Influence of Airborne‐Particle Abrasion and Thermal Cycling on Enamel Bond Strength and Roughness of Lithium Disilicate Treated With a Self‐Etching Ceramic Primer

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study investigated the effect of a self‐etching ceramic primer (Monobond Etch & Prime [MEP]), with or without aluminum oxide airborne‐particle abrasion, on the surface roughness, and microtensile bond strength (μTBS) of lithium disilicate bonded to enamel, compared with the conventional hydrofluoric acid plus silane (HF

Generation of Optical Coherent State Superpositions by Number-Resolved Photon Subtraction from Squeezed Vacuum

, 2010
We have created heralded coherent state superpositions (CSS), by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sensor ...

Potential use of oxygen as a metabolic biosensor in combination with T2*-weighted MRI to define the ischemic penumbra [PDF]

, 2008
We describe a novel magnetic resonance imaging technique for detecting metabolism indirectly through changes in oxyhemoglobin:deoxyhemoglobin ratios and T2* signal change during ‘oxygen challenge’ (OC, 5 mins 100% O2). During OC, T2* increase reflects O2

Influence of Superimposition Strategies and Landmark Distribution on the Full‐Arch Trueness of Orthodontic Digital Models

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the influence of superimposition protocols and landmark distribution on deviation outcomes in orthodontic full‐arch models. Materials and Methods Twenty plaster models were scanned using an intraoral and desktop scanner. Ten models were evaluated for landmark suitability and inter‐scanner coordinate agreement.
