Divalent cation and phosphorus content of normal and strontium-laden rat maxillary incisors was determined by electron microprobe analysis. A high positive correlation of magnesium and strontium distributions was found. Where strontium was elevated, calcium was only slightly depressed. Phosphorus appeared to be distributed randomly.
