The use of silicone in stoma care has grown in recent years and may be considered the next step in the revolutionary development of stoma-care products. Clinical nurse specialists aim to provide evidence-based care at all times, and the same is true for stoma-care nurses. Preventing harm by choosing products that have a sound research base provides the patients with up-to-date, quality care, wh...

The aim of this study was evaluate the dimensional stability of some condensation silicones. The following materials were studied: Coltex/Coltoflax - Coltène, Speedex - Coltène, and Optosil Comfort/Xantopren VL Plus - Kulzer. They were evaluated by dimensional analysis and gas chromatography (GC) performed at the following times: T0, T1, T2, T3, T4, and T5 (immediately after setting, thirty min...

The aim of this work was to use scanning electron microscopy (SEM) to investigate the effect of ampicillin treatment on Escherichia coli biofilms formed on two surface materials with different properties, silicone (SIL) and glass (GLA). Epifluorescence microscopy (EM) was initially used to assess biofilm formation and killing efficiency on both surfaces. This technique showed that higher bacter...

THE STRUCTURE OF hydrogel materials can be described as ‘washingline’ polymers. In this analogy the hydrogels are composed of a long backbone (ie the ‘washing line’) from which a variety of chemical groups may be suspended (the ‘washing’). The function of these chemical groups, or monomers, is to attract and bind water. In conventional hydrogel materials, frequently used monomers include Nvinyl...

Dental microwear analysis is an oft-used paleodietary estimation method, and the impression molds or resin casts are often analyzed rather than original tooth surfaces. A choice of silicone products for dental impressions crucial because quality data affected by accuracy molds. For this reason, researchers have heavily depended on a few commercial such as “President” (Coltène/Whaledent AG, Swit...

Increasingly precise control of polymer architectures generated by “Living” Anionic Ring-Opening Polymerization (Living AROP) is leading to a broad range commercial advanced material applications, particularly in the area siloxane macromers. While academic reports on such materials remain sparse, significant portion global population interacts with them daily basis—in applications including med...
