Aim: This study aims to quantify and evaluate Salivary IgA levels in Carious Individuals pre post-application of Fluoridated, Nano-hydroxyapatite CPP-ACP toothpaste.Materials Methodology: In aggregate, 90 patients were selected randomly from the outpatient department. DMFT DMFS indices performed prior patient selection. After completion analysis, 30 having a moderate score selected. A saliva sa...

Objective(s): Design and construction of biocompatible and biodegradable scaffolds are among the main goals of tissue engineering. Recently, use of nano-hydroxyapatite as a bioactive bioceramic agent with high similarity to the mineral phase of the human bone tissue, in combination with biodegradable polymers and implant coatings has attracted the attention of researchers in the field of biomat...

Chronic osteomyelitis is a prolonged persistent disease accompanied by bone destruction and sequestrum formation, it is very difficult to treat. Antibiotic loaded polymethyl methacrylate (PMMA) has been used in clinical. However, when PMMA was implanted in the body, the deficiencies is that it is non-biodegradable and a second operation is needed. Here, we synthesize a novel levofloxacin loaded...

Three-dimensional (3D) silk fibroin scaffolds were modified with one of the major bone tissue derivatives (nano-hydroxyapatite) and/or a collagen derivative (gelatin). Adhesion and proliferation of mouse embryonic fibroblasts (MEF) within the scaffold were increased after modification with either nano-hydroxyapatite or gelatin. However, a significant increase in MEF adhesion and proliferation w...

Porous silicon (PS) substrates, with different pore sizes and morphology, have been used to crystallize hydroxyapatite (HA) nano-fibers by an easy and economical procedure using a co-precipitation method at room temperature. In situ formation of HA nanoparticles, within the meso- and macroporous silicon structure, resulted in the formation of nanometer-sized hydroxyapatite crystals on/within th...

objective(s):   the production of nano-hydroxyapatite by two encapsulated bacterial strains was the goal of current research.  materials and methods:   serratia marcscens atcc 14756 and pseudomonas aeruginosa ptcc 1570 were used by two methods including encapsulated form in 2% (w/v) alginate sodium powder and inoculated form (10%) in nutrient broth medium containing alginate sodium blank beads....

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...

Magnesium has been recently recognized as a biodegradation metal for bone substitute application. In the present work, porous magnesium-zinc scaffolds were prepared by powder metallurgical process and nano hydroxyapatite (HAP) coating on the Mg-3Zn (wt.%) scaffold was prepared by pulse electrodeposition and alkali treatment processes to improve the corrosion resistance of scaffold. The results ...
