This study evaluated the effect of the addition of 5% calcium chlorite (CaCl2) on pH values in calcium hydroxide pastes (CH), with or without 2% chlorhexidine digluconate (CHX) used as vehicle, in several periods analysis. ...

Studies carried out with glass electrode in anhydrous ethanol and ethanol-water solutions for measuring pH values have shown that this parameter depends on the solution composition, the contact time with the solution, the ...

We studied the behavior of different pH values of Rhodamine B solution impregnated into pores of mesoporous silica, through structural characterization techniques, such as scanning electron microscopy and porosity measurements, ...

Introduction: Alkalinization potential is a fundamental property of endodontic epoxy-based cements containing calcium hydroxide. Studies have shown discrepant pH results for same materials at different evaluation periods. ...

Based on van’t Hoff and Gibbs equations, thermodynamic functions Gibbs energy, enthalpy, and entropy of solution and mixing of 6-methylcoumarin in water at pH 1.2, 6.8, and 7.4, were evaluated from solubility values ...

Calcium binding to triads isolated from rabbit skeletal muscle followed a single hyperbolic function in the pH range 5.5-8.0. Maximal binding was obtained at pH 8.0; decreasing the pH decreased the binding capacity and, ...

Introduction: The aim of this study was to compare the effect of four different salivary pH levels on the shear bond strength (SBS) of two orthodontic adhesive systems for bracket placement. Materials and Methods: This ...
