Nano SiO2 and MgO particles were incorporated into β-tricalcium phosphate (β-TCP) scaffolds to improve the mechanical and biological properties. The porous cylindrical β-TCP scaffolds doped with 0.5 wt % SiO2, 1.0 wt % MgO, 0.5 wt % SiO2 + 1.0 wt % MgO were fabricated via selective laser sintering respectively and undoped β-TCP scaffold was also prepared as control. The phase composition and me...

Four hundred isolates obtained from soil samples collected from forest, river basin, agricultural fields and rhizosphere of plantation crops of North Bengal were screened for phosphate solubilizing activity on Pikovskaya’s agar medium. Among the screened isolates, ninety showed phosphate solubilizing activity. Out of these, ten isolates belonging to Aspergillus niger, A. melleus and A. clavatus...

The purpose of this study was to investigate how aragonite (calcium carbonate) whiskers influenced the strengthening and carbonating of alpha-tricalcium phosphate (alpha-TCP) based calcium phosphate cement. Aragonite whiskers of 0.95 microm width with an aspect ratio of 6.6 were prepared. The cement powder, alpha-TCP containing 0-50 mass% aragonite whisker, was mixed with 0.6 mol/L NaH2PO4 solu...

In this study, the effects of sodium lauryl sulfate and various amino acids (DL-aspartic acid, dodecanedioic suberic acid) on formation calcium-deficient hydroxyapatite via hydrolysis α-tricalcium phosphate (α-TCP) were investigated; moreover, a combined effect these additives ethylene glycol as synthesis medium was also estimated. The reaction performed in solutions containing different concen...

Tricalcium phosphate (TCP) synthetized by high temperature solid state reaction at 1400°C and three derived calcium cements (CPCs) prepared liquid to powder (L/P) ratios of 0.33, 0.44 0.55 ml/g, respectively, were physicochemically characterized. Calcium deficient hydroxyapatite crystals identified scanning electron microscopy on CPC, differences in crystal sizes observed different L/P ratios. ...

This study was to evaluate the acid-buffering capacity and antibacterial properties of orthodontic adhesives containing bioactive glasses (BAGs) (45S5, 45S5F, S53P4), Hydroxyapatite, beta-tricalcium phosphate, Canasite. Fillers comprising 15 wt% glasses, HAp, β-TCP, Canasite incorporated with 55 silanated glass were added a mixture UDMA/TEGDMA. Acid-buffering tested by exposing disc-shaped samp...

We have succeeded in improving the material properties of a chelate-setting calcium-phosphate cement (CPC), which is composed of hydroxyapatite (HAp) the surface of which has been modified with inositol hexaphosphate (IP6) by adding α-tricalcium phosphate (α-TCP) powder. In order to create a novel chelate-setting CPC with sufficient bioresorbability, gelatin particles were added into the IP6-HA...

Because calcium phosphate (Ca-P) ceramics have been used as bone substitutes, it is necessary to investigate what effects the ceramics have on osteoblast maturation. We prepared three types of Ca-P ceramics with different Ca-P ratios, i.e. hydroxyapatite (HA), beta-tricalcium phosphate (β-TCP), and biphasic calcium phosphate (BCP) ceramics with dense-smooth and porous structures. Comprehensive ...

The in vitro effect of platelet-rich plasma (PRP) on cell loading, proliferation, and osteogenic differentiation of human mesenchymal stem cells (MSC) is assessed on distinct resorbable and synthetic calcium *Author to whom correspondence should be addressed.
