In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...

This study evaluated the ability of ions from a non-alcoholic calcium hydroxide-propolis paste to diffuse through dentinal tubules. Thirty-six single-rooted bovine teeth were used. The tooth crowns were removed, and the root canals were instrumented and divided into 3 groups: Group 1 - calcium hydroxide-propylene glycol paste; Group 2 - calcium hydroxide-saline solution paste; Group 3 - calcium...

In this study, we construct the hydroxide water cluster, OH-(H2O)6, that (a) could support a stable hydroxide ion with a four-coordinated (pentavalent) hydroxide oxygen and (b) displays hydroxide ion migration. We study the energetic stability and dynamical evolution of the system at different internal temperatures and analyze the corresponding "dynamically averaged" vibrational density of stat...

Introduction Hydroxyl ion release from calcium hydroxide is responsible for the key attributes of broad spectrum antimicrobial activity, penetration into biofilms, inhibition of endotoxins, and dissolution of organic tissues.1,2 The maximum solubility of calcium hydroxide in water at 25C is only 0.159 g/100mL (0.16%), and this reduces to 0.140 g/100 mL (0.14%) at 40C, with an accompanying decre...

Introduction One of the most important factors for successful endodontic therapy is root canal cleaning. The difficulty involved in eliminating microorganisms, as well as their residual presence, warrants the use of root canal dressings after bio-mechanical preparation. Aim The aim of the study was to compare the diffusion ability between nonalcoholic calcium hydroxide-propolis paste, calcium...

hours to several days. We changed the concentration of ammonium hydroxide from 1 mmol/L to 2 mmol/L. We again prepared a standard solution of uric acid at the same molar ratio of 1.7:1 with this concentration of 2-mmol/L ammonium hydroxide. With this ammonium hydroxide concentration, uric acid dissolved completely in a few minutes. The standard solution was stable at least 3 months stored in a ...

The purpose of this investigation was to examine the in vitro susceptibility of Candida albicans to a mixture of chlorhexidine and calcium hydroxide using a tube dilution test. A suspension containing C. albicans was exposed to 2% chlorhexidine solution, calcium hydroxide paste and 2% chlorhexidine mixed with calcium hydroxide in plastic tissue culture wells. The tested agents were incubated wi...

Five disinfectant chemicals were tested individually for effectiveness against low pathogenic avian influenza virus (LPAIV), A/H7N2/Chick/MinhMa/04, on hard, nonporous surfaces. The tested agents included acetic acid, calcium hydroxide, sodium carbonate, sodium hydroxide, and a powdered laundry detergent without bleach. Multiple common chemicals including acetic acid (1 and 3%), sodium hydroxid...
