title: Relationship of strontium in drinking water and surface enamel.
abstract: The Sr content of surface enamel of 233 teeth from nine communities was related to drinking water Sr concentrations. These water concentrations ranged from 0.02 microgram/ml to 33.9 microgram/ml. The relationship between enamel concentrations and water concentrations was linear for water concentrations less than 10 microgram/ml Sr, but leveled off at approximately 300 microgram/gm Sr in the enamel for communities with greater than 10 microgram/ml Sr in drinking water. Binding of Sr to components in the oral environment is proposed as an explanation of this effect.
