The results had revealed that the maximum values of tensile strength, compression, bending strength, hardness, impact energy and water absorption%, were (57.6828 N/mm2 at 3% wt. CaCO3, 124.0965 N/mm2 at 9% wt. CaCO3, 102.188 N/mm2 at 9% wt. MgO, 88.2 Shore D at 9% wt. CaCO3, 0.27 J at 6%wt. CaCO3 and 0.8432 % at 15%wt.CaO) compared with reference values, i.e.( 37.4742 N/mm2, 100.3563 N/mm2, 34.194 N/mm2, 83 Shore D, 0.36 J and 0.2626%) respectively.展开更多
The bio- inspired strategy of triggered release of Ca^2＋ , Pi, F from prosomal compartments was used to induce rapid formation of FHA for potential dental use ： Calcium and inorganic phosphate salts were separately ...The bio- inspired strategy of triggered release of Ca^2＋ , Pi, F from prosomal compartments was used to induce rapid formation of FHA for potential dental use ： Calcium and inorganic phosphate salts were separately loaded into temperature-sensitive liposome composed of 90% DPPC and 10% DMPC. When heated from the room temperature to 35- 37 ℃ , the entrapped calcium, inorganic phosphate and fl^rin released from the liposome,A mixture of Ca- Pi and F-loaded liposome formed apatite. The mineral was indicated by a rapid drop in suspension PH from 7.4 approximately 6. This was illustrated by applying a liposome suspension warmed human dentin and enamel surface which resulted in deposition of apatite onto the tissue substrates.展开更多
