Nitrates of cerium and samarium deposit on human enamel independently of a salivary pellicle.

Objectives: The aim of this study was to analyze the precipitation of Cerium(III)nitrate hexahydrate [Ce(NO)] or Samarium(III)nitrate hexahydrate [Sm(NO)] solutions on human enamel with and without a salivary pellicle. Investigated parameters were At%Ce and At%Sm measured using energy dispersive x-ray spectroscopy (EDX) after test solution (two concentrations) application.

Materials And Methods: Precipitation of Ce(NO) and Sm(NO) solutions was examined on human enamel with and without a salivary pellicle.
