This document discusses obtaining bioceramics from shark teeth for potential use in bone tissue engineering. Shark teeth were characterized using SEM, TEM, and micro-CT scans to analyze their enameloid and dentine composition. The teeth then underwent ball milling, pyrolysis at 950°C, and sieving to produce biological apatite granules with isolated fluorapatite nanocrystals. Preliminary biocompatibility tests of the granules showed optimal cell attachment and proliferation over 21 days, demonstrating their potential for bone tissue engineering applications.
