Enamel surfaces that had been treated with an acid phosphate-fluoride gel were analyzed for phosphorus, calcium, fluorine, and carbon using X-ray photoelectron spectroscopy. This technique revealed a heavy carbon coating on the enamel that overlays a surface composed of a 1:2 ratio of calcium to fluorine. Evidence is presented for a noncaL cium phosphorus species in the surface layer. Removal of successive layers of enamel by argon-ion etching showed a steady decrease in fluorine and a corresponding increase in phosphorus concentrations.
