Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...

Determination of calcium by atomic absorption spectrophotometry applied to the preparation of alginate:chitosan complexes
(2004-12-01)
Polysaccharicles, as alginate and chitosan, have been used to obtain modified release dosage forms. Alginate, due to its property of building gels during the complex formation with calcium ions, allows the building of ...

Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
