摘要

No effort has been made to define nickel magnitude from stainless steel crowns in oral environment.Nickel ions released in sufficient quantities from nickel-containing alloys may induce nickelsensitization or elicit allergic contact dermatitis. In this work nickel ion release from stainless steelcrowns in artificial saliva at different days and pH has been investigated which is used in pediatricdentistry. Totally 120 stainless steel crowns for primary teeth were immersed to artificial saliva in thisstudy. Nickel in aqueous solutions was determined by square wave voltammetry, usingdimethylglyoxime as a complexion agent on mercury electrode. The study revealed that nickel ionrelease was decreased with increasing pH. Furthermore nickel releasing ratio was decreased in all timeperiods. Results showed that metal ions released in this experimental condition were well below thecritical value to induce allergy and below daily dietary intake level.
