羟基磷灰石及其复合材料作为一种生物陶瓷在生物医学领域有着广泛的应用。本研究用于检查新合成的Eppawala羟基磷灰石复合材料品种作为牙科填充材料的化学和结构的适用性，通过比较和对比它们与人类牙齿以及市售的玻璃离子水门汀（GIC），用于牙科应用。采用市售甲基丙烯酸羟乙酯单体增强固相烧结和溶胶-凝胶法合成羟基磷灰石陶瓷制备复合材料，并比较了它们的物理、化学性能。结果表明，合成产物与人牙相似，但具有较高的热稳定性、良好的结晶性和多孔性。最后，研究得出结论，新合成的复合材料可以直接用作人类牙齿的替代品，同时具有彼此不同的性能。
Hydroxyapatite and its composites have applied in several biomedical applications as a bioceramic. This research used to examine chemical and structural suitability of newly synthesized Eppawala hydroxyapatite composite varieties as dental filling material, by comparing and contrasting them with human tooth as well as commercially available glass ionomer cement (GIC), used in dentistry applications. Commercially available 2-hydroxyethyl methacrylate monomer used to reinforce solid state sintered and sol gel synthesized hydroxyapatite ceramic to prepare its composites and their physical, chemical properties were compared. Results show there is a close similarity between synthesized products and human tooth while credenting high thermal stability, good crystalline, and porous properties than the commercial product. Finally, study concluded newly synthesized composites can be applied directly as a substitution for human tooth while having different properties from each other.
