Dental sealants are recognized as an effective approach to preventing pit and fissure caries in children. However, the Centers for Disease Control and Prevention reported in 2005 that among children aged 6–19 years, only 32 percent had received dental sealants. The national oral health objectives for dental sealants, as stated in the U.S. Department of Health and Human Services initiative Healthy People 2010, include increasing the proportion of children who have received dental sealants on their molar teeth to 50 percent.
