Universal adhesive application to contaminated/non-contaminated dentin with three different protocols: An in vitro shear bond strength and SEM analysis.

This study aimed to comparatively evaluate the shear bond strength (SBS) of a universal adhesive to contaminated/non-contaminated dentin when applied with three different protocols. One-hundred-eighty dentin samples were divided randomly into 12 groups (n=15). The groups were created by combining four dentin contamination conditions (non-contaminated or contaminated with blood, hemostatic, or blood+hemostatic) with three application protocols for Single Bond Universal (no-preconditioning or preconditioning with the 35% phosphoric or 1% gallic acid).

Anti-inflammatory effect of lycopene on endotoxin-induced uveitis in rats.

Purpose:: We evaluated the efficacy of lycopene, a dietary carotenoid and potent antioxidant, against ocular inflammation and oxidative stress in an experimental uveitis model.

Methods:: Endotoxin-induced uveitis (EIU) was induced in Sprague-Dawley rats by a single subcutaneous injection of 200 μg lipopolysaccharide (LPS). Induction of EIU was preceded by daily intraperitoneal injection of 10 mg/kg lycopene for three consecutive days (Lycopene + LPS group) or equivolume vehicle (Vehicle + LPS group).

A Comparison of Central Corneal Thicknesses Measured with Two Different Methods in Cases of Primary Open-Angle Glaucoma.

Accurate and repeatable measurement of the central cornea thickness (CCT) is important in terms of follow-up of glaucoma patients. The aim of this study was to compare CCT measurements made with an ultrasonic pachymeter (USP) and with the Spectralis Anterior Segment Module optical coherence tomography (OCT) device. The study included 52 eyes of 26 primary open-angle glaucoma patients.

Fonsecaea pedrosoi as a rare cause of acute conjunctival ulceration.

Conjunctival ulceration accompanied with secretion and pain was observed in a 30-year-old male, 3 days after a perforating corneal trauma. Cultures of conjunctival ulcer samples grew Fonsecaea pedrosoi, a major causative agent of chromoblastomycosis that is typically transmitted during trauma. The conjunctival ulcer was successfully treated with amphotericin B, itraconazole, and fluconazole.
