Release and diffusion of hydroxyl ion from calcium hydroxide-based medicaments
(Wiley-Blackwell, 2012-08-01)
The release and diffusion of hydroxyl ions (OH-) of calcium hydroxide (Ca(OH)2)-based intracanal medications may be affected by the association with other substances. The aim of this study was to evaluate the diffusion of ...
Preparation and characterization of poly(ε-caprolactone) nanospheres containing the local anesthetic lidocaine
(2013-01-01)
The objective of this work was to develop a modified release system for the local anesthetic lidocaine (LDC), using poly(ε-caprolactone) (PCL) nanospheres (NSs), to improve the pharmacological properties of the drug when ...
pH, Calcium Ion Release, and Setting Time of an Experimental Mineral Trioxide Aggregate-based Root Canal Sealer
(Elsevier B.V., 2011-06-01)
Introduction: An experimental mineral trioxide aggregate sealer (MTAS) has been developed for use as a root canal sealer. The aim of this study was to evaluate the setting time, pH, and calcium ion release of MTAS compared ...
Modified drug release system based on Sulindac and layered double hydroxide: An in vivo Raman investigation
(Elsevier Science Bv, 2016)
In this study, the capability of a Layered Double Hydroxide (LDH) to promote the modified-release of Sulindac (Sul), a non-steroid anti-inflammatory drug, was followed by Raman spectroscopy through in vitro and in vivo ...
Liberação de cálcio e magnésio por cápsulas porosas de porcelana usadas na extração de solução do solo
(Sociedade Brasileira de Ciência do Solo, 2004-08-01)
O uso de cápsulas porosas para extração de solução do solo é interessante por ser um ensaio não-destrutivo. Entretanto, persistem dúvidas sobre a liberação de íons da própria cápsula, que podem contaminar a solução extraída. ...
Fluoride release/recharge from restorative materials: effect of fluoride gels and time
(Operative Dentistry Inc, 2005-11-01)
This study examined the differences in fluoride release and recharge among four restorative materials following treatment with APF or neutral fluoride gel for one or four minutes. Specimens were immersed in 2 mL of deionized ...
