– Images formed in the electron microprobe by the current induced in the sample by absorbed electrons illustrated the prism structure and mineral distribution in the enamel of rat incisors. Close to the dentino‐enamel junction a 2 micron wide zone of high electron density was found, bordered on the peripheral side by a 2–3 micron wide zone of low density. Chemical concentration profiles indicated that the content of calcium and phosphorus in this zone was lower than in the underlying dentin.
