Optimizing quality and safety of dental materials -

Optimizing quality and safety of resin‐based materials need coherent strategies. Proper handling and polymerization increase the rate of conversion and thus minimize the content of residual monomers. Measures to reduce biofilm accumulation at the tooth‐restoration interface could prevent or reduce the most common reason for restoration failure, recurrent caries.

Toxicity of plast materials -

The term «resin-based dental materials» refers to dental materials containing polymers. Usually, these polymers are formed by in situ polymerization of methacrylate monomers.

Comparison of Different Etching Agents and Repair Materials Used on Feldspathic Porcelain -

When fractures of fixed partial dentures occur, they cause an aesthetic and functional dilemma both for the patient and the dentist. Re-make of the entire restoration is an option, but not always desirable. The aim of this study was to test the shear bond strength due to four different etching agents for ceramic repair.

Polymer based restorative materials – a study of important properties -

The composition, leachable products, and physical properties of toothcoloured restorative materials have been determined. The composition was often found to be more complex than described in the MSDS of the materials. The most frequently used monomers such as TEGDMA, Bis-GMA, Bis-EMA, UDMA, and 2-HEMA were detected, as well as several other monomers and different additives (initiators, activators, and stabilizers). The initiator camphoroquinone was found in all the investigated materials. B

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.
