Abstract

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