Enamel mottling in a high strontium area of the U.S.A. 1977

M E Curzon, and P C Spector

As part of an epidemiologic study conducted in seven towns in Wisconsin, U.S.A., enamel mottling, opacities, and pigmentations were assessed in 1, 313 12- to 14-year-old schoolchildren. Enamel mottling was found to increase in prevalence and severity as strontium concentrations in communal drinking water increased. This trend held for lifelong residents only, and could not be demonstrated among children who immigrated to the towns after 1 year of life. No relationship of enamel mottling and water fluoride concentrations was found.
