Such a concept of a constitution, assumed, already at its adoption, that the citizens remain passive in the process of implementation and subsequent realisation of its ideas. Additionally, saturating the constitution with ideological elements gave it the nature of a political declaration. In contras...

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...

Background It is still a challenge for physicians and researchers to identify the patients at risk, to make an early diagnosis and to do a correct monitoring for the progress of periodontitis. According to the research literature, Immunoglobulin A (IgA) is the first line of oral mucosal defense against bacterial invasion, including periodontitis. Also, 8-Hidroxy-2-Deoxy Guanosine (8-OHdG) is a result of DNA modification suffered by the attack of free radicals resulted from the oxidative stress processes in periodo...
