Streptococcus mutans adhesion and releasing of metallic ions in dental alloys
(Faculdade de Odontologia de Piracicaba - UNICAMP, 2015-03-01)
AIM: To evaluate the adherence of Streptococcus mutans to the surface of the amalgam and copper/aluminum alloy samples and also evaluate the release of metallic ions. METHODS: The prepared medium was changed every 72 h and ...
pH and calcium ion release evaluation of pure and calcium hydroxide-containing Epiphany for use in retrograde filling
(2011-01-01)
Objective: Hydroxyl (OH-) and calcium (Ca++) ion release was evaluated in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3) Epiphany, G4) Epiphany + 10% calcium hydroxide (CH), G5) Epiphany + ...
pH and calcium ion release evaluation of pure and calcium hydroxide-containing Epiphany for use in retrograde filling
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2011-01-01)
Objective: Hydroxyl (OH(-)) and calcium (Ca(++)) ion release was evaluated in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3) Epiphany, G4) Epiphany + 10% calcium hydroxide (CH), G5) Epiphany ...
Synergistic cytotoxic effects of ions released by zinc–aluminum bronze and the metallic salts on osteoblastic cells
(Wiley, 2013-04)
The use of copper-based alloys for fixed dental crowns and bridges is increasingly widespread in several countries. The aim of this work is to study the dissolution of a zinc–aluminum–bronze and the cytotoxic effects of ...
Evaluation of pH and Calcium Ion Release of Root-end Filling Materials Containing Calcium Hydroxide or Mineral Trioxide Aggregate
(ELSEVIER SCIENCE INC, 2009)
Introduction: To evaluate calcium ion release and pH of Sealer 26 (S26) (Dentsply, Rio de Janeiro, RJ, Brazil), white mineral trioxide aggregate (MTA), Endo CPM Sealer (CPM1) (EGEO SRL Bajo licencia MTM Argentina SA, Buenos ...
Evaluation of pH and Calcium Ion Release of Root-end Filling Materials Containing Calcium Hydroxide or Mineral Trioxide Aggregate
(Elsevier B.V., 2009-10-01)

Effective inhibition of the early copper ion burst release by purine adsorption in simulated uterine fluids
(Pergamon-Elsevier Science Ltd, 2016-01)
Burst release of ions from copper-based intrauterine devices (IUD) occurs during the first day after the insertion in uterus and may induce side effects in the users. In the present work, we investigate the mechanism of ...
Reduction of the "burst release" of copper ions from copper-based Intrauterine Devices (IUD) by organic inhibitors
(Elsevier, 2012-01)
The copper intrauterine device is a contraceptive method that is based on the release of copper ions from a copper wire. Immediately after insertion, the dissolution of copper in the uterine fluid is markedly higher ("burst ...
Development of alginate/starch-based hydrogels crosslinked with different ions: Hydrophilic, kinetic and spectroscopic properties
(2019-12-01)
Hydrogels are polymeric materials that have been applied in the controlled release system. The formation of the three-dimensional network may extend the release process. The objective of this study was to optimize the ...
