Porous yttria-stabilized zirconia (YSZ) has been regarded as a potential candidate for bone substitute due to its high mechanical strength. However, porous YSZ is biologically inert to bone tissue. It is therefore necessary to introduce bioactive coatings onto the walls of the porous structures to enhance its bioactivity. In this study, porous YSZ scaffolds were prepared using a replication tec...
Scaffolds have an important role in cartilage tissue engineering. Poly(hydroxybutyrate‑co‑hydroxyvalerate) (PHBV) has been demonstrated to have potential as a scaffold for the three dimensional construction of engineered cartilage tissue. However, the poor hydrophilicity and mechanical strength associated with PHBV affects its clinical applications as a scaffold in cartilage tissue engineering....
Bioactive glass has found extensive application as an orthopedic and dental graft material and most recently also as a tissue engineering scaffold. Here we report an initial investigation of the in vitro antibacterial properties of AgBG, a novel bioactive glass composition doped with Ag(2)O. The bacteriostatic and bactericidal properties of this new material and of two other bioactive glass com...
Bioactive glasses were discovered in 1969 and provided for the first time an alternative to nearly inert implant materials. Bioglass formed a rapid, strong, and stable bond with host tissues. This article examines the frontiers of research crossed to achieve clinical use of bioactive glasses and glass-ceramics. In the 1980s, it was discovered that bioactive glasses could be used in particulate ...
PURPOSE To evaluate the effects of copaiba oil on jaw defects repair in Wistar rats treated with bioglass or adipose tissue. METHODS A jaw defect was randomly created in forty-two rats and filled with bioglass or adipose tissue. The two groups (Gbio and Gcell) were subdivided in three subgroups with seven animals each according to gavage administration: control (distillated water), oil (copai...
OBJECTIVE This study aimed to evaluate in vitro the effect of formulations containing Biosilicate to treat enamel and dentin bovine samples exposed to dental bleaching agents. MATERIALS AND METHODS On enamel and dentin bleached with commercial gels containing 16% carbamide peroxide (CP) (14 days/4 h) or 35% hydrogen peroxide (single session/45 min), desensitizing dentifrices (Sensodyne(®); ex...
Galway, Ireland Bioglass filled poly(D, L lactide) Composites with Osteogenic and Angiogenic Potential for Enhanced Bone Tissue Regeneration Lutz-Christian Gerhardt, Tahera Ansari, Melek Erol, Simon Gabe, Iman S. Roqan, Aldo R. Boccaccini Corresponding Author: [email protected] 1 Department of Materials, Imperial College London, UK, 2 Department of Surgical Research, Northwick Park Inst...
conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...
The effect of TiO2 layer applied to the conventional Fe2O3/FTO photoanode to improve the photoelectrochemical performance was assessed from the viewpoint of the microstructure and energy band structure. Regardless of the location of the TiO2 layer in the photoanodes, that is, Fe2O3/TiO2/FTO or TiO2/Fe2O3/FTO, high performance was obtained when α-Fe2O3 and H-TiNT/anatase-TiO2 phases existed in t...
