Sealant was applied to all teeth with the same conventional technique. In the first group, fissure sealant was applied without bonding agent, in the second group, it was used with total etch bonding agent (single/3M), and finally in the third group it was applied with self-etch bonding agent (G-bond/GC). Microleakage assessment was done by a stereomicroscope.
