  Valorization of Human and Cattle Dental Waste into Functional Composite Biomaterials: A Detailed Comparative Analysis

  By Subhasis Nath, Sourav Debnath, Soumya Mukherjee, Sujan Krishna Samanta

  Abstract: This study investigates the conversion of human and cattle (goat and cow) teeth into bioactive hydroxyapatite-based composites and presents a detailed comparative evaluation of these biogenic materials with laboratory-synthesised (synthetic) hydroxyapatite (HAp). In this work, hydroxyapatite was extracted from human and bovine teeth through controlled calcination and milling, while synthetic HAp was prepared using a standard wet chemical precipitation route. All materials were subsequently sintered at 900 °C and fabricated …

  Fabrication and Comparative Study of Synthetic and Eggshell Waste Derived Hydroxyapatite-Based Composites for Biomedical Applications

  By Subhasis Nath, Sujan Krishna Samanta, Sourav Debnath, Soumya Mukherjee

  Abstract: Hydroxyapatite is widely used as a bioceramic material in orthopedic and dental field because of its exceptional biocompatibility and bioactivity. Hydroxyapatite (HAp) doped with several mineral ions has been frequently reported to further enhance its bioactive nature. Several studies indicate that biological waste materials can serve as calcium sources for hydroxyapatite synthesis, with eggshells being one such promising source. In the present work, two types of hydroxyapatite were synthesized: pure …
