PURPOSE: To evaluate the surface changes of resin-based composites (RBC) when they were exposed to acidulated phosphate fluoride (APF) agents. MATERIALS AND METHODS: One microfilled (Silux Plus) and four hybrid (Clearfil AP-X, Lite-Fil IIA, Palfique Estelite, Progress) RBCs were separately treated with two APF agents (Fluorident Gel, Floden A). Changes in surface roughness were determined with a surface analyzer, and relief patterns were observed using a scanning electron microscope. RESULTS: Although the surfaces of hybrid RBC materials containing macro-inorganic filler particles were generally found to be rougher than that of the microfilled composite regardless of APF treatment, macro-inorganic fillers in two of the hybrid composites demonstrated noticeable etched patterns generated by an APF solution.

  • Fluoride (ACT® , APF Gel® , Control Rx® , ...)

    Fluoride is used to prevent tooth decay. It is taken up by teeth and helps to strengthen teeth, resist acid, and block the cavity-forming action of bacteria. Fluoride usually is prescribed for children and adults whose h...
