Abstract

Milk protein has been considered as one of the influenced factors in bone mineral crystallization. Bone mineral is mainly formed by carbonate apatite in which the crystallization process depends on the two main processes, nucleation and crystal growth. This study showed the formation of carbonate apatite by using precipitation method and observed the influence of casein, milk protein, in carbonate apatite nucleation through synthesis and crystal growth through immersion in SBF.  The result showed that carbonate apatite type B was formed by using precipitation method with chicken eggshells as calcium precursor. The addition of casein concentration could promote the apatite nucleation and crystal growth with low casein concentration ( ≤ 7.5 g.l-1) while high casein concentration addition plays role as an inhibitor.

Abstract

Deproteinated human bone with hydrazine indicated that percentage of bone mass mineral increased with individual age in the range of child to adult, and then slowly decreased with ageing. Type of bone and sex also influenced the proportional of mineral in bone. Several information was obtained from infrared spectroscopy measurements. Calcium phosphate in bone mineral was a mixture of amorphous calcium phosphates and apatite crystals that rich of carbonates. Most crystals were carbonate apatite type B, with additional small amount of type A and AB. The splitting factor of υ4 phosphate bands indicated that crystalline degree was regulated by age, increases in the range of child to adult, then decrease up to a certain value (0.16) and finally almost constant. It is predicted that apatite crystals that was formed with less calcium phosphate will accompanied by the insertion of crystallization water in order to maintain the constancy of bone volume.

Abstract

The need for biomaterials tends to increase especially in the field of medicine caused by cases of increasing bone damage. The biomaterial that is being developed for bone implants is hydroxyapatite (HAp). The high value of imports of bone-replacement biomaterials in Indonesia is conidered as a thoughtful problem because of the high price, therefore the development of biomaterials used as a substitute for bone derived from natural materials. In this study, HAp in the form of an injectable bone substitute (IBS) was syntehsized. IBS is a bone-substitute material in the form of a suspension. IBS can be applied by injection to reach deeper areas of bone defects and be able to adjust the shape of bone or tooth defects properly. HAp was synthesized in this study with assistance of microwave irradiation. Mangrove snail shell was used as calcium sources. Furthermore, this study indicated that HAp synthesized from mangrove snail shell had a high potency to be developed as IBS.
