Aim: To determine the presence of Nickel, released from orthodontic arch wires, in the human saliva by inductively coupled plasma – atomic emission spectroscopy (ICP-AES) Materials and Method: 39 subjects were equally divided into three groups A, B and C. Groups A and B were bonded with Pre adjusted Edgewise brackets 0.018” slot. Group A received uncoated NiTi arch wires and Group B received coated NiTi arch wires while Group C without orthodontic appliances served as controls. 3ml of salivary samples were collected from each subject one on the end of first month and the other on the end of second month of treatment and was stored at - 20° C. Saliva sampling was done and centrifuged at 7000 rpm for 10 minutes. Presence of Nickel in the given samples was analyzed by Inductively Coupled Plasma – Atomic Emission Spectroscopy. Results: The mean Nickel levels in the saliva released from Uncoated NiTi wires were significantly higher than coated NiTi wires and control group.
Keywords: Atomic Emission Spectroscopy, Inductively Coupled Plasma, orthodontics.
