"Introduction: In the oral environ-ment, orthodontic appliances are exposed to potentially damaging physical and chemical agents which may cause metallic corro-sion. Corrosion will occur contin-uously in mouth, due to release of irons with abrasion by food, liq-uids etc. The purpose of this study was to measure the amount of metal ion release from orthodontic brackets when kept in different mouthwashes and effect of tulsi rinse on ion release when com-bined with different mouthwashes.
Methods: Three hundred and twen-ty stainless steel brackets (0.022”) were divided randomly into 8 equal groups and immersed in Mouthwash-A and, Mouthwash-B and mouthwash-C and distilled deionized water. These mouth-washes and distilled deionized wa-ter were all separately mixed with tulsi rinse and incubated at 37°C for 45 days. Nickel, Chromium, iron, copper and manganese re-leased from the orthodontic brack-ets were measured with an induc-tively coupled plasma spectrome-ter.
Results: Ion release in deionized water was higher (p0.05) in nickel, chromium, iron and copper ion release in the Mouthwash-A and Mouthwash-C. Tulsi rinse showed significant re-duction (p
