Twenty-seven percent of children and adolescents aged 5-19 years had at least one dental sealant. Nearly 38% of non-Hispanic black adults had not lost a permanent tooth compared with 51% for non-Hispanic white and 52% for Mexican-American persons. Almost 23% of adults aged 65 and over were edentulous.
