    Clinical Effect of Dental Adhesive on Marginal Integrity in Class I And Class II Resin-Composite Restorations.
    Folia Med (Plovdiv) 2015 Jul-Dec;57(3-4):250-6
    Background: Dental adhesives are believed to influence marginal adaptation and marginal discoloration when used under posterior resin-based composite restorations. Studies on the latest adhesive systems reveal that the group of the three-step etch-and-rinse adhesive (3-E&RA) and the one-step self-etch adhesive (1-SEA) have entirely different bonding mechanisms, as well as different bond strength and resistance to chemical, thermal and mechanical factors.
