PURPOSE The purpose of this study was to investigate the in vivo effects of a new smart polymer loaded with dexamethasone on inflamed rabbit eye. MATERIALS AND METHODS Polymeric micelles were prepared using N-isopropylacrylamide (NIPAAM), vinyl pyrrolidone (VP), and methacrylate (MAA) as monomers in the presence of N,N-methylene bis-acrylamide (MBA) and triethyleneglycol dimethacrylate (TEGDM...

OBJECTIVES This study investigated the stability of compounds of dental sealant materials in a salivary matrix. METHODS Various amounts of bisphenol A (BPA), bisphenol A dimethacrylate (BIS-DMA) or triethylene-glycol dimethacrylate (TEGDMA) were added to whole salivary samples, and stored at -70 degrees C or -20 degrees C for up to 4 months. In other experiments, four separate whole salivary ...

This study sought to evaluate the in vitro biological response of human gingival fibroblasts (HGFs) co-coltured with Streptococcus mitis to bisphenol A glycidylmethacrylate/triethylene glycol dimethacrylate (BisGMA/TEGDMA) thermosets coated with Chitlac-nAg, a nanocomposite system with antimicrobial properties. To avoid bacterial adhesion to dental devices and to reduce cytotoxicity against euk...

As frequently added to adhesives, the mono-functional monomer 2-hydroxyethyl methacrylate (HEMA) acts as co-solvent and improves surface wetting. Nevertheless, HEMA promotes watersorption hydrolysis at adhesive interfaces, affecting bond durability dentin. This study investigated if two acrylamide co-monomer alternatives could replace in experimental adhesive-resin formulations part of 3/2-step...

This study was to evaluate the acid-buffering capacity and antibacterial properties of orthodontic adhesives containing bioactive glasses (BAGs) (45S5, 45S5F, S53P4), Hydroxyapatite, beta-tricalcium phosphate, Canasite. Fillers comprising 15 wt% glasses, HAp, β-TCP, Canasite incorporated with 55 silanated glass were added a mixture UDMA/TEGDMA. Acid-buffering tested by exposing disc-shaped samp...
