Cu-doped amorphous calcium phosphate (ACP) coatings were fabricated on the surface of pure titanium (Ti) by electrochemical deposition at initial electrolyte temperatures 35, 45, and 55°C. The antibacterial activities then evaluated plate counting method using Escherichia coli as indicator. Cu concentrations surfaces samples are increased from 6.90 to 15.05 mass% temperature is 35 ACP show that...

Calcium phosphate bioceramics, such as hydroxyapatite, have long been used as bone substitutes because of their proven biocompatibility and bone binding properties in vivo. Recently, a zirconia-hybridized pyrophosphate-stabilized amorphous calcium phosphate (Zr-ACP) has been synthesized, which is more soluble than hydroxyapatite and allows for controlled release of calcium and phosphate ions. T...

The study is about evaluating the effects of three remineralising agents i.e. Casein Phosphopeptide - Amorphous Calcium Phosphate [CPP-ACP], Sodium fluoride varnish and Tricalcium phosphate (TCP) on dentin. objective this to see which have a better effect In study, thirty freshly extracted human central incisors are selected with exposed labial surfaces each tooth divided into four quadrants tr...

Vacuum foam drying is evaluated as an alternative for lyophilization for enhanced process and storage stability of bovine serum albumin. The protein protective efficiency of different stabilizers was compared in vacuum foam drying and lyophilization. Sucrose mixtures produced better foam characters than mannitol. Unlike calcium lactate, incorporation of polyvinyl pyrrolidone to sucrose synergis...

OBJECTIVE To determine whether an amorphous calcium phosphate (ACP)-containing adhesive has an acceptable level of shear bond strength to be used as an orthodontic adhesive. MATERIALS AND METHODS Sixty extracted premolars were randomly divided into three groups for orthodontic bonding. Group 1 used a composite resin adhesive (Transbond XT), group 2 was bonded with an ACP-containing adhesive (...

Improving the anti-demineralizing/remineralizing and mechanical properties of amorphous calcium phosphate (ACP) composites has been the focus of our recent research. In this study, an ethoxylated bisphenol A dimethacrylate (EBPADMA) was blended with triethylene glycol dimethacrylate (TEGDMA), 2-hydroxyethyl methacrylate (HEMA) and methacryloxyethyl phthalate (MEP) to form experimental resins wi...

In the past, the two major biomineralization motifs, biosilicification and biocalcification, were considered as two discrete processes. However, there is increasing evidence of the existence of an inextricable relationship between biosilica and calcium-based biominerals. The recent discovery of a unique silica–chitin–aragonite biocomposite in one genus of demosponges (Verongida) introduces a no...

AIMS to design calcium and zinc-loaded bioactive and cytocompatible nanoparticles for the treatment of periodontal disease. METHODS PolymP-nActive nanoparticles were zinc or calcium loaded. Biomimetic calcium phosphate precipitation on polymeric particles was assessed after 7 days immersion in simulated body fluid, by scanning electron microscopy attached to an energy dispersive analysis syst...

Genetic evidence from mutant mice suggests that alpha(2)-HS glycoprotein/fetuin-A (Ahsg) is a systemic inhibitor of precipitation of basic calcium phosphate preventing unwanted calcification. Using electron microscopy and dynamic light scattering, we demonstrate that precipitation inhibition by Ahsg is caused by the transient formation of soluble, colloidal spheres, containing Ahsg, calcium, an...
