X-ray study and microhardness data of some dental enamel species.


X-ray analysis and microhardness of dental enamel of some human and animal species were investigated. Human enamel is composed mainly of hydroxyapatite and fluorapatite together with traces of delta calcium metaphosphate. Prominant apatite phases with a small amount of basic calcium carbonate are also present in the enamel of dog canine teeth. Calcite forms… (More)
