Özet

Tooth enamel, the hardest tissue in the human body, is composed mainly of calcium phosphate mineral crystals which has a chemical formula Ca10(PO4)6(OH)2 (HA, hydroxyapatite). Understanding the various properties of human teeth and dental materials is the basis for the development of restorative materials. The production of nano hydroxyapatite powder derived from human teeth was studied in this paper. The nano hydroxyapatite powder (≈ 52 nm) was produced by calcination without compaction. The dried and calcined powder were characterized for phase composition using X-ray diffractrometry, Fourier transform infrared spectroscopy and Energy-dispersive Xray spectroscopy techniques. The average crystallite size of HA powder was calculated by Debye Scherrer’s formula. Field emission scanning electron microscopy and Transmission electron microscopy studies were performed for further investigation of particle size and powder morphology.
