the aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles.this in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-tcp nanoparticles) and two control groups contai...

RF sputtering method was used for deposition 70wt% CeO2/TCP thin film on stainless steel 316L surface. The selection of ceria and tricalcium phosphate is according to the fact importance these materials in biomedical media. produced coating characterized by XRD, FESEM/EDS AFM analysis, result revealed that obtained peaks from XRD refer deposited materials. When substitution Ce done, distorting ...

Calcium phosphate has been widely used in bone regeneration applications. Originalkalsium fosfat merupakan biomaterial yang sering diaplikasikan ke dalam defek tulang dengan tidak memberikan efek toksik pada jaringan sehat.The most commonly calcium are hydroxyapatite and β-tricalcium (β-TCP). β-TCP is one of the bioceramic materials that chemical structure β-Ca3(PO4)2. The use medicine dentistr...

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

In this paper, preparation, bioactivity, and osteoblast cell behavior of cortical bone derived nano-biphasic 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 ele...

Incorporation of trace elements into calcium phosphate structure is of great interest for the development of artificial bone implants. Biphasic calcium phosphate (BCP) composed of hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) have been synthesized in the presence of magnesium (5 M% 20 M%) by gel method under physiological conditions. Crystallization of Mg-BCP in the gel medium mimics t...

Osteomyelitis therapy is a long-term and inconvenient procedure for a patient. Antibiotic-loaded bone cements are both a complementary and alternative treatment option to intravenous antibiotic therapy for the treatment of osteomyelitis. In the current study, the biphasic calcium phosphate cement (CPC), called α -TCP/HAP ( α -tricalcium phosphate/hydroxyapatite) biphasic cement, was prepared as...

The aim of this study was to evaluate the therapeutic efficacy of biomimetic zinc-containing tricalcium phosphate (ZnTCP) produced by hydrothermally converting calcium carbonate exoskeletons from foraminifera, in the treatment of osteoporotic mice. X-Ray powder diffraction showed crystallographic structures matching JCPDS profile for tricalcium phosphate. Mass spectroscopy used to calculate tot...

Long-term results are reported in 23 patients and short-term results in 30 patients presenting with bone tumors treated by curettage or resection followed by implantation of hydroxyapatite (HA) or highly purified beta-tricalcium phosphate (beta-TCP), respectively. Mean follow-up was 97 and 26 months in cases involving HA implantation and beta-TCP implantation, respectively. Radiographs revealed...

Beta-tricalcium phosphate (beta-TCP) combined with recombinant human bone morphogenetic protein-2 (BMP-2) was examined as a substitute for autograft for packing into interbody fusion cages in the canine lumbar spine model. Discectomy and interbody cage fusion were performed at three disc spaces in eight dogs. Examination of microradiographs and histological sections of the lumbar spine at 16 we...
