Tooth Bleaching Increases Dentinal Protease Activity [PDF]

Journal of Dental Research, 2012
Hydrogen peroxide is an oxidative agent commonly used for dental bleaching procedures. The structural and biochemical responses of enamel, dentin, and pulp tissues to the in vivo bleaching of human (n = 20) premolars were investigated in this study. Atomic force microscopy (AFM) was used to observe enamel nanostructure.

Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

Small, EarlyView.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
