Electron probe microanalysis was applied to study quantitatively and semi quantitatively the elemental concentrations and distributions that occur in predentine during the dentine mineralization of rat incisor. Apex regions of the continuously growing incisors were rapidly dissected and cryofixed in liquid nitrogen-cooled propane. Ultrathin cryosections were prepared from the dentine tissue. On the average in the extracellular predentine element concentrations of calcium and phosphorus were about 0.5% (w/w) and 0.5-1% (w/w), respectively; so the calcium content in the extracellular predentine is higher while the phosphorus content is much lower than in the odontoblast area. Due to the high content of glycosaminoglycans in the extracellular matrix the concentration of sulfur in the predentine was more than 1% (w/w); the potassium content was found in the range of 0.6-0.8% (w/w) which is quite high for an extracellular area and the concentrations of sodium and chlorine were higher than 2% (w/w). Elemental mapping analysis was carried out to demonstrate the distribution of some important elements at the predentine/dentine border during mineralization.
