Introduction. The objective of this investigation is to pinpoint the influence of the salivary pH on the hardness of the dental enamel. Method. The study was realized using recently extracted 6 non-carious wisdom teeth, that were immersed in solutions of different pH (between 2.5 and 6.5) for 3 minutes, solutions that would simulate the pH of the oral cavity in patients with a potential condition of gastroesophageal reflux disease. The hardness of the enamel was tested using the Vickers method. Results show that t...

Background: Knowing the real values of enamel mechanical properties, both at macro and microscopic scale, it is highly significant to select those compatible dental materials, in terms of behavior, as close as possible to the natural structures. The aim of the study was to assess human enamel microhardness both in normal enamel samples (control) and in demineralized enamel samples, using the Vickers microhardness test, and also to analyze the effect of indentation loads (100gf, 200gf, 300gf) applied for 10s on the...
