Characterization of processed tooth hydroxyapatite for potential biomedical implant applications
Summary
Hydroxyapatite derived from human teeth is a viable, simple-to-produce biomaterial. This natural hydroxyapatite (HA) is comparable to synthetic HA and suitable for further biocompatibility testing as a graft material.
Area of Science:
- Biomaterials Science
- Dental Research
- Materials Engineering
Background:
- Hydroxyapatite (HA) is a key component of human hard tissues.
- Investigating natural sources of HA for biomaterial applications is crucial.
- Human teeth offer a readily available source of HA.
Purpose of the Study:
- To characterize hydroxyapatite derived from human teeth.
- To compare natural tooth-derived HA with synthetic HA.
- To assess the potential of tooth-derived HA as a biomaterial graft.
Main Methods:
- Characterization using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDXS).
- Analysis via wet chemical methods, Ion Chromatographic Peak (ICP) method, atomic absorption, X-ray diffraction (XRD), and Infra-Red (IR) spectroscopy.
- HA was isolated from both dentine and enamel of human teeth.
Main Results:
- Natural HA derived from human teeth exhibited comparable properties to synthetic HA.
- The production process for tooth-derived HA was found to be relatively simple.
- No significant differences were observed between HA from dentine and enamel.
Conclusions:
- Human tooth-derived HA is a promising biomaterial.
- Its simple production and similarity to synthetic HA support its potential use.
- Further biocompatibility studies are recommended before use in animal and human subjects as a graft material.
