Multi-method analysis of calcium localization in the secretory ameloblast.
X-ray micro-analysis and electron energy loss analysis were used to confirm cytochemical localization by potassium pyro-antimonate of calcium in secretory ameloblasts. Neither intercellular calcium concentration between ameloblasts nor over-all calcium levels of the enamel organ were lowered during a period of inhibition of enamel mineralization by injected fluoride. Calcium concentrations in mitochondria and secretory granules were reduced.
