Background and objectives: The aim of the study was to investigate the nickel and chromium ion release from the different brands of stainless steel brackets in to the normal saline. Materials and Methods: Five full set of Dentaurum,3M and Koden brackets were immersed in sterile plastic tube and marked A,B,C respectively, containing 50ml of Normal saline and maintained at 37°c for 3 weeks. The processing was done by using 0.5ml of saliva that was transferred to a 2ml plastic test tube with a micropipette. The chemical analysis for Ni and Cr is performed with an Atomic Absorption Spectrometer. The concentration of Ni and Cr are expressed in micrograms per litre.This process was done by 1st,7th,14th and 21st day. The values are analyzed. Results: The nickel and chromium release of Koden brackets is high. The least release of nickel and chromium is observed in Dentaurum brackets. The chromium release is insignificant within the groups but it significant in duration of days. The nickel release is significant within the groups but it is insignificant in duration of days. Interpretation and Conclusion: Nickel and chromium release from different company brackets are not uniform, it varies. Koden brackets show more amount of nickel release, Dentaurum brackets show least amount of Nickel release.
