The National Institute of Dental and Craniofacial Research defined the incident as the presence of at least ?one carious lesion on a primary tooth in a child under the age of 6 years.?
?The greater proportion of caries experience in the U.S. among 2 to 5 year olds has clearly shifted towards more restored dental surfaces for all 20 primary teeth as well as just for the upper anterior incisors,? Dr. Bruce Dye, dental epidemiology officer at the Centers for Disease Control and Prevention National Center for Health Statistics, said. ?Observed increase in the prevalence of restored primary teeth suggests a decade?s long trend of increase[d] treatment of caries in preschool children.?
?Untreated decay is now on a downward trend,? he continued at a dental conference featuring 260 dentists, academicians, dental personnel, industry representatives, researchers and students. ?Treated decay is on an upward trend. Most of what we?re seeing is based on treated disease.?
