The effect of different finishing polishing protocols on stain absorption and color stability of resin composite restorations.

Purpose: To evaluate the degree of stain absorption of resin composite following different finishing and polishing protocols and to evaluate the efficacy of prophylaxis paste with or without addition of carbamide peroxide to remove composite surface stain.

Methods: 50 resin composite blocks were prepared using nano-hybrid composite (Filtek Z250XT) and giomer (Beautifil II LS). Specimens were either polished with a disk or coated with 5th/7th generation bonding or glycerin gel.
