ABSTRACT
Crab's shells of Portunus pelagicus species were used as raw materials for synthesis of hydroxyapatite were used for protection against demineralization of teeth. Calcination was conducted to crab's shells of Portunus pelagicus at temperature of 1000°C for 5 hours. The results of calcination was reacted with (NH4)2HPO4, then dried at 110°C for 5 hours. Sintering was conducted to results of precipitated dried with temperature variations 400-1000°C for a hour each variation of temperature then characterized by X-ray diffractometer and FTIR in order to obtain the optimum formation temperature of hydroxyapatite is 800°C. The hydroxyapatite is then tested its effectiveness in protection against tooth demineralization using acetate buffer pH 5.0 with 1 M acetic acid concentration with the addition of hydroxyapatite and time variation of immersion. The results showed that the rate of tooth demineralization in acetate buffer decreased significantly with the provision of hydroxyapatite into a solution where the addition of the magnitude of hydroxyapatite is greater decrease in the rate of tooth demineralization.

fig11: Relationship between teeth immersion time versus PO43− ion concentration in a solution where teeth soaked or immersed.

Mentions: Figure 11 shows the relationship between the soaking time of teeth versus the increase of the ion PO43− levels in solution where the tooth was soaked as well; it appears that with the increasing addition of Ca10(PO4)6(OH)2 into the acetate buffer equals to the rate of demineralization decrease. It is can be altered by the amount of PO43− ions in solutions; however the addition of Ca10(PO4)6(OH)2 ions showed lower amount of PO43− ions compared to solutions without the addition of Ca10(PO4)6(OH)2. This proves that the Ca10(PO4)6(OH)2 were synthesized from the crab shell effective for protection against tooth demineralization.
