SEM Analysis of Enamel Abrasion after Air Polishing Treatment with Erythritol, Glycine and Sodium Bicarbonate

摘要: The aim of this in vitro study was to evaluate the enamel surface topography after treatment with three air polishing powders: Glycine (A), erythritol (B), and sodium bicarbonate (C) (Air Flow Soft, Plus Classic powders, EMS Electro Medical Systems S.A., Nyon, Switzerland). Fifteen extracted incisors were randomly divided into groups five teeth each, A, B C, respectively. blocked plaster bases, washed, dried half-covered polytetrafluoroethylene strips before treatment. In way, each half-treated dental element became test control itself. Comparative statistical analysis Rq (geometric average deviations occurring roughness profile) performed. scanning electron microscope (SEM) showed different degrees between groups, decreasing addition, a statistically significant reduction p < 0.05 present group C (Rq mean non-treated 108.17 µm, 95% CI: 97.29–124.01 treated 86.78 80.63–93.70). A decrease post-treatment not observed B. Therefore, it may be concluded that flow powders tested herein can used on reduce due function action therapies.
