Fluoride release and absorption at different pH from glass-ionomer cements.
OBJECTIVE The aim of this study was to evaluate the fluoride release (release-tests) from two glass-ionomer cements (GIC), before and after NaF solution treatment (fluoride treatment) in different pHExpand

Tunnelling methods and Hawking's radiation: achievements and prospects
The aim of this work is to review the tunnelling method as an alternative description of the quantum radiation from black holes and cosmological horizons. The method is first formulated and discussedExpand

Permeability of marginal hybrid layers in composite restorations
The goal of adhesive dentistry is to restore the peripheral seal of dentin lost from removal of enamel. Unfortunately, the hybrid layer (HL) that is used to create that seal is permeable to smallExpand

Unruh–DeWitt Detectors in Spherically Symmetric Dynamical Space-Times
In the present paper, Unruh–DeWitt detectors are used in order to investigate the issue of temperature associated with a spherically symmetric dynamical space-times. Firstly, we review theExpand

On the implications of the Bekenstein bound for black hole evaporation
We elaborate on the possible impact of the Bekenstein bound on the unitarity of black hole evaporation. As such maximal bound on the entropy of any system may be regarded as due to the existence ofExpand

In vivo Fluid Movement through Dentin Adhesives in Endodontically Treated Teeth
Fluid transudation through simplified dentin adhesives can occur in bonded vital crown dentin, since these adhesives behave as permeable membranes after polymerization. The effect of adhesiveExpand

Recovery of Enterococcus faecalis in root canal lumen of patients with primary and secondary endodontic lesions.
The presence of Enterococcus faecalis in root canal teeth affected by primary and secondary periapical lesions was studied using polymerase chain reaction (PCR) assays. The association betweenExpand
