Changing patterns of dental disease in children and the use of dental services.

By 1980, more than 106 million individuals from 8,000 communities nationwide were receiving adjusted fluoridated water. An additional 9.8 million people in 3,000 communities were using water with naturally occurring fluoride levels. A review is provided of the continuing need for, and use of, dental services by children since the first adjustment in a community's water supply 42 years ago.
