Abstract:
Polymers with negative charge groups, such as carboxylic or phosphatic groups, were frequently used to induce or promote the apatite deposition. However, chitosan with potentially chelated calcium ions, were ignored. Inspired by layer by layer technology, chitosan hydrogel without any surface modification process was used as framework to mineralize bone-like apatite. XRD and IR results shown that in situ synthesis bone-like apatite, similar to apatite in rib of rabbit, was carbonate ions partially substituted apatite and preferred growth orientation in direction of their c-axis.

Abstract:
Large bone defect still represent a major problem in orthopedics. A tissue engineering approach has been proposed where osteogenic cells, bioceramic scaffolds and growth factors can play in a role to the bone repair. Bone consist a mineral phase such as carbonate apatite and an organic phase such as collagen. Synthetic carbonate apatite ceramics are considered as promising alloplastic materials for bone substitute. Chitin is the organic matrix of the hard parts of exoskeleton of insect, crustacean and present in a small amounts in mushrooms. It is an insoluble, similar to cellulose and compose

Abstract Background: Calcium phosphate cements (CPC) is a promising materials for bone defect repair. Nanosized apatite or calcium orthophosphate has a better bioactivity than coarser crystals. Chitosan is produced commercially from chitin that is the structural element in the exoskeleton of crustaceans such as crabs and shrimp. The mixing of nanosized apatite and chitosan may provide the consistency cement, improving mechanical properties of the set bone cement. Objective: Develop nanosized apatite powder with chitosan for bone composite cement. Materials and method: Nanosized apatite was syn

Abstract:
This paper describes the apatite deposition of chitosan-silicate porous hybrids derived from chitosan andγ-glycidoxypropyltrimethoxysilane (GPTMS) in alkaline phosphate solution. The preparation of porous hybrids with needle-like apatite on their surfaces is described. Following apatite deposition the porous hybrids maintained high porosity. The enzymatic degradation rate was low even after 6 months and the porous hybrids were very flexible and cut easily using surgical scissors.

Abstract:
In this work, we report the physico-chemical properties and antibacterial activity of apatite/chitosan composite cements. The biocomposite was prepared by reaction between dihydrated dicalcium phosphate and calcium hydroxide in the presence of chitosan. The characterization of cement was carried out by Infrared Spectroscopy, X-ray diffraction, Transmission Electron Microscopy and X-ray Scanner with computational image processing. The results show that the setting of the paste is due to the formation of a hydrated tri-calcium phosphate that evolves into a hard calcium-apatite. In the presence o

A bioactive chitosan-siloxane nano-hybrid material was newly developed and evaluated for the potential application as a bone graft material. The chitosan which can be dissolved in organic solvent was synthesized by the reaction with phtalic anhydride (Ph-Chitosan) and it was then reacted with 3-isocyanatopropyl triethoxysilane (Si-Chitosan) in dimethylformamide. Following this, the Si-Chitosan was hydrolyzed and condensed to yield a hybrid sol-gel material (Si-O-Chitosan).

In this work, experiments to produce a series of nanocomposites based on natural chitosan and nano-clay (MMT) were conducted. Commercially available montmorillonite (MMT) was used as a nanofiller. CS-MMT nanocomposites were prepared using the casting method. Thin nanocomposite foils were neutralized in NaOH solution, then the nanocomposite foils were soaked in simulated body fluid (SBF). Kinetics of crystallization of the apatite structure was observed using PIXE, FTIR-ATR and SEM/EDS techniques.

Abstract:
Missing a permanent tooth is a miserable condition faced by a common man. A tooth decay, periodontitis, mechanical trauma, or any systemic complications lead to such a complication. These bone defects when left untreated lead to severe resorption of the alveolar bone. A proper dental filling with an appropriate bone substitute material could prevent such resorption and paves a way for subsequent implant placement. Dental implants are considered as the prime option by dentists to replace a single tooth or prevent bone resorption. A variety of bone substitutes are available differ in origin, con
