Clinicians often do not place pit and fissure sealants immediately after topical fluoride treatment because fluoride treatment might reduce bonding to enamel. The effect of NaF, SnF2, and APF on the in-vitro bond strength of two sealants to enamel was determined. The fluoride treatments and control (artificial saliva) were applied to enamel surfaces for four minutes and rinsed. A filled sealant (FluoroShield) and an unfilled sealant (Concise) were bonded to the etched enamel and debonded in tension using a universal testing machine. NaF increased the bond strength of the unfilled sealant; SnF2 and APF had no significant effect. NaF and APF decreased the bond strength of filled sealant while SnF2 had no significant effect. The bond strength of the filled sealant was higher than or equal to that of the unfilled sealant. Exposure of enamel to NaF, SnF2, or APF prior to placement of unfilled or filled sealants has no effect on in vitro bond strength between the enamel and the sealants.
