Abstract Introduction: One-bottle light-cured adhesives systems have variable pH. In addition to ease of use, universal adhesives can be used in various restorations and different substrates. Due to the lack of studies, the purpose of this study was to compare the enamel and dentin micro-leakage of self-cure and light cure composite restorations using a universal bonding system. Materials...

BACKGROUND Treatment guidelines recommend stopping all implicated antibiotics at the onset of Clostridium difficile infection (CDI), but many individuals have persistent or new infections necessitating the use of concomitant antibiotics (CAs). We used data from 2 phase 3 trials to study effects of CAs on response to fidaxomicin or vancomycin. METHODS Subjects with CDI were treated for 10 days...

introduction: the aim of this study was to evaluate the influenceof different light curing systems and curing times on the micro-hardness of aresin modified glass ionomer. methods: forty two samples of resinmodified glass ionomer (rmgi) were prepared using stainless steel cylindrical mold(8 × 2 mm) and randomly divided into six groups of seven. three groups werecured with a quartz tungsten halo...

In the electronics industry epoxy molding compounds, underfills and adhesives are used for the packaging of electronic components. These materials are applied in liquid form, cured at elevated temperatures and then cooled down to room temperature. During these processing steps residual stresses are built up resulting from both cure and thermal shrinkage. These residual stresses add up to the st...

The increasing use of composite materials has led to a greater demand for efficient curing cycles to reduce costs and speed up production cycles in manufacturing. One method to achieve this goal is in-line cure monitoring to determine the exact curing time. This article proposes a novel method through which to monitor the curing process inside closed tools by employing ultrasonic spectroscopy. ...
