The aim of this study was to analyze the levels of nickel and chromium in GCF and hair of orthodontic patients. Nickel and chromium ion concentrations were measured in GCF and hair of 15 patients (9 females and 6 males, aged 16-28 years old) who had fixed orthodontic treatment using Atomic Absorption Spectroscopy. The samples were taken before treatment (baseline) and four months later during treatment. Data were analyzed using paired t-tests and Pearson correlation test. GCF nickel level increased from 3.39 μg/g (baseline) to 9.00μg/g (4 months); chromium level increased from 1.88 μg/g (baseline) to 6.85 μg/g (4 months). Both of these increases were significant (paired t-test, P=0.000). Hair nickel level increased from 0.14 μg/g (baseline) to 0.42μg/g(4 months); chromium level increased from 0.09 μg/g (baseline) to 0.11 μg/g (4 months). Both of these increases were significant (paired t-test, P=0.000) There was no significant correlation between the increase of ion level in GCF with that in hair. After 4 months of treatment with fixed orthodontic appliances, GCF nickel and chromium levels might increase about 364% and 265%, respectively and hair nickel and chromium levels might increase about 122% and 300%, respectively. There was no significant correlation between the difference (increase) of GCF nickel and chromium levels with the increase of hair nickel and chromium levels. [ABSTRACT FROM AUTHOR] |
