Erosive potential of powdered juice drinks on dental enamel.

This study aimed to evaluate the erosive potential of powdered juice drinks on dental enamel in 2 stages: physiochemical characterization and erosive challenge testing. In stage 1, the pH and titratable acidity of 5 commercially available powdered juices in 10 different flavors were analyzed. Five treatment groups were then established based on the pH values, titratable acidity, and presence of citric acid in the juices, and their energy-dispersive X-ray (EDX) spectroscopy profiles were studied.

Mechanical and aesthetics compatibility of Brazilian red propolis micellar nanocomposite as a cavity cleaning agent.

Background: Propolis is a natural substance produced by bees and is known to have antimicrobial activity. Our aim was to evaluate the antimicrobial effect of micellar nanocomposites loaded with an ethyl acetate extract of Brazilian red propolis as a cavity cleaning agent and its influence on the color and microtensile bond strength (μTBS) of the dentin/resin interface.

Methods: An ultra-performance liquid chromatography coupled with a diode array detector (UPLC-DAD) assay was used to determine the flavonoids and isoflavones present in an ethyl acetate extract of Brazilian red propolis (EARP) and micellar nanocomposites loaded with EARP (MNRP).

Blastic Plasmacytoid Dendritic Cell Neoplasm with Pulmonary Involvement and Atypical Skin Lesion.

BACKGROUND Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic malignancy neoplasm with highly aggressive course and poor prognosis. This disease typically presents with cutaneous involvement as the first manifestation, with subsequent or simultaneous spread to bone marrow and peripheral blood.  CASE REPORT Here, we report the case of a 51-year-old woman who presented a violaceus skin lesion on the lateral region of the right thigh, weight loss, fever, and lymphadenopathies.

Effect of in-office bleaching with 35% hydrogen peroxide with and without addition of calcium on the enamel surface.

This study aimed to evaluate effectiveness and effects of bleaching with 35% hydrogen peroxide with and without calcium on color, micromorphology, and the replacement of calcium and phosphate on the enamel surface. Thirty bovine enamel blocks (5.0 × 5.

A clinical investigation of the efficacy of a commercial mouthrinse containing 0.05% cetylpyridinium chloride to control established dental plaque and gingivitis.

Objective: The objective of this independent, double-blind, parallel, six-week clinical study was to assess the efficacy of a commercially available mouthrinse containing 0.05% cetylpyridinium chloride (CPC) for controlling established dental plaque and gingivitis relative to that of a control mouthrinse without CPC.

Methods: Adult male and female subjects from the Maceió, Brazil area reported to the clinical facility, after having refrained from any oral hygiene procedures for 12 hours, and from eating, drinking, and smoking for four hours, for an assessment of the oral soft and hard tissues, and for a baseline gingivitis and dental plaque evaluation.
