        Hydroxyapatite production and characterization from four pufferfish species teeth

        Servet Ahmet Doğdu,Cemal Turan,Tolga Depci,Ersin Bahçeci,Kemal Sangün,Deniz Ayas 한양대학교 청정에너지연구소 2024 Journal of Ceramic Processing Research Vol.25 No.1

        The pufferfishes are invasive alien fish species in the Mediterranean Sea with a powerful toxin in its body called tetrodotoxin. It has no economic value and is very abundant all over the world’s marine waters. Calcium phosphate bioceramic materialsespecially hydroxyapatite are commonly applied as implant resources because of their close resemblance in structure withnatural bone. In this study, natural hydroxyapatite was obtained from the teeth of four pufferfish, the obtained products werecharacterised and their potential uses in the biomedical industry were revealed. Pufferfish teeth were extracted from the fish,thoroughly rinsed using deionized water, measured, and subsequently placed within a furnace set at a temperature of 105 °C. Once dehydrated, the teeth were finely pulverized using a planetary ball mill. This powdered material was then subjected tovarious analyses, including elemental composition assessment, TTX analysis, and SEM-EDX examinations. Ca/P atomic ratiovalues of Lagocephalus suezensis, L. guentheri, Sphoeroides pachygaster and Torguigener favimaculasus teeth were obtainedas 1.58, 1.64, 1.67 and 1.47, respectively. The analysis findings suggest that pufferfish teeth could serve as a promising naturalalternative source for biomedical and various other industries in need of natural hydroxyapatite. This hydroxyapatite can beutilized for creating fillers, implants, bone powder, and prostheses with applications in biomedicine and various industries. However, it should not be forgotten that the necessary tests must be carried out before any human use is made available.
