Effects Of Fluoride On Corrosion Properties Of Orthodontic Retention Wires, John J. Simindinger
Master's Theses (2009 -)
Objective: Alloys used in retention wires corrode in the oral environment. Previous studies have examined the effects of fluoride on archwires used in active treatment, but not on retention wires. The goal of this study was to determine what effect fluoride exposure has on corrosion of various lingual bonded retainer wires in the mouth. Methods: Twenty samples from six different wire types were tested in two solutions. Half were tested in Fusayama-Meyer artificial saliva, while the other half were tested in Fusayama-Meyer plus fluoride correlated to the concentration of toothpaste. A potentiostat was used to measure open circuit potential (OCP) …
