Aim: To investigate the bond strengths achieved by using a Bleaching Curing Light (BCL) to polymerize orthodontic bonding cement. Material and Methods: 160 anterior bovine teeth were used to form 20 average sized human dental arches, and distributed into 2 groups according to which light curing method used: Group 1: BCL for 40 seconds, or Group 2: LED for 10 seconds. After storage in a controlled environment, Shear Bond Strength (SBS) and Adhesive Remnant Index (ARI) were determined. Results: Group 1 showed significantly lower SBS in the most posterior (first molar) position of the dental arch, (Group 1: 0.7 ± 1.0 MPa, Group 2: 2.9 ± 1.7 MPa, p < 0.01), but significantly higher SBS in the most anterior position (Group 1: 5.1 ± 1.8 MPa, Group 2: 3.8 ± 1.2 MPa, p < 0.02). A high correlation was found between the position of the bracket and debonding values (p < 0.02). Bonding failures in the most posterior arch positions occurred more frequently within Group 1, and lower ARI than Group 2 over corresponding arch locations. Conclusion: Simultaneous full-arch curing of orthodontic bracket cement using a BCL is clinically acceptable in all but the most posterior locations along the dental arch.
