“…It shows good correlation between different opera-tors [121] [92]. However, enamel thickness changes of less than 0.33 mm could not be detected precisely with this method [122] In table 1, the main advantages and main problems encountered with the described methods are depicted. Moreover, the methods are judged with respect to the requirements, such as their suitability for early erosion or for use with native surfaces.…”

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.

Copyright © 2006 S. Karger AG, Basel Acid attack leads to an irreversible loss of the outermost enamel and dentin layers and to partial demineralization (softening) of the tooth surface. 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]. For simulating intra-oral erosion as closely as possible, it is desirable to assess the erosive effects on native tooth surfaces. Most of the methods described below need polished surfaces for precise assessment of the erosively induced defects or for creating reference surfaces, which means that the natural, often fluoridated surface of the tooth has to be removed. However, it should be considered that in the case of intra-oral erosion the outermost surface layers are also continuously removed by the acid attack, so that a 'polished' surface is Attin 2 cre-ated. When monitoring of erosive surface alterations within a period of time is performed, it could become necessary to fix a specimen in the measuring device i...

“…This also means that V marked areas might not necessarily have the same SOS present in T marked areas. Furthermore, anisotropy in teeth has been reported by several studies as a primary obstacle for the utilisation of diagnostic ultrasound in dentistry (Harput et al 2011;Huysmans and Thijssen 2000;Louwerse et al 2004;Slak et al 2011;Tagtekin et al 2005). …”

“…Tagtekin et al (2005) investigated ultrasound for monitoring occlusal enamel on worn molars in vitro and concluded that ultrasound was a promising tool for that task. Indeed, several studies have compared ultrasound measurements with histology, the gold standard in the field, but with mixed results (Harput et al 2011;Louwerse et al 2004;Slak et al 2011;Tagtekin et al 2005). One factor that may explain the variation between these studies is the assumed SOS in enamel.…”
