Effect of Successive Bleaching Treatments Followed by Staining on Color, Whiteness, and Translucency of Polymer‐Based CAD‐CAM Materials

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate differences in color, whiteness, and translucency of CAD‐CAM materials after successive bleaching treatments and coffee immersion. Materials and Methods Lava Ultimate (LU) and VITA Enamic (VE) were divided into four groups (n = 12): untreated (control), 35% hydrogen peroxide (WH), 10% carbamide peroxide (OP), or WH ...

One‐Year Color Stability of a Reduced 37.5% Hydrogen Peroxide In‐Office Bleaching Protocol: A Randomized Clinical Trial

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This randomized clinical trial evaluated the one‐year color stability and patient satisfaction regarding dental esthetic improvement after 37.5% hydrogen peroxide (37.5HP) in‐office bleaching with a reduced application protocol. Materials and Methods Forty participants with a shade mean C2 or darker were randomly allocated into two ...

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

open access: yesJournal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Shade variability and stability in interim and definitive tooth‐colored resin‐based restorative materials: Comparing manufacturer‐claimed shades to a universal shade guide

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the shade variability and stability of interim and definitive tooth‐colored restorative materials by comparing manufacturer‐claimed shades to a universal shade guide before and after thermocycling. Materials and Methods Eight commercially available tooth‐colored restorative materials were tested, including conventional ...
