Undecalcified human dentin was prepared for electron microscopy by conventional chemical fixation with alcoholic dehydration and by freeze-substitution with cryodehydration. Comparisons are reported concerning effects of different preparation methods. Morphology remained unaltered in the pre-dentin and mineralized matrices. The technique comparison permitted inferences regarding hydration states and relative amounts of protein in different areas of the odontoblast cell.
