Wettability of saliva substitutes across various denture base fabrication techniques.

Purpose: The present study evaluated the contact angles (CAs) of four denture base materials subjected to different surface treatments using deionized water and saliva substitutes.

Material And Methods: A total of 32 rectangular specimens were manufactured using four different denture base materials: heat-cured compression molded Lucitone 199 (C), milled Lucitone 199 (M), Formlabs Denture Base RP (P), and SR Ivocap High Impact (I). The CA of the surface of the unaltered, mechanically polished, and sandblasted surface specimens was evaluated after the application of five saliva substitutes: Biotene, VEGA, Spry, Moi-Stir, Dentilube, and ionized water.

Computational Image Analysis of Nonenhanced Computed Tomography for Acute Ischaemic Stroke: A Systematic Review.

Background: Noncontrast enhanced computed tomography (NCCT) remains the most common method for brain imaging patients who present acutely with ischaemic stroke. Computational methods may improve NCCT analysis in this context. We systematically reviewed current research.

Bronchiectasis as a Cause of Elevated CA-19-9 Demonstrated on 18F-FDG PET/CT.

A 64-year-old woman with a history of weight loss and a markedly elevated serum carbohydrate antigen 19-9 level of 560 U/mL was referred for an F-FDG PET study to evaluate for occult malignancy. In addition to the weight loss, she had suffered from a chronic cough secondary to bronchiectasis and had been investigated for a suspected gastrointestinal malignancy. Multiple FDG-avid foci were detected throughout both lungs on FDG PET, corresponding to areas of bronchiectasis on CT with no obvious suspicious FDG-avid foci elsewhere.
