Purpose: The purpose of this in vitro study was to evaluate the microleakage of 3 one-bottle adhesives with different solvents added under the fissure sealant on intact etched enamel.

Methods: A total of 100 sound mandibular third molars were randomly divided into 5 groups (N=20). Occlusal pits and fissures were sealed with an unfilled fissure sealant (FS) material. Study groups included: (1) phosphoric acid etching + FS (control); (2) acid etching + Adper Single Bond 2 + FS; (3) acid etching + OptiBond Solo Plus + FS; (4) acid etching + One-Step Plus + FS; and (5) no pretreatment (FS alone). After aging and thermocycling, specimens were placed in 0.5% fuchsin, sectioned, and evaluated by digital microscope. Data were analyzed with Kruskal-Wallis and Mann-Whitney tests at a significance of P<.05.

Results: Group 5 (FS alone) showed the greatest microleakage, which was significantly different from the other groups (P<.05). Group 4 showed the lowest microleakage, followed by groups 3 and 2. No significant differences existed among groups 1 to 4 (P>.05).

Conclusions: Conventional acid etching alone or with a one-bottle adhesive that contained different solvents of acetone, ethanol, or ethanol/water combination yielded similar sealing results in sealant therapy.
