Splint Padding Thickness: Temperature Effects and X-ray Visualization.

Objectives: The purpose of this study was to determine if the thickness of splint padding could be determined on X-rays, and whether increasing layers of splint padding have an effect on temperature at the skin after placement.

Methods: Both in vitro and in vivo testing was performed. Ten cadaveric lower extremities were used.

Improved bonding of zirconia substructures to resin using a "glaze-on" technique.

Objective: To investigate the influence of applying thin intermediary coatings of acid-etchable glasses on the shear bond strength between a methacrylate resin based cement and an yttria-stabilized zirconia dental ceramic substrate.

Methods: The upper and lower surfaces of 110 sintered yttria-stabilised tetragonal zirconia polycrystalline disc-shaped specimens were polished using sequential grades of Silicon Carbide, then air-abraded with 25 μm diameter alumina particles. Specimens were randomly allocated to 11 groups (A-K) (n=10), group A acting as control.
