Introduction: The purpose of this study was to evaluate the effect of a highly filled light-cured sealant (HFLCS) on the shear bond strength of metal, ceramic and titanium brackets bonded with resin-modified glass ionomer cement (RMGIC).
Materials and Methods: A total of 60 freshly extracted maxillary premolars were randomly divided into six groups (10 in each group). In all groups, the teeth were etched with 37% phosphoric acid for 20 s and RMGIC (Fuji Ortho LC, GC Europe) was used for bracket bonding. Group 1: Titanium brackets were bonded directly to etched enamel surfaces. Group 2: Titanium brackets were bonded to etched enamel surfaces covered with HFLCS (Pro Seal, Reliance Orthodontic Products, Itasca, IL, USA). Group 3: Metal brackets were bonded directly to etched enamel surfaces. Group 4: Metal brackets were bonded to etched enamel surfaces covered with HFLCS. Group 5: Ceramic brackets were bonded directly to etched enamel surfaces. Group 6: Ceramic brackets were bonded to etched enamel surfaces covered with HFLCS. The specimens were tested in shear mode with a universal testing machine. After debonding, the teeth and the brackets were examined under a scanning electron microscope. Univariate analysis of variance (analysis) was performed to test the main effects of bracket type and HFLCS.
Result and Conclusion: The effect of HFLCS on etched enamel surfaces did not affect the bond strength values and bond failure modes of metal, ceramic and Titanium brackets bonded with RMGIC |
