Purpose: The purpose of this in vitro study was to evaluate and compare the fracture strengths of post and core systems produced with different fabrication techniques and materials.
Methods: Forty extracted human single-root premolars were used in this study. After root canal treatment, the teeth were randomly divided into 4 groups of 10 each as follows: group C: metallic 1-piece posts and cores fabricated by casting, and serving as the control; group CM: metallic posts and cores fabricated with the copy milled technique; group LS: 1-piece posts and cores fabricated with the laser sintering technique; and group ZR: 1-piece zirconia posts and cores fabricated with computer-aided design and computer-aided manufacturing (CAD-CAM).
Objective: The purpose of this in vitro study was to evaluate the influence of different power outputs of a carbon dioxide (CO2) laser on shear bond strength of resin cement to zirconium dioxide-based ceramic.
Materials And Methods: Fifty zirconium dioxide core specimens (10 mm diameter and 2 mm thickness) were produced and they were embedded in the centers of auto-polymerizing acrylic resin blocks. Ten specimens served as control and no surface treatment was applied.
Objective: The aim of this randomized controlled clinical trial was to determine the anxiety levels of patients with recurrent aphthous stomatitis (RAS) prior to therapy with the Nd:YAG laser or medication, and to compare the effects of these different treatment methods on the degree of post-treatment pain, discomfort, and functional complications (eating and speech) experienced.
Materials And Methods: Twenty patients with RAS-related oral problems were included in the study. Levels of pre- and post-treatment pain and functional complications were assessed at patient visits on days 1, 4, and 7.
