Bioceramics are materials which include Alumina, Zirconia, Bioactive glass, Glass ceramics, Hydroxyapatite, resorbable Calcium phosphates, among others. They have been used in dentistry for filling up bony defects, root repair materials, apical fill materials, perforation sealing, as endodontic sealers and as aids in regeneration. They have certain advantages like biocompatibility, non toxicity...

Hydroxyapatite (HA), a material proven to be biocompatible within the human body, has been produced to a high level of purity. This material has been applied as a coating on Ti-6Al-4V alloy by using the air plasma spraying technique. The coat was characterizted with SEM, XRD, FTIR and Raman spectroscopy methods to consist of a mixture of calcium phosphates including HA mainly and traces of tric...

Calcium phosphates like hydroxyapatite (HA), beta-tricalcium phosphate (beta-TCP), and their mixtures (biphasic calcium phosphates; BCP) are used clinically to repair bone defects. These materials can be difficult to handle and have no inherent biological activity. Handling properties of other bone substitute materials have been improved by combining them with an inert carrier such as Pluronic ...

The process of aging and escalating the failure all body organs has become center interest in contemporary science medicine. leading role phosphate-calcium tandem deficiency as a pacemaker metabolic senescence emerged recently. Most phosphates human are stored bones, which seem to play pivotal energetic processes. Bone metabolism combines physical activity with adaptive changes internal environ...

objectives: the purpose of this study was to consider the effect of eight weeks aerobic training on pth, albumin, calcium, alkaline phosphatesand estrogen levels in postmenopausal women. methods & materials: 22 postmenopause women, 55-70 years, of jahandidegan center in tehran were selected and randomly divided into two groups: (experimental (12) and control (10)) .they had aerobic training pro...

Abstract Objective: to describe the results from intravenous calcium loads in patients with suspected PHPT. Methods: This was a retrospective cross-sectional study inpatients’ data review. Baseline serum calcium, phosphates, magnesium, creatinine, alkaline phosphatase, beta-crosslinks were recorded. The loading had been performed after an overnight fasting. Calcium gluconate 0.25 mmol/kg body w...
