Abstract
This study seeks to know the effect of fluoride topical application on the shear bond strength between enamel and fissure sealant. On group 1,2,3,4, Teethmate A(unfilled sealant) and on group 5,6,7,8 Ultraseal XT(filled sealant) were used. Group 1 and 5 were not pre-treated with fluoride and group 2 and 6 were pre-treated with 1.23% APF for 4minutes. Group 3 and 7 were pretreated with 2.0% NaF for 4 minutes. and group 4 and 8 were pumiced with abrasive containing fluoride for 10 seconds. Prepared specimens were acid etched for 30 seconds using 35% phosphoric acid, and then sealant was cured to the specimen using a 3mm diameter by 2mm height mold. They went through thermocycling. Its shear bond strength was measured, and then acid etched both groups that were pretreated with fluoride and that were not pretreated with fluoride. Then we examined the surface of the specimen with EM and came up with these results. In groups using unfilled sealant(group 1,2,3.4) there were no significant differences between oops pretreated with fluoride and groups not pretreated with fluoride. In groups using filled sealant(group 5,6,7,8), groups 6 and 7(treated with 1.23% APF 2.0% NaF respectively) showed significantly lower shear bond strength, compared to group 5 (not pretreated with fluoride) and group 8 (pumiced with abrasive containing fluoride) (p<0.05).
