Fluoride profiles of enamel following topical application of neutral and acidulated NaF solution using x-ray photoelectron spectroscopy (ESCA)--an in vitro study.
An in vitro analysis of fluoride in the surface enamel using x-ray photo-electron spectroscopy carried out on sound untreated teeth, sound teeth treated with neutral NaF and acidulated NaF and teeth with artificial caries treated with NaF and acidulated NaF revealed Ca/F ratio at surface and 360 degrees A as 0.140:1 and 0.140:1; 0.636:1 and 0.192:1; 1.112:1 and 0.908:1. 1.2:1 and 1.289:1; 2.11:1 and 1.87:1 respectively.
