Evaluation of mechanical properties of NiTi orthodontic wire after immersion in three different mouthwashes

Introduction: Since orthodontic therapy may have detrimental effects to the tooth structures or periodontium, practitioners recommend their patients to use different mouth washes. These chemical agents may be potentially damaging to metal components of orthodontic appliances. The aim of the present study was to evaluate the effect of three common mouthwashes on mechanical properties of NiTi orthodontic wires.
