The Effects of Charcoal Toothpaste on Microhardness and Surface Roughness of Nanofilled, Micro hybrid Resin Composite and Resin Modified Glass Ionomer

Abstract

This study evaluated the effects of charcoal toothpaste on the microhardness and surface roughness of nanofilled, micro hybrid resin composite and resin modified glass ionomer. A total of 120 samples (40 samples per each material). Group A: forty samples were fabricated from Z350 XT (nanofilled) resin composite samples. Group B: forty samples were fabricated a from Z250 (micro filled) resin composite. Group C: forty samples were fabricated from Fuji II. The
