A novel etching technique for surface treatment of zirconia ceramics to improve adhesion of resin-based luting cements -

Bonding of zirconia crowns and bridges to abutments is important, not only bonding of the thin resin layer to the abutment, but also bonding to the zirconia ceramic is crucial. Both mechanical and chemical adhesion are desired. Mechanical retention of dental porcelain achieved by etching with moderately concentrated hydrofluoric acid is not possible with zirconia ceramics. The purpose of this study was to show that etching is possible with relative low melting fluoride compounds such as ammonium hydrogen difluoride and potassium hydrogen difluoride.

Anti-biofilm Effect of Dental Adhesive Containing Methacrylated Chitosan -

An experimental dental adhesive incorporated with methacrylated chitosan significantly reduced biofilm formation compared to control, and it may be useful in prevention of secondary caries development.

Relation between In Vitro Toxicity and the Thiol-Reactivity of Methacrylates in Resin-Based Biomaterials -

In this study we aimed to further map the suggested relation between GSH-depletion and methacrylate toxicity by comparing the molecular effects of methacrylate exposure and GSH-depletion by inhibiting GSH-synthesis.

Leakage of Bisphenol A from Dental Materials -

We are daily exposed to a variety of chemicals. One example is the chemical Bisphenol A (BPA). Animal studies indicate that BPA has effects on liver, kidney and breast tissue. Possible endocrine disruption effects contribute to uncertainty around BPA.

The dental monomer hydroxyethyl methacrylate (HEMA) counteracts lipopolysaccharide-induced IL-1β release-Possible role of glutathione. -

HEMA reduced GSH levels and decreased IL-1β release from LPS-stimulated macrophages. The role of GSH in the regulation of IL-1β release was explored. GSH depletion alone could not explain the attenuation of LPS-induced IL-1β release. Electrophile reactivity toward other cellular molecules is a new working hypothesis

Light curing procedures – performance, knowledge level and safety awareness among dentists -

The study aimed to investigate dentists’ exposure to curing light and to obtain information about the dentists’ knowledge on practical use and technical features of their curing lights as well as their safety awareness.
