Preparation of a fluorinated dental resin system and its anti-adhesive properties against S. mutans -

Resin system prepared exclusively with fluorinated methacrylate monomers reduced the S. mutans adhesion due to their increased hydrophobicity and decreased surface energy. Compared with Bis-GMA/TEGDMA, the FDMA/FBMA resin system also exhibited higher double bond conversion and lower water sorption and solubility

Preparation and characterization of Bis-GMA-free dental composites with dimethacrylate monomer derived from 9,9-Bis[4-(2-hydroxyethoxy)phenyl]fluorene. -

New dimethacrylate monomer Bis-EFMA was synthesized and used to prepare Bis-GMA-free dental resin and composite materials. Studies of the experimental materials showed that Bis-EFMA-based resin matrix and composite materials had improved properties compared to Bis-GMA-based resin matrix and composite materials, respectively. Compared with the commercial dental composite material Z250, Bis-EFMA-based composite showed similar or improved properties except for a lower FS after water immersion. Based on the presented results, Bis-EFMA has potential to be used in commercial dental composites.

A review of data collected for polymer-based restorative materials in the period 2005-2011. -

Forty-two randomly picked materials with some of the shades available were examined for depth of cure, flexural strength, water sorption and water solubility, and shade and color stability.

Evaluation of two matrix materials intended for fiber-reinforced polymers -

Abstract: Two matrix resins for fiber composites that remain in a fluid state during storage and handling before polymerization were evaluated. The resin mixtures, based on methyl methacrylate (MMA), were produced with two different cross-linking agent systems: 1,4-butanediol dimethacrylate and ethylene glycol dimethacrylate or diethylene glycol dimethacrylate. Water sorption, water solubility, water uptake and residual […]

Water sorption and solubility of dental composites and identification of monomers released in an aqueous environment. -

The resin composition influences the water sorption and solubility behaviour of composite resin materials. The HPLC analysis of eluted components revealed that triethyleneglycol dimethacrylate (TEGDMA) was the main monomer released. Maximal monomer concentration in the eluate was observed after 7 days.
