Effect of electrical spot welding on load deflection rate of orthodontic wires.

Background: One of the methods used for joining metals together is welding, which can be carried out using different techniques such as electric spot welding. This study evaluated the effect of electric spot welding on the load deflection rate of stainless steel and chromium-cobalt orthodontic wires.

Materials And Methods: In this experimental-laboratory study, load deflection rate of 0.

Effect of ferric sulfate contamination on the bonding effectiveness of etch-and-rinse and self-etch adhesives to superficial dentin.

Aim: This study investigated the effect of one hemostatic agent on the shear bond strength of self-etch and etch-and-rinse adhesive systems.

Materials And Methods: Sixty extracted third molars were selected. After preparing a flat surface of superficial dentin, they were randomly divided into six groups.
