Abstract
This landmark study of a pit and fissure sealant found 27.6 percent complete retention and 35.4 percent partial retention on permanent first molars. In the matched pair analysis, carious or restored surfaces made up 31.3 percent of the surfaces in the sealed group and 82.8 percent in the unsealed group.
