Table 3: Effect of fluoride release from sealant material on enamel demineralization and wall lesion frequency

Sealant		Mean outer lesion depth (micrometers)		Wall lesion frequency		Reduction in outer lesion depth
Group A (nonfluoridated pit and fissure sealant)		214.44 ± 97.44		0%		3% when compared with fluoride-releasing sealant
Group B (fluoridated pit and fissure sealant)		222.73 ± 80.66		0%
Group C (glass ionomer pit and fissure sealant)		155.99 ± 37.87		0%		27% when compared with conventional nonfluoride-containing seal style="border-bottom:solid 1px #000000;"ant 30% when compared with the fluoride- releasing sealant group
