Study of the Arrangement of Crystallites in y-Irradiated Human Enamel by Electron Paramagnetic Resonance

Abstract

The arrangement of tooth enamel microcrystals has been studied on CO 3 3- bound electrons by electron paramagnetic resonance. It was found that noncarious human maxillary central incisors have a greater degree of alignment of tooth enamel microcrystals than the carious ones. The outermost surface layer of enamel showed a greater crystallite degree of alignment than other parts.
