Evaluation of Nickel Ion Release from Orthodontic Wires in Different Types of Artificial Saliva
Aims: To evaluate the amount of nickel ion release from stainless steel orthodontic wires in different artificial saliva and in different time periods. Materials and Methods: This study included six different commercial stainless steel orthodontic wires with different diameters. They were immersed i...
