Abstract

As a part of a series of studies to examine the role of the initiator system in dentin bonding, the effectiveness of a new polymerization initiator system consisting of 2-methyl-1, 3-cyclohexanedione (MCHD) and CuCl2 in dentin bonding was investigated in terms of the effects of dentin conditioners and CuCl2 concentration formulated in MMA/PMMA resins. Curing time and tensile bond strength to bovine dentin were measured using resins composed of MMA containing 0.001-0.03wt% CuCl2 and PMMA powder containing 2wt% MCHD. The dentin surfaces were treated with six conditioners consisting of 10wt% phosphoric acid or citric acid containing 0-3wt% FeCl3 or CuCl2. The bond strengths of about 10MPa obtained under optimal conditions were comparable to those reported for tributylborane-initiated MMA resin which is one of the most effective bonding resins available. Thus, the resin using MCHD/CuCl2 system was concluded to be very effective for dentin bonding, especially when dentin was treated with acidic conditioners containing ferric or copper chloride.
