“…Recently, the colorimetric Arsenazo III method was described allowing precise determination in acidic solution of small volumes of 10 tJl in a spectropho-tometer [8] [19] [8,17]. However, this method also could not be applied in all kind of acids with the same precision.…”

“…In enamel, acid attacks due to immersion of specimens in erosive solutions lead to a surface etching pattern with exposition of enamel prisms to an extent depending on the severity of the erosive challenge. SEM investigations were also applied for evaluating the efficacy of salivary acquired pellicle to protect underlying enamel surface from acidic dissolution [16][17][18] [14][15][16] or to demonstrate superficially deposited precipitates resulting from mineral dissolution with dif-ferently acting acids [19] [17]. In dentin, acid treatments may result in opening of the dentin tubules which could be graded according to its degree [20] [18].…”

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.

In enamel, the thickness of the softened layer is estimated to be 2-5 tJm [1,2] [1, 2]. The softened eroded tooth surface is highly susceptible to abrasive wear, and mechanical impacts such as toothbrushing can easily remove the superficially demineralized dental hard tissue [3][4][5] [3][4][5].

“…The dynamics of these diffusion processes will differ between dental caries and erosion, but nevertheless will influence disease pathogenesis. This is demonstrated by the protection of the enamel surface to acid exposure when covered by a salivaderived pellicle (Meurman & Frank, 1991;Hannig & Balz, 1999). However, the protective effect of the pellicle may vary in relation to the efficacy of oral hygiene and the nature of dentifrice used (Kuroiwa et al, 1993).…”
