An experimental cavity disinfectant (ACC) that is intended to be used for various direct and indirect restorations was prepared by adding an antibacterial monomer 12-methacryloyloxydodecylpyridinum bromide (MDPB) at 5% into 80% ethanol. The antibacterial effectiveness of ACC and its influences on the bonding abilities of resin cements were investigated. To examine the antibacterial activity of unpolymerized MDPB, the minimum inhibitory and bactericidal concentrations (MIC and MBC) were determined for Streptococcus mutans, Lactobacillus casei, Actinomyces naeslundii, Parvimonas micra, Enterococcus faecalis, Fusobacterium nucleatum, and Porphyromonas gingivalis. Antibacterial activities of ACC and the commercial cavity disinfectant containing 2% chlorhexidine and ethanol (CPS) were evaluated by agar disk diffusion tests through 7 bacterial species and by MIC and MBC measurement for S. mutans. The effects of ACC and CPS to kill bacteria in dentinal tubules were compared with an S. mutans–infected dentin model. Shear bond strength tests were used to examine the influences of ACC on the dentin-bonding abilities of a self-adhesive resin cement and a dual-cure resin cement used with a primer. Unpolymerized MDPB showed strong antibacterial activity against 7 oral bacteria. ACC produced inhibition zones against all bacterial species similar to CPS. For ACC and CPS, the MIC value for S. mutans was identical, and the MBC was similar with only a 1-step dilution difference (1:2). Treatment of infected dentin with ACC resulted in significantly greater bactericidal effects than CPS ( P < 0.05, analysis of variance and Tukey’s honest significant difference test). ACC showed no negative influences on the bonding abilities to dentin for both resin cements, while CPS reduced the bond strength of the self-adhesive resin cement ( P < 0.05). This study clarified that the experimental cavity disinfectant containing 5% MDPB is more effective in vitro than the commercially available chlorhexidine solution to eradicate bacteria in dentin, without causing any adverse influences on the bonding abilities of resinous luting cements.

OBJECTIVE: To compare the bond strength of two dual-cure resin cements to Ni-Cr alloy test specimens (TS), with and without surface treatment. METHODS: RelyX ARC and Panavia Fluoro Cements were tested. Eighty nickel alloy TS were cast, measuring 10mmx7mmx2.5mm, forming a total of 40 pairs. Four groups of TS were obtained.Twenty pairs were treated by airborne abrasion with 50µm aluminum oxide particles and 20did not undergo treatment.The TS were cleaned usingultrasound. The parts were cemented according to manufacturers' instructions. A shear bond strength test was performed until bond failure occurred. RESULTS: Analysis of variance (ANOVA) showed there was a statistical difference (p>0.05) between thegroups. Visual analysis of optical microscopy images showed a mixed fracture pattern with adhesive predominance for RelyX ARC, and mixed with cohesive predominance for Panavia F. The sandblasted groups obtained better bonding, with Panavia F attaining higher bond-strength values than RelyX ARC. CONCLUSION: The Ni-Cr alloy/Panavia F on a treated surface behaved better in terms of bonding.
