“…Finally, to conclude the description of the known CaPO 4 , one should mention that in spite of the well-defined crystallographic data (Table 4) and, therefore, the welldefined shapes of the single crystals, various types of CaPO 4 can be prepared with the controllable sizes from nano-to macro-scale (up to centimeter size) and the diverse shapes including zero-(particles), one-(rods, fibers, wires and whiskers), two-(sheets, disks, plates, belts, ribbons and flakes) and three-dimensional morphologies (Sadat-Shojai et al 2013;Lin et al 2014). The latter might be of versatile morphologies and shapes (Fig.…”

“…Calcium phosphate (CaP), especially hydroxyapatite, is one of the most popular materials widely used in biomedical, biomaterial and bioengineering applications because of its biocompatibility, osteoconductivity, non-inflammable, bioactive, biodegradable and non-toxicity properties. Moreover, the methods and conditions of CaP preparation such as sol-gel, microwave, and hydrothermal methods are reported to have an effect on the sizes, morphologies and phases of CaP [3][4][5].…”

Abstract. Dentinal hypersensitivity (DH) is one of the most human's problems caused by the erosion of enamel. There are many methods and materials to solve this problem. Calcium phosphate is an excellent alternative for curing this symptom because of its osteoconductivity, and biocompatibility properties. The low-cost and low-toxicity calcium phosphate nanogel was fabricated by using emulsion method and characterized by using TEM, EDX, and DLS techniques. The results showed that P123 (poly (ethylene oxide)19-block-Poly (propylene oxide)69-block-poly (ethylene oxide)19) has played a major role as template and gel formation, SDS was used as a surfactant to form water-in-oil emulsion nanodroplets with circle-like shape. Moreover, the ability of synthesised organogel to occlude the exposed dentine tubules was tested on the model of human's dentine slices. The results showed that calcium phosphate composite organogel can be efficiently occluded on dentine slice, characterized by SEM technique, after 1 day.

“…On the other hand, Miller et al reported that DCPA is obtained at 567 K as a product of DCPD dehydration [38]. Lin et al demonstrated that it is necessary to generate a basic environment with hydroxides or air in order to prevent HA decomposition into calcium phosphates [39]. HA decomposition at low temperature is possible due to the excess of OH-ions from Zr(OH) 4 and HA.…”

Ceramics and bioceramics, such as hydroxyapatite and zirconium, are used in bone tissue engineering. Hydroxyapatite has chemical properties similar to bone while zirconium offers suitable mechanical properties. The aim of this article is to evaluate the ability to support cell growth and osteoblastic mineralization of hydroxyapatite-zirconium obtained by a new system based on different low temperatures, such as 873 K (HZ600), 923 K (HZ650) and 973 K (HZ700). Hydroxyapatite-zirconia obtained by this new system was examined in terms of thermogravimetric features and x-ray diffractograms. Furthermore, the ability for supporting osteoblast growth and mineralization were analyzed. By x-ray diffraction analysis, we clearly demonstrated that no high-temperature processing was required. Moreover, it is possible to form tetragonal-zirconium at 923 K. Proliferation assays showed that osteoblast growth was not influenced by any of the composite evaluated. Regarding the osteogenic marker Col1, a 2-fold increase in expression was observed for HZ650 compared to HZ600 and HZ700. Interestingly, osteoblasts grown on HZ650 showed globular accretions covered with collagen bundles and calcium-rich extracellular matrix whereas HZ600 and HZ700 showed no phosphate or calcium deposits. This study demonstrated that at 923 K it is possible to generate stable tetragonal-zirconium and the resulting HZ650 composite is able to promote a suitable osteoblast mineralization process.
