The study looked at various different authors’ opinions on the process of bone mineralization. Its aim was to induce the mineralization of decalcified bones in-vitro. The study used dog, sheep as well as human bones which were subjected to decalcification after a preliminary analysis of their composition of elements using a scanning electron microscope equipped with an X-ray probe. Following this, re-mineralization was attempted by submersion in a replete solution of calcium phosphate and free vaporization of the water in a temperature of 35°C. This resulted in attaining crystals which were not hydrocsyapatite on the bone’s surface. The study indicated that simple chemical phenomena cannot be the main factor causing bone mineralization.
