ABSTRACT
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 andMethods:
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 andConclusion:
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
