OBJECTIVE
To determine changes in surface gloss of different composite materials after laboratory toothbrushing simulation.
METHODS
40 specimens were fabricated for each material (Filtek Supreme XTE, Renamel, Empress Direct, Gradia Direct, Edelweiss, G-aenial, Venus Pearl and Venus Diamond) and
OBJECTIVE
To evaluate if material thickness can influence the L*a*b* coordinates and translucency of different composite shades.
METHODS
Twelve composite disc specimens made of three different resin composite materials (dentin A2, Essentia, GC; body shade A2, Brillant Everglow, Coltene-Whaledent;
