Chemical-cure resin cement has been widely used for orthodontics. To improve the clinical handling of chemical-cure resin cement, a dual-cure resin cement system composed of methyl methacrylate (MMA), urethane dimethacrylate (UDMA) and light activator was developed. The purpose of this study was to estimate the efficacy of an experimental dual-cure resin cement.A composite bracket was bonded to the teeth with one of eight resin cements: (1) Unifast II (Uni II); (2) Unifast II containing camphor quinone (Uni II-CQ); (3) Transbond XT (TB); (4) Orthomite Superbond (SB); (5) Unifast LC (Uni-LC); (6–8) experimental dual-cure resin cement—Exp1, Exp2 and Exp3, respectively. Shear bond strength (SBS) of all of the bonded brackets was measured after the cementation.The data were statistically divided, the highest cement (Uni-LC), the next group (Exp1, Exp2, Exp3 and SB) and the lowest group (Uni II, Uni II-CQ and TB).The dual-cure resin cement exhibited a bonding efficacy comparable to that of Superbond.
