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 […]

Debonding mechanism of zirconia and lithium disilicate resin cemented to dentin -

To evaluate debonding mechanism of zirconia and lithium disilicate cemented to dentin mimicking what could occur in a clinical setting. A null hypothesis of no difference in tensile bond strength between groups of zirconia and lithium disilicate cemented with resin cements was also tested.
