in this paper, preparation, bioactivity, and osteoblast cell behavior of cortical bone derived nanobiphasic calcium phosphate (nano-bcp) are presented. the calcined bovine bone samples with the addition of di-ammonium hydrogen phosphate were heated at 700°c for 100 min, and thus nano-bcp with the composition of 63/37 hydroxyapatite (ha)/β-tricalcium phosphate (β-tcp) was produced. scanning elec...

The study is about evaluating the effects of three remineralising agents i.e. Casein Phosphopeptide - Amorphous Calcium Phosphate [CPP-ACP], Sodium fluoride varnish and Tricalcium phosphate (TCP) on dentin. objective this to see which have a better effect In study, thirty freshly extracted human central incisors are selected with exposed labial surfaces each tooth divided into four quadrants tr...

background: some types of implants used for orbital implantation have side effects and complications. in this study we have evaluated beta-tricalcium phosphate (ß-tcp: chronos) granules as an orbital implant.   methods: eighteen rabbits randomly allocated to four groups. right eye enucleation performed in groups i to iii followed by filling with autologous bone particles (n=5), a mixture of aut...

native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...

Adipose-derived stem cells (ADSCs) are ideal seed cells for use in bone tissue engineering and they have many advantages over other stem cells. In this study, two kinds of calcium phosphate/collagen composite scaffolds were prepared and their effects on the proliferation and osteogenic differentiation of ADSCs were investigated. The hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) composite sca...

Abstract Introduction: Achievement of new drugs with minimal side effects is a important goal in the cancer treatment due to irreversible side effects of conventional drugs. Tricalcium phosphates as natural bone components have unique characteristics including excellent biocompatibility, high biosorption and superior bioactivity. This research aimed at investigating the inhibitory effect of tr...

This study reports the enhanced mechanical resistance of composite bioceramics hydroxyapatite (HAP) and tricalcium phosphate (β-TCP) used as bone substitute. HAP/β-TCP mixture was prepared by wet mixing powders characterized. Effects powder manufacturing sintering temperature on densification, microstructure properties were studied. The rupture strength ( σ r ) calculated using Brazilian test. ...

This study aimed to investigate the free calcium released from different brands of toothpaste after incorporation with a beta-tricalcium phosphate (?-TCP)/amorphous (ACP) mixed powder and ?-TCP alone. Four were used for experiment: Nano-Bio Activation Toothpaste, Colgate Total Advanced Whitening BORONIA Herbal Whitening, BioMin F. The investigated ACP powders prepared by two-step sintering meth...

In this study, L-lactide was used to modify the tricalcium phosphate (β-TCP) and tetracalcium phosphate (TTCP) surface which can form functionalized poly(l-lactic acid) (PLLA)-grafted β-TCP (g-β-TCP) and PLLA-grafted TTCP (g-TTCP) particles. The g-β-TCP and g-TTCP obtained were incorporated into a PEG-PCL-PEG (PECE) matrix to prepare injectable thermosensitive hydrogel composites. The morpholog...
