“…Such an instrument has been used for this purpose by many other workers in laboratory erosion studies. 15,[31][32][33][34] Often tape is applied to the specimen prior to immersion to limit the area of tooth substance The mean is the result of fi ve experimental runs. In the case of those drinks where water was added, the mean is the result of fi ve experimental runs of a 25 ml sample drawn from a dilution of 25 ml drink plus 6.25 ml water.…”

“…When pH is low or acid, there is a higher level of erosion. 20 However, ESen and the water groups had similar pH values (around 7) and showed different enamel loss, which was lower in ESen. This occurrence showed the protective effect of fluoride associated with the citrate potassium in the toothpaste (ESen).…”

Background: The aim of this study was to investigate the effect of arginine and fluoride on the reduction of erosive wear. Methods: Bovine enamel blocks were randomly allocated into four groups (n = 20) and exposed to: ESPR group (8% arginine, 1450 ppm sodium monofluorophosphate, calcium carbonate and titanium dioxide); ESen group (1450 ppm sodium monofluorophosphate, 5% potassium citrate); positive control PC group (1500 ppm sodium monofluorophosphate) and negative control NC group (water). The samples were submitted to six alternating cycles of demineralization-remineralization (cola, 10 minutes; artificial saliva, 1 hour, respectively). Before and between cyclic demineralization and remineralization, blocks were treated with slurries of the respective toothpastes or water (1 minute). Erosive tissue loss was analysed by microhardness and profilometry. Data were analysed by ANOVA and Tukey tests for individual comparisons among the groups (p < 0.05). Results: In microhardness, the ESPR (217.46 AE 55.45) group was significantly better than the other treatment groups (PC = 302.76 AE 96.10; ESen = 315.56 AE 74.56; p < 0.001). The ESPR group showed a similar loss to NC group (NC = 210.8 AE 49.98; p = 0.991). The mean erosion depth (+/-SE, lm) was detected between NC (14.37 AE 1.72) and dentifrices tested (ESPR (4.11 AE 1.34), ESen group (7.64 AE 1.61) and PC (8.20 AE 2.19) (p = 0.000). Conclusions: From the results of the present study, the effectiveness of Sensitive Pro Relief in the prevention of erosive surface loss seems to be attributed to the possible effect of the arginine associated with fluoride.

“…A adição dos íons cálcio ao gel seria capaz de promover a saturação do agente clareador e diminuir a perda de minerais do esmalte durante o tratamento, aumentando, consequentemente, a resistência à desmineralização 20 . Além disso, Ca adicionado a soluções ácidas é capaz de diminuir a perda mineral do esmalte em até 50% 21,22 .…”

IntroduçãoAo longo das últimas décadas, há uma busca crescente por melhores condições estéticas e tratamentos clareadores, que se mostram eficazes, seguros e com bons resultados 1 . O clareamento dental é a técnica menos invasiva e mais conservadora, porém pode apresentar algumas desvantagens, como sensibilidade, ulcerações nos tecidos moles e, por vezes, toxicidade 2 . Portanto, o profissional deve ter experiência com o mecanismo de ação e conhecimento da segurança biológica dos agentes clareadores, para poder indicá-los de forma correta e orientar seus pacientes sobre o tratamento. Existem várias técni-cas de clareamento, como o clareamento caseiro com moldeira individual, o clareamento em consultório e o clareamento combinado, que associa as técnicas de consultório e caseira. As indicações e os tipos de clareamento estão relacionados às alterações de cor, que podem ser causadas por fatores extrínsecos ou intrínsecos 3,4 , e às características do paciente.Entretanto, estudos mostram que o peróxido de hidrogênio é um agente oxidante com alta capacidade de penetração no esmalte e na dentina devido ao seu baixo peso molecular 2 e, dependendo da técnica empregada, da quantidade de sessões, do tempo de exposição e da concentração do agente clareador, pode acarretar efeitos indesejáveis, como a sensibilidade e a alteração da morfologia do esmalte [5][6][7][8][9] . A literatura sugere que o uso indiscriminado dos
