“…LMR is less sensitive to minute changes in mineral content than TMR, because of the use of thicker specimens as compared with TMR. Using LMR, erosion progression in both enamel and dentin has also been assessed [91][92][93] [69][70][71]. In these studies, the method has shown to be suitable to allow for distinction of different preventive treatment modalities resulting in different mineral loss.…”

Various assessment techniques have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by erosive challenges. In this chapter, the most frequently adopted techniques for analyzing the erosively altered dental hard tissues are reviewed, such as profilometry, measuring microscope techniques, microradiography, scanning electron microscopy, atom force microscopy, nano-and microhardness tests and iodide permeability test. Moreover, methods for chemical analysis of minerals dissolved from dental hard tissue are discussed. It becomes evident that the complex nature of erosive mineral loss and dissolution might not be comprehended by a single technique, but needs application of different approaches for full understanding.

“…Therefore, determination of dental enamel dissolution by assessing the amount of calcium or phosphate dissolved from the apatite crystals of dental hard tissue could also be regarded as a possible tool for assessing dental erosions. Hence, some authors had applied calcium determina-tion in erosive, acidic solutions after prolonged contact (range 2 min to 24 h) of the solutions with dental hard tissue using calcium sensitive electrodes, atomic adsorption spectrophotometer or the highly sensitive method of inductively coupled plasma mass spectrometry [68][69][70][71][72] Calcium-sensitive electrodes often need a specific pH of the environment to work precisely. Additionally, cal-cium complexes formed with certain acids (e.g.…”

“…10 Several previous studies used calcium and phosphate analysis as indirect technique for dissolution analysis of TiF 4 -treated samples. 6,8,12 The protective effect of TiF 4 is attributed to the acid-resistant surface coating formed by the fluoride-metal complex, which might lead to a mechanical protection of the surface. 14 Furthermore, the application of TiF 4 might lead to an increase in the enamel fluoride content.…”

“…[1][2][3] Recently, research into dental erosion focused on the antierosive potential of titanium tetrafluoride (TiF 4 ), which is suggested to be more effective in inhibition of enamel erosion or carious demineralisation than sodium, stannous or amine fluoride. [4][5][6][7] Hove et al 5 reported that TiF 4 (0.5 M F) reduced enamel erosion almost completely (88%), while SnF 2 and NaF treatment resulted in only 50% or 25% protection, respectively. Schlüter et al 4 investigated the influence of 1.64 % TiF 4 and 2.2% NaF (both pH: 1.2) in a cyclic deand remineralization protocol over 5 days.…”

OBJECTIVE: This in vitro study aimed to analyse the protective effect of differently concentrated titanium (TiF(4)), zirconium (ZrF(4)) and hafnium (HfF(4)) tetrafluoride on enamel erosion. METHODS: Polished enamel surfaces of 36 bovine crowns were covered with tape leaving 4 enamel windows each 3mm in diameter exposed. The crowns were randomly assigned to six groups (each n=6) and pretreated with 4% TiF(4), 10% TiF(4), 4% ZrF(4), 10% ZrF(4), 4% HfF(4) or 10% HfF(4) for 4 min (first window), 10 min (second window) or 15 min (third window). The fourth window of each crown was not pretreated and served as control. Erosion was performed stepwise with 1% HCl (pH 2) in five consecutive intervals of each 15 s (total 75 s). Enamel dissolution was quantified by colorimetric determination of phosphate release into the acid. For each tooth, cumulative phosphate loss of enamel pretreated with one of the tetrafluoride compounds was calculated as percentage of the respective control and statistically analysed using two-way ANOVA. RESULTS: Enamel erosion was significantly reduced by TiF(4), ZrF(4) and HfF(4) application. Cumulative phosphate loss (mean % of control, 75s erosion) after 4-15 min application was significantly lower for 4% ZrF(4) (7-11%), 10% ZrF(4) (2-6%), 4% HfF(4) (11-9%) and 10% HfF(4) (12-16%) compared to 4% TiF(4) (42-27%) and 10% TiF(4) (54-33%). Only for 4% and 10% TiF(4), phosphate loss decreased with increasing duration of application, but also increased with increasing acid intervals. CONCLUSION: TiF(4), ZrF(4) and HfF(4) might protect enamel against short-time erosion, but protection was more enhanced by ZrF(4) and HfF(4) compared to TiF(4) application overtime. 1 Protection of short-time enamel erosion by different tetrafluoride compounds AbstractObjective: This in-vitro-study aimed to analyse the protective effect of differently concentrated titanium (TiF 4 ), zirconium (ZrF 4 ) and hafnium (HfF 4 ) tetrafluoride on enamel erosion.Methods: Polished enamel surfaces of 36 bovine crowns were covered with tape leaving 4 enamel windows each 3 mm in diameter exposed.
