This represents the mean number of questionnaire responses per subject per time period. Subjects received questionnaires every 3 to 4 months before age 4, and every 6 months after age 4. For ages 2-5, the subjects received a maximum of 10 questionnaires, and for ages 5-8, subjects received a maximum of 7 questionnaires.
Fluorosis prevalence is defined as 2 or more teeth in a tooth group with definitive fluorosis using the Fluorosis Risk Index (FRI).
