Incorporation of copper into chitosan scaffolds promotes bone regeneration in rat calvarial defects.
The objective of this study was to investigate the effects of a copper loaded chitosan scaffold on bone regeneration in critical-sized calvarial defects in rats. Chitosan scaffolds and copper-chitosan scaffolds were fabricated and characterized by scanning electron microscopy (SEM). Chitosan and copper-chitosan scaffolds were implanted into 5 mm diameter critical-sized calvarial defects in Fish...
متن کاملComparative study of porous hydroxyapatite/chitosan and whitlockite/chitosan scaffolds for bone regeneration in calvarial defects
Hydroxyapatite (HAP; Ca10(PO4)6(OH)2) and whitlockite (WH; Ca18Mg2(HPO4)2(PO4)12) are widely utilized in bone repair because they are the main components of hard tissues such as bones and teeth. In this paper, we synthesized HAP and WH hollow microspheres by using creatine phosphate disodium salt as an organic phosphorus source in aqueous solution through microwave-assisted hydrothermal method....
متن کاملEnhancement of bone formation in rat calvarial bone defects using low-level laser therapy.
OBJECTIVE To evaluate the effect of low-level laser therapy (LLLT), using a GaAlAs diode laser device, on bone healing and growth in rat calvarial bone defects. STUDY DESIGN An animal trial of 4 weeks' duration was conducted using a randomized blind, placebo-controlled design. Standardized round osseous defects of 2.7 mm diameter were made in each parietal bone of 20 rats (n=40 defects). The ...
متن کاملreconstructing calvarial bone lesions using phbv scaffolds and cord blood mesenchymal stem cells in rat
background: for tissue engineering of bone, anatomical and operational reconstructions of damaged tissue seem to be vital. this is done via reconstruction of bone and appropriate biological joint with bone tissues of damaged areas. in this study the condition of biodegradable bed nano fiber phbv and ussc cells were used to accelerate bone repair of damaged area. methods: hollow nanofabrication ...
متن کاملSimvastatin and biphasic calcium phosphate affects bone formation in critical-sized rat calvarial defects.
PURPOSE To investigate the effects of locally applied simvastatin plus biphasic calcium phosphate (BoneCeramic(r)) or collagen sponge on bone formation in critical-sized bone defects. METHODS Thirty defects of 5mm in diameter were created bilaterally with a trephine bur in the calvariae of fifteen Wistar rats. The defects were divided into five groups: group 1 - control, no treatment; group 2...
