Clinical Study on the Efficacy of 35% Hydrogen Peroxide Gel According to Exposure Time (40 min vs. 20 min) by Spectrophotometry

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To analyze the chromatic effect on CIELAB coordinates and the clinical effectiveness of in‐office whitening treatment (perceptible changes) with 35% hydrogen peroxide (HP) gel according to the number of clinical sessions and exposure time (40 min vs. 20 min) in the three thirds of the tooth.

Reliability of Three Image‐Based Instrumental Color‐Measurement Methods

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To compare the precision of three clinically applicable, image‐based color assessment methods—smartphone imaging, a clinical colorimeter (Optishade), and a digital scanning device (Borea Cobra)—against a benchtop spectrophotometer for measuring CIELAB coordinates and CIEDE2000 (ΔE00) color differences of composite resin shades ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Synthesis of the heterocyclic core of the D-series GE2270

Beilstein Journal of Organic Chemistry, 2017
A straightforward enantiomerically pure synthesis of the heterocyclic core of the D-series GE2270 is reported. The synthetic strategy combines the Hantzsch thiazole’s building condensation with a cross-coupling reaction including direct C–H hetarylation ...
