, flattened and polished as described previously [Scaramucci et al, 2015]. Adhesive UPVC (unplasticized polyvinyl chloride) tapes were placed on the polished surface of each specimen, leaving an area of 4 × 1 mm 2 exposed to subsequent testing.…”
