Historically, D(-)-Tartaric acid was first isolated from wine sediments, where it naturally occurs as potassium hydrogen tartrate or cream of tartar. Today, it is predominantly extracted from grape pomace, a byproduct of winemaking, through processes involving precipitation, filtration, and purificatio...
For the removal capacity of teeth tartarevaluation, 30 extracted uniradicular premolars were used, divided in three groups:positive control (NaOCl at 1% + EDTA at 17%), negative control(distilled water) and experimental (POW). Afterwards, the samples were observed under electronic microscopy with...

A.C. impedance measurements help to clarify the underlying chemical mechanisms of material removal. These findings indicate that the Ta sites of TaN are oxidized to Ta 2O 5 by O 2 and H 2O 2 in the solution, followed by structural weakening of the oxide film due to the formation of Ta...
