Abstract

Background:  Release of nickel and chromium ions into saliva can occur due to the corrosion of orthodontic alloys which may influence on systemic levels.3 Exposure biomarkers are used to measure the systemic effects. Medium for systemic exposure with reasonable sensitivity might be gingival crevicular fluid (GCF).  Materials and Methods: The PerioPaper strips were gently placed in the sulcus for 60 seconds. If bleeding was observed at the site of examination, that site was discarded and other site was selected for the examination. After 60 seconds, the strip in the sulcus was removed and placed in a glass container with covered top.  Results: The mean age of the patients was 24.3+3.1 years, ranging from 15-32 years. There is a significant increase in the mean level of nickel from 1st visit to 3rd visit and from 2nd visit to 3rd visit. The number of patients with moderate or severe inflammation increased with simultaneous decrease in patients with normal healthy gingivae or mild inflammation.  Conclusion: Patients with fixed orthodontic treatment has increased concentration of nickel and chromium in the GCF. We also observed that the gingival health also deteriorates with subsequent visits.
