“…The methods used for measurement of the superficial alterations of dental enamel can be quantitative (superficial microhardness, profilometry) and qualitative (scanning electron microscopy) 14 . Microhardness testing permits the measurement of the degree of softening of the surface, but does not allow the quantification of the height of surface loss.…”

“…The profilometric method uses a depth-sensing instrument, which gives the height of this surface loss. Since the dental enamel can be softened (altering the microhardness) in association with dental wear, a combined study, using microhardness and profilometry would be able to quantify the alterations resulted from erosion and abrasion 6,14 . Taking into account the association between erosion and abrasion and the importance of combined methodologies, the purpose of this study was to assess in situ the surface softening and abrasive wear of eroded bovine enamel with or without the influence of toothbrushing, by using profilometric and microhardness analyses.…”

This study assessed the surface softening and abrasive wear of eroded bovine enamel with or without the influence of toothbrushing. Five volunteers took part in this in situ study of 5 days. They wore acrylic palatal appliances containing 6 bovine enamel blocks divided in two rows with 3 blocks, which corresponded to the studied groups: erosion without toothbrushing (GI) and erosion with toothbrushing (GII). The blocks were subjected to erosion by immersion of the appliances in a cola drink for 10 minutes, 4 times a day. After that, no treatment was performed in one row (GI), whereas the other row was brushed (GII). The appliance was then replaced into the mouth. Enamel alterations were determined using profilometry and microhardness tests. Data were tested using paired Student's t test (p < 0.05). The mean wear values (µm) and percentage of superficial microhardness change (%SMHC) were respectively: GI -2.77 ± 1.21/91.61 ± 3.68 and GII -3.80 ± 0.91/58.77 ± 11.47. There was a significant difference in wear (p = 0.001) and %SMHC (p = 0.001) between the groups. It was concluded that the wear was more pronounced when associated to toothbrushing abrasion. However, toothbrushing promoted less %SMHC due to the removal of the altered superficial enamel layer. DESCRIPTORS: Tooth erosion; Tooth abrasion; Beverages. RESUMO:Este estudo avaliou o amolecimento superficial e o desgaste do esmalte bovino erodido com ou sem influência da escovação. Cinco voluntários fizeram parte deste estudo in situ de 5 dias. Eles usaram aparelhos palatinos de acrílico contendo 6 blocos de esmalte bovino divididos em 2 fileiras com 3 blocos, cada fileira correspondeu a um grupo em estudo: erosão sem escovação dentária (GI) e erosão seguida de escovação dentária (GII). Os blocos foram submetidos à erosão por imersão do aparelho em uma bebida à base de cola por 10 minutos, 4 vezes ao dia. Depois disso, nenhum tratamento foi realizado em uma fileira (GI), enquanto a outra fileira foi escovada (GII). Em seguida, o aparelho foi recolocado na boca. Alterações do esmalte foram determinadas por teste de perfilometria e microdureza. Os dados foram analisados usando-se teste t de Student (p < 0,05). O valor médio de desgaste (µm) e da porcentagem de perda de microdureza superficial (%PDS) foi respectivamente: GI -2,77 ± 1,21/91,61 ± 3,68 e GII -3,80 ± 0,91/58,77 ± 11,47. Houve uma diferença estatisticamente significante no desgaste (p = 0,001) e na %PDS (p = 0,001) entre grupos. Conclui-se que o desgaste foi mais pronunciado quando associado à abrasão pela escovação. Entretanto, a escovação promoveu menor %PDS, devido à remoção da camada de esmalte superficial alterada.

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...

“…O entendimento do papel dos aspectos físico-químicos relacionados ao caráter erosivo de bebidas ácidas contribui para fundamentar estratégias que visam minimizar a formação e a progressão de lesões de erosão 17 . Vários estudos mencionam as bebidas alcoólicas como agentes que possuem baixo pH baixo [18][19][20][21] . No presente estudo, o pH médio de 2,34 da Smirnoff Ice ® foi significativamente menor do que qualquer que seja o sabor da Talante ® , apresentando, portanto, um pH ácido passível de desmineralizar o esmalte, caso seja consumido diariamente e em excesso.…”

ResumoIntrodução: A erosão dental é definida como um processo patológico que leva à perda de substância dentária por processos químicos. Atualmente, os fatores de risco para a ocorrência dessa lesão têm sido pesquisados com maior interesse, já que sua incidência aumenta, devido às mudanças nos hábitos alimentares, desordens gastrointestinais e descontrole alimentar psicológico. AbstractIntroduction: Dental erosion is defined as a pathological process that leads to the loss of dental substance by chemical processes. Currently, the risk factors for the occurrence of this lesion have been investigated with greater interest, since its incidence increases due to changes in eating habits, gastrointestinal disorders and psychological eating disorder. Objective: To evaluate the pH of four types of alcoholic beverages (Smirnoff Ice ™ , Talante ™ coconut flavor, Talante ™ cinnamon flavor, Talante ™ mint flavor) at two temperatures (25 ° C and 5 º C), in the view of erosive potential. Material and methods: There were eight copies of each drink in temperatures determined with the aid of a pHmeter. Results: All samples of drinks evaluated presented pH less than 5.0. The pH of Smirnoff Ice ™ is significantly lower than whatever the flavor of Talante ™ . The Smirnoff Ice ™ had an average pH of 2.34, significantly less than other drinks. As for the temperature the results show that it doesn't change the pH of the Talante ™ beverage independent of flavor. Conclusion: However, there is evidence that the temperature alters significantly the pH of the drink Smirnoff Ice ™ . If frequently consumed, the beverages evaluated can contribute to the development of dental erosion.
