The aim of this study was to compared the penetration scores and microleakage levels of flowable resin in comparison to resin-based pit and fissure sealant. A total 120 extracted premolars were used and classified with group I (resin-based pit and fissure sealant), group II (flowable resin), group III (bonding agent + flowable resin), IV (fissurotomy + bonding agent + flowable resin) depending on the materials and the application methods. The penetration scores of the group treated with flowable resin following fissurotomy were similar to those of the group treated with resin-based sealant, but higher compared to those of the other groups treated with flowable resin without fissurotomy or bonding agent. The group treated with flowable resin following fissurotomy also exhibited the lowest microleakage levels. The group treated with resin-based sealant and the one treated with a bonding agent prior to the application of flowable resin showed similar microleakage levels. In conclusion, flowable resin may be applied as a pit and fissure sealant, and its application along with fissurotomy could increase the penetration scores.
