Quantitative X-ray microanalytical and histochemical patterns of calcium and phosphorus in enamel in human amelogenesis imperfecta

We used scanning electron microscopy (SEM) and quantitative X-ray microanal ysis, with the peak-to-local background ratio method and microcrystal line calcium and phosphrous salts as standards, to establish quantitative patter n of biomineralization (Ca/P ratio) in enamel of incisors and molars from p atients with a clinical and genetical diagnosis of amelogenesis imperfecta. (Al). No significant differences were observed between the Ca/P ratio of A l and normal enamel teeth.
