Diffusion of Strontium from Desensitizing Agents into Human Dentin as Determined by Energy-Dispersive AnalysisCase Western Reserve University, Cleveland, Ohio 44106, USA
Ohio State University, Columbus, Ohio 43210, USA Strontium-containing desensitizing agents were applied to one set of tooth surfaces and were burnished onto another set of diametric surfaces. Concentration of strontium at dentin depth was determined by X-radiation dispersive analysis. Burnishing produced deeper strontium penetration. Fick's Second Law provided an estimate of relative effective time for equal strontium distributions by the two methods.
