Methods. Dental caries exams were performed on 5171 children ages 5 months
through 4 years, and a parent or other caregiver was asked to complete a questionnaire
giving information about the child and her or his household. The children
were recruited from Head Start programs; Women, Infants, and Children
(WIC) nutrition programs; health fairs; and day care centers in a representative
sample of Arizona communities with populations of more than 1000 people.
