[CDC Kids’ Health] Vital Signs: Dental Sealant Use and Untreated Tooth Decay Among U.S. School-Aged Children

In this study, approximately 60% of children aged 6-11 years from low-income families (approximately 6.5 million children), did not have dental sealants. Although sealant prevalence during the last decade increased by 72% among low-income children, these children were still 20% less likely than children from higher-income families to have dental sealants. Children without sealants had almost three times more cavities in permanent first molars compared with children with sealants.
