Chemical analyses of hydroxyapatite formation on SAM surfaces modified with COOH, NH2, CH3, and OH functions
Hydroxyapatite formation SAM surfaces Surface plasmon resonance
2010/11/29
Hydroxyapatite formation was examined at the surface of self-assembled monolayers (SAMs) modified with four functional groups, -COOH, -NH2, -CH3, and -OH. For COOH-SAM and NH2-SAM, scanning electron s...
Analysis of Chemical Interaction of 4-MET with Hydroxyapatite Using XPS
Adhesion 4-MET XPS
2009/9/15
Each dental adhesive contains a specific functional monomer that determines its actual adhesive performance to tooth tissue. 4-methacryloxyethyl trimellitic acid (4-MET) is well-known as one of the fu...
Role of Acidic Amino Acid for Regulating Hydroxyapatite Crystal Growth
Hydroxyapatite Crystal growth Acidic amino acid
2009/9/14
Non-collagenous proteins in hard tissue matrix are thought to play a pivotal role in regulating the crystal growth of hydroxyapatite (HAp). As most non-collagenous proteins are acidic proteins contain...
Effects of Sintering Temperature Over 1,300°C on the Physical and Compositional Properties of Porous Hydroxyapatite Foam
Porous hydroxyapatite Scaffold Synthetic bone substitute
2009/9/14
Porous hydroxyapatite (HAP) foam permits three-dimensional (3D) structure with fully interconnecting pores as well as excellent tissue response and good osteoconductivity. It is therefore thought to b...
Hydroxyapatite Film Coating by Thermally Induced Liquid-phase Deposition Method for Titanium Implants
Hydroxyapatite Liquid-phase deposition method Titanium implant
2009/9/14
Thermally induced liquid-phase deposition method was employed to produce a thin hydroxyapatite (HA) film on a titanium substrate in a metastable calcium phosphate solution. Titanium foil of 100×10×0.0...
Development of Cell-hybrid Artificial Bone: Effect of Osteogenic Differentiation of Bone Marrow Stromal Stem Cells on Bone Formation with Newly Developed Interconnected Porous Calcium Hydroxyapatite
Interconnected porous calcium hydroxyapatite Bone regeneration Cell-hybrid artificial bone
2009/9/14
The purpose of this study was to evaluate the effect of osteogenic differentiation of bone marrow stromal stem cells (BMSCs) on bone formation in a novel interconnected porous calcium hydroxyapatite (...
Hydroxyapatite coating by electrophoretic deposition at dynamic voltage
Hydroxyapatite coating Electrophoretic deposition Dynamic voltage
2009/9/11
The aim of this study was to evaluate hydroxyapatite (HA) coatings produced by dynamic voltage during electrophoretic deposition (EPD). Dynamic voltages from 0 to 200 V were incrementally applied in t...
Comparison of Osteogenic Potential Between Apatite-Coated Poly(Lactide-Co-Glycolide)/Hydroxyapatite Particulates and Bio-Oss®
Apatite coating Bio-Oss® Bone regeneration
2009/9/11
Previously, we developed a poly(lactide-co-glycolide)/nano-hydroxyapatite (PLGA/HA) composite that overcame the limitations of conventional ceramic bone substitutes. This was achieved by introducing a...
Histopathologic Responses of Dog’s Dental Pulp to Mineral Trioxide Aggregate, Bio Active Glass, Formocresol, Hydroxyapatite
Animal study Bio Active Glass (BAG) Calcification Dental pulp Dentinal bridge
2009/4/2
Introduction: Bio Active Glass (BAG) is often used as a filler material for regeneration of dental bone defects. Mineral trioxide aggregate (MTA) is used as retrofilling agent, repair of root resorp...
Bioactivity Evaluation of Synthetic Nanocrystalline Hydroxyapatite
Bioactivity Evaluation Synthetic Nanocrystalline Hydroxyapatite
2009/4/2
Background: Bone regeneration in the defects around oral implants using substitutes may improve
long-term prognosis of the implant. Hydroxyapatite (HA) is a good candidate for bone substitutes due ...
