“…17 Analysis of calcium ion release from enamel tissues after demineralization cycles was used as a well-accepted method for the assessment of erosion progression. 25,30 In contrast to the reflection analysis, no statistically significant differences were found in calcium dissolution among all groups at all applied erosion times [ Fig. 7(b)] except enamel samples remineralized in human saliva (group 2) and mineral solution (group 4) after a total of 8 min of erosion (Table 3).…”

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.

“…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.…”

“…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.

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 demineralization occurs in a centripetal manner 6 , beginning with the interprismatic area and following through the central region of the prism. The increase of the demineralized area generates a higher surface roughness 7 and decreases the microhardness of dental tissue 8 . In consequence of the alterations caused on surface characteristics, the enamel surface becomes more susceptible to the action of mechanical forces 9 .…”

Dental erosion is a multifactorial pathology that leads to dental substrate loss caused by its exposure to acids of non-bacterial origin. The process begins with a superficial demineralization of enamel, which, when continuously exposed to erosive solutions, can even lead to dentin exposure, causing aesthetic/functional problems to patients, besides increasing the chances of dentin hypersensitivity. Fluoride ResumoA erosão dental é uma patologia multifatorial que leva a uma perda de substrato dental causada pela sua exposição a ácidos de origem não-bacteriana. O processo se inicia com uma desmineralização superficial do esmalte, que, quando da continua exposição a soluções erosivas, pode levar a exposição do esmalte, causando problemas estéticos/funcionais aos pacientes, além de aumentar a chance de hipersensibilidade dentinária. Os produtos fluoretados, quando aplicados sobre a superfície dental, formam uma barreira física de proteção, que também pode agir como reservatório de íons F. Entretanto, frente a recorrentes desafios erosivos, esta proteção tem efetividade limitada. A literatura recente já demonstrou a capacidade de compostos contendo cátions metálicos polivalentes associados a fluoretos, incluindo o tetrafluoreto de titânio (TiF 4 ), para formar camadas mais ácido-resistentes. A capacidade do íon titânio de se ligar simultaneamente aos íons F e ao tecido dental permite a formação de uma barreira de difusão na superfície dental, conhecida como glaze, que a protege contra desmineralização ácida. Entretanto, ainda é necessário estabelecer um protocolo clínico ideal envolvendo a definição de fatores capazes de determinar o sucesso do tratamento, como concentração, pH, veículo e forma/tempo de aplicação, além da frequência para reaplicação. A presente revisão crítica tem como objetivo proporcionar uma breve visão geral dos mecanismos de ação do TiF 4 e discutir os fatores que podem melhorar sua capacidade protetora contra a erosão dental.Palavras-chave: Erosão Dentária. Flúor. Titânio.
