Protective effect of anti-erosive solutions enhanced by an aminomethacrylate copolymer.

摘要: Abstract Objective To investigate if an aminomethacrylate copolymer (AMC) could potentiate the anti-erosive effect of solutions containing sodium fluoride -F (225 ppm F−) and associated to stannous chloride -FS (800 ppm Sn2+). Methods The experimental (F, FS, AMC, AMC + F, AMC + FS, deionized water-DW as negative control) were tested in presence acquired pellicle. Polished bovine enamel specimens (n = 13/group) submitted erosion-rehardening cycle (2 h immersion human saliva, 5 min 0.3 % citric acid, 1 h 4×/day, 5 days). Treatment with was performed for 2 min, 2×/day. rehardening (%Re) protective (%Prot) potential assessed beginning experiment, surface loss (SL) by contact profilometry after days. Additional (n = 5/group) prepared evaluate angle on treated surface. zeta dispersed hydroxyapatite (HA) crystals treatment also measured (n = 3/group). Data statistically analyzed (α = 0.05). Results association AMC improved %Re %Prot W F, but not FS. results SL were: AMC + F = AMC + FS  Conclusion has enhance solutions. Clinical significance may be a promising agent added oral care products prevention erosive tooth wear.
