| Aims: The objectives of this study to compare the tensile bond strength (TBS) of self-adhesive Flowable composite with conventional fissure sealants. Materials and Methods : an experimental study was carried out using forty non-carious upper first premolars that were collected of orthodontic extracted teeth. The crowns separated from the roots and the buccal surface were cleaned and polished to obtain a clean enamel surface. The samples were randomly divided into 4 main groups according to the types of resin material (n:10 for each group). Group I: testing TBS for Vertise Flow, Group II: testing TBS for Prevent, Group III: testing TBS for Angie, Group IV: testing TBS for Conseal. A translucent plastic tube was fixed after acid etching application on enamel surface for 15 seconds followed by water rinsed and air dryness, the tube filled incrementally with flowable resin and fissure sealant then ready small post screws with twisted orthodontic wire gauge 0.012 inch which placed inside the tube until the serrations of the screws were embedded in the last increment and light-cured. The Samples were stored in the distilled water at room temperature for 24 hours. Tensile bond strength was measured using a universal testing machine (Electronic Elastic Strength Tester GT-C04-2, GESTER, CHINA).The values were statistically analyzed using one way ANOVA and Duncan tests. Results : A significant difference in the tensile bond strength were observed among all groups (p<0.05). Vertise Flow showed higher tensile bond strength value than fissure sealants followed by Prevent , Angie and Conseal. Conclusions: The tensile bond strength of Vertise Flow better than the fissure sealant due to the presence bond (Optibond) with etchant properties. | ||
