“…Furthermore, fluoride was often added into the remineralization solution at higher concentrations than those found in human saliva (0.022 ppm) 49 because its profound effect on the enamel remineralization is well-established in the field. 34,61,62 It could be possible that the application of the more efficient remineralizing agents such as higher concentrations of fluoride and metal compounds (Sn 2þ , Ti 2þ ) 63 would result in the detection of erosion inhibition by reflection analysis.…”

Abstract. The present study assessed the effects of abrasion, salivary proteins, and measurement angle on the quantification of early dental erosion by the analysis of reflection intensities from enamel. Enamel from 184 caries-free human molars was used for in vitro erosion in citric acid (pH 3.6). Abrasion of the eroded enamel resulted in a 6% to 14% increase in the specular reflection intensity compared to only eroded enamel, and the reflection increase depended on the erosion degree. Nevertheless, monitoring of early erosion by reflection analysis was possible even in the abraded eroded teeth. The presence of the salivary pellicle induced up to 22% higher reflection intensities due to the smoothing of the eroded enamel by the adhered proteins. However, this measurement artifact could be significantly minimized (p < 0.05) by removing the pellicle layer with 3% NaOCl solution. Change of the measurement angles from 45 to 60 deg did not improve the sensitivity of the analysis at late erosion stages. The applicability of the method for monitoring the remineralization of eroded enamel remained unclear in a demineralization/remineralization cycling model of early dental erosion in vitro.

“…Thereby, SnF 2 containing toothpastes and solutions showed a better protective capability against erosion-like lesions than NaF agents. 10,11,23,24 Ganss et al 5 found that erosive mineral loss was nearly completely inhibited by AmF/SnF 2 and SnF 2 solutions, while NaF solutions were less effective and AmF and AmF/NaF showed no significant effect (all solutions: 250 ppm F -). The results of this study suggest that not only the fluoride, but also the respective cation could influence the protective efficacy of the fluoride compound.…”

“…However, in most of these studies, the fluoride compounds were applied with different concentration of F, 24 different pH 10,11,23 or in different formulations (toothpaste, solution, gel or varnish), 19 which makes the interpretation of the results regarding to the impact of the respective cations difficult. Moreover, in some in vitro experiments, the fluoride agents were not applied on pellicle-covered samples but on polished surfaces.…”

Effect of sodium, amine and stannous fluoride at the same concentration and different pH on in vitro erosion Abstract OBJECTIVE: This study aimed to compare the effects 0.5% and 1% sodium, amine and stannous fluoride at different pH on enamel erosion in vitro. METHODS: Bovine enamel samples were submitted to a cyclic de-and remineralisation for 3 days. Each day, the samples were exposed for 120 min to pooled human saliva and subsequently treated with one of the fluoride solutions for 3 min: amine fluoride (AmF, 0.5% and 1% F(-)), sodium fluoride (NaF, 0.5% and 1% F(-)), each at pH 3.9 and 7.0, and stannous fluoride (SnF(2), 0.5% and 1% F(-)), at pH: 3.9. Additionally, two groups were treated with fluoride-free placebo solutions (pH: 3.9 and 7.0) and one group served as control (no fluoridation).Ten specimens each group were inserted in a so-called artificial mouth and eroded six times daily with hydrochloric acid (pH 2.6) for 90 s each intermitted by exposure to artificial saliva (1h). After 3 days, enamel loss was analyzed profilometrically and evaluated statistically by ANOVA. RESULTS: Only the acidic 0.5% and 1% SnF(2) and 1% AmF solutions were able to reduce erosive enamel loss significantly, while all other solutions and placebos did not differ significantly from the control. Between the acidic SnF(2) and the 1% AmF solutions no significant differences could be detected. CONCLUSION: At the same concentrations, acidic SnF(2) and AmF may be more effective than NaF to protect enamel against erosion.

“…The efficacy of TiF 4 to reduce carious demineralisation suggested that it might be also an effective agent in preventing erosive dental loss. In several recent in vitro 3,[11][12][13] and few in situ studies 14,15 it was shown that TiF 4 reduced dental erosion significantly and was more effective than sodium, amine or stannous fluoride.…”

OBJECTIVE: This study aimed to analyse and compare the protective effect of buffered (pH 3.5) and native (pH 1.2) TiF(4) in comparison to NaF solutions of same pH on dentin erosion. DESIGN: Bovine samples were pretreated with 1.50% TiF(4) or 2.02% NaF (both 0.48M F) solutions, each with a pH of 1.2 and 3.5. The control group received no fluoride pretreatment. Ten samples in each group were eroded with HCl (pH 2.6) for 10x60s. Erosion was analysed by determination of calcium release into the acid. Additionally, the surface and the elemental surface composition were examined by scanning electron microscopy (two samples in each group) and X-ray energy-dispersive spectroscopy in fluoridated but not eroded samples (six samples in each group). Cumulative calcium release (nmol/mm(2)) was statistically analysed by repeated measures ANOVA and one-way ANOVA at t=10min. RESULTS: TiF(4) and NaF at pH 1.2 decreased calcium release significantly, while TiF(4) and NaF at pH 3.5 were not effective. Samples treated with TiF(4) at pH 1.2 showed a significant increase of Ti, while NaF pretreatment increased F concentration significantly. TiF(4) at pH 1.2 led to the formation of globular precipitates occluding dentinal tubules, which could not be observed on samples treated with TiF(4) at pH 3.5. NaF at pH 1.2 but not at pH 3.5 induced the formation of surface precipitates covering dentinal tubules. CONCLUSION: Dentin erosion can be significantly reduced by TiF(4) and NaF at pH 1.2, but not at pH 3.5.1 TiF 4 and NaF at pH 1.2 but not at pH 3.5 are able to reduce dentin erosion Objective: This study aimed to analyse and compare the protective effect of buffered (pH 3.5) and native (pH 1.2) TiF 4 in comparison to NaF solutions of same pH on dentin erosion.Design: Bovine samples were pretreated with 1.50% TiF 4 or 2.02% NaF (both 0.48 M F) solutions, each with a pH of 1.2 and 3.5.
