Introduction: Stainless steel used for fabrication of various components of fixed orthodontic appliances interact to oral environment and releases metal ions including nickel and chromium, absorbed systemically can cause side effects to the body if their concentration exceeds above
toxic dose.
Aim: To determine and compare the level of nickel and chromium in serum of patients undergoing fixed orthodontic treatment at different time period.
Materials and Methods: Serum sample of 13 patients was taken before (Group I) and after one week (Group II), one month (Group III) and three month (Group IV) of appliance placement. Level of nickel and chromium ion was determined using Graphite Furnace Atomic Absorption Spectro-photometry. Data was statistically analyzed using SPSS Statistical Analysis Software (Version15.0).
Results: Serum level of nickel and chromium was highest in Group II and lowest in Groups I. On comparison among different groups, statistically significant difference was found between Groups I vs II, III and IV (p<0>
(<0>
Conclusion: The serum nickel and chromium level was maximum after one week of appliance placement then gradually declined. This level was well below the toxic dose of these ions.
