Effects of adhesive systems applied under fissure sealants to microleakage and shear bond strength
Abstract :
OBJECTIVE: The aim of this study was to examine the effect of bonding agents under fissure sealants on bond strength and microleakage. MATERIALS AND METHOD: A total of 210 freshly extracted noncarious human third molar teeth were used (105 teeth for shear bond strength and 105 teeth for microleakage assessment). The teeth were randomly assigned to 14 groups, with 15 teeth in each group. Fissurit FX was applied to the etched enamel in the control groups. In the experimental groups, the self-etch adhesives: Clearfil SE Bond, G Bond, Clearfil DC Bond and the total-etch adhesives: Prelude, Adper Single Bond and Optibond S were applied and light-cured followed by the subsequent application and light-curing of Fissurit FX. Shear bond strength was tested to failure in a universal testing machine with a 1 mm/min crosshead speed. The shear bond strength data was analyzed by using One Way ANOVA and Tukey HSD tests. Microleakage was evaluated by using a dye penetration method after mechanical loading and thermocycling. The microleakage data was analyzed by using the Kruskal-Wallis and Tamhane tests. RESULTS: The microleakage of the Adper Single Bond Plus group was significantly less than that of the control group (p 0.05). However, the shear bond strength value of the Adper Single Bond Plus group was significantly less than that of the control group, again. The shear bond strength value of Clearfil SE Bond was significantly greater than that of the control group (p 0.05). CONCLUSION: Clearfil SE Bond improved the shear bond strength, and Adper Single Bond Plus decreased the microleakage of the fissure sealant. An inverse relationship was found between the microleakage and the shear bond strength performances of Adper Single Bond Plus.
