Nano-hydroxyapatite (nano-HAp) is a biomaterial which finding increasing application in dentistry due to its osteogenic properties and biocompatibility. The aim of the present study review clinical applications nano-HAp dentistry. A literature search was performed PubMeD Scopus. In total, 154 articles were retrieved. Following title abstract analysis, 122 excluded. Further 6 excluded through fu...

In the present study, in-situ synthesis of carbon nanotube/hydroxyapatite nano composite powder with stable homogeneous dispersions of carbon nanotubes (CNTs) was carried out using surfactant as dispersing agent. By applying sol-gel method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were investigated. The chemical and phase composition, structure and morpholo...

Hydroxyapatite nanoparticles (nano-HAPs) have been reported to exhibit antitumor effects on various human cancers, but the effects of nano-HAPs on human glioma cells remain unclear. The aim of this study was to explore the inhibitory effect of nano-HAPs on the growth of human glioma U251 and SHG44 cells in vitro and in vivo. Nano-HAPs could inhibit the growth of U251 and SHG44 cells in a dose- ...

OBJECTIVE Dental caries is an infectious disease that can be prevented in several ways. The aim of this study was to compare the efficacy of sodium fluoride mouthrinse and nano- hydroxyapatite (nano-HA) for the remineralization of incipient caries. MATERIALS AND METHODS After obtaining different concentrations of nano-HA (0-2-5-10%), 60 sound premolars fixed in acrylic blocks were coated with...

Large bone defects are challenging to repair and novel implantable materials needed aid in their reconstruction. Research the past years has proven beneficial effect of porosity an implant on osteogenesis vivo. Building this research we report here porous composites based photo-crosslinked poly(trimethylene carbonate) nano-hydroxyapatite. These were prepared by a temperature induced phase separ...
