title: [The effect of various concentrations of hydrochloric acid solutions on the enamel permeability for 45Ca in experimental fluorosis].
abstract: In 96 months-old dogs with light fluorosis the effect of 10% HCl solution and the mixture of 36% HCl solution with concentrated HCl (1:2) on 45Ca incorporation into the superficial and deep enamel layers, and its penetration into the dental hard tissues. The increase in HCl concentration was directly related to enamel 45Ca incorporation and the depth of its penetration in fluorosis-afflicted teeth. Under effect of 12% HCl solution 45Ca penetrated across the whole enamel reaching the dentin. Further increases in HCl concentration is nonexpedient in bleaching the fluorosis-afflicted enamel.
