Abstract

Objective: To evaluate the shear bond strength (SBS) and the adhesive remnant index (ARI) of different traditional orthodontic adhesive systems and newly developed pre-coated adhesive systems.
Methods: A total of 50 human maxillary premolars were bonded with Clarity advanced ceramic brackets using APC™ Flash-Free, APC™ PLUS, Transbond™ XT Light Cure, Opal® Bond™MV and, Blugloo™ adhesives. All samples underwent thermo-cycling. The SBS was determined using a testometric machine. A stereomicroscope was used to evaluate the adhesive remnant on debonded enamel surface. Differences among the adhesives were tested for statistical significance.
Results: Blugloo™ group had the highest SBS (22.69 ± 9.14 MPa). However, there was no significant difference in mean SBS among the groups (p<0.05). The Flash-free adhesive group had a significantly lower ARI score than Opal® Bond™MV and, Blugloo™ groups (p<0.001).
Conclusion: All experimental groups provided clinical bond strength higher than required. The flash-free adhesive group resulted in lower adhesive remnant, this saves time for the clinician.
