Curing depth of pit and fi ssure sealants with use of light emitting diode (LED) at different distances

A Blue phase C5 LED light (Ivoclar Vivadent) was utilized for the present study. Sealant utilized was Helioseal F (Ivoclar Vivadent). Particular number 27 of the American Dental Affiliation (ADA) was taken after: a 20 mm x 20 mm, 2 mm thick glass was utilized. On it, a specimen making mold was put (with it, 4 mm distance across what's more, 6 mm long examples were gotten). All together to save separation amongst pits and crevice sealant surface and light source, a 5 mm long and 6 mm width glass tube was utilized. The tube was of 10 mm length and 6 mm width. Polymerization profundity was measured in 90 pits and crevices examples. Examples were collected into three gatherings (30 examples per bunch).
