Reason for loosening of ceramic restorations - The resin cement forms the weakest link for a ceramic restoration. This was found in an investigation of the de-bonding of resin cementation of zirconia or lithium di-silicate ceramic to bovine dentin.
Peroxide-free tooth whitening - The peroxide-free tooth whitening products are less effective than those based on peroxides and the effect is only transitory. Both peroxide-free and peroxide containing products gave an initial lightening of the tooth color. However, the effects of peroxide-free products were only transitory.
Digital dentistry - Digital manufacturing using intraoral scanners appears to provide equivalent fit compared to conventional technique for smaller prosthetic constructions. Milled composites have a less toxic potential compared to traditional light cured directly placed composite restorations.

Effect of methacrylated chitosan incorporated in experimental composite and adhesive on mechanical properties and biofilm formation - The results of this study show that CH-MA (CH-MA) may be incorporated into a composite and into an adhesive to reduce biofilm formation on their surfaces. The mechanical properties of the composite were challenged, but flexural strength measurements still met the requirement set in ISO 4049, whereas no differences were observed for the bonding properties of the adhesives.
Thermal induced deflection of a porcelain–zirconia bilayer: Influence of cooling rate - To determine the thermal expansion of a porcelain (VM9) and tetragonal zirconia (Y-TZP) as well as the deflection upon re-heating and cooling of a bilayer fabricated from these two materials after slow and rapid cooling during initial fabrication.
Bleaching of the Discolored Traumatized Tooth - This chapter in “Textbook and Color Atlas of Traumatic Injuries to the teeth” focuses on the treatment of discolored traumatized teeth, most of them being non‐vital and subsequently, endodontically treated. Tooth bleaching based upon hydrogen peroxide as the active agent, applied directly or produced in a chemical reaction from sodium perborate or carbamide peroxide, must […]
