Abstract

Background:  Almost all fixed metallic orthodontic appliances comprise metals, such as nickel (Ni), chromium (Cr), and cobalt. The present study aimed to assess amount of nickel and chromium in saliva in patients with fixed orthodontic appliances.  Materials & Methods: The present study was conducted on 20 patients undergoing fixed orthodontic treatment of both genders. Saliva was collected before treatment, after completion of alignment and leveling with nickeltitanium wires and after 12 months.  The samples were kept at −20°C. The concentration of both nickel and chromium ions was recorded in parts per billion (ppb) using inductively coupled Plasma‑Mass Spectrometer. Results: Out of 20 patients, males were 8 and females were 12. Pre- treatment value of nickel was 42.8 ppb, post- alignment was 58.6 ppb and after 12 months was 50.4 ppb. The difference was significant (P< 0.05). Pre- treatment value of chromium was 72.4 ppb, post- alignment was 94.6 ppb and after 12 months was 84.2 ppb. The difference was significant (P< 0.05). Conclusion: Author found that there was significant increase in nickel and chromium ion concentration in saliva of patients undergoing fixed orthodontics.
