Effect of Moving the Tip of the Light Curing Unit on the Irradiance Value Delivered. [PDF]

J Esthet Restor Dent
ABSTRACT Objective To determine the effect of differences in the distances and radial positions of the tips of Light‐Curing Units (LCU) on the irradiance values delivered. Materials and Methods Four LCUs—Valo X, Emitter A, CuringPen, and Pinkwave were tested at different distances from the tip (0, 2, 4, 6, 8 mm) and radial displacements (2 and 4 mm ...

UV-Mediated Photofunctionalization of Indirect Restorative Materials Enhances Bonding to a Resin-Based Luting Agent. [PDF]

Biomed Res Int, 2021
Purpose. The potential of UV‐mediated photofunctionalization to enhance the resin‐based luting agent bonding performance to aged materials was investigated. Methods. Sixty samples of each material were prepared. Yttria‐stabilized zirconia (YZr) and Pd‐Au alloy (Pd‐Au) plates were fabricated and sandblasted.

Flexural Strength and Stress Analysis of CAD-CAM Milled Glass Fiber Post and Core [PDF]

International Journal of Dentistry
Intraradicular posts have the potential to induce mechanical stresses within the root structure during masticatory activities, hence contributing to fatigue and ultimately resulting in the fracture of the remaining dental structure. The objective of this work was to compare the stress pattern generated on the root by a computer‐aided design and ...

Granular discharge rate for submerged hoppers [PDF]

, 2014
The discharge of spherical grains from a hole in the bottom of a right circular cylinder is measured with the entire system underwater. We find that the discharge rate depends on filling height, in contrast to the well-known case of dry non-cohesive ...
