title: Study of the arrangement of crystallites in gamma-irradiated human enamel by electron paramagnetic resonance.
abstract: The arrangement of tooth enamel microcrystals has been studied on CO3-3 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.
