Statement of problem Nickel is one of the most common causes of contact dermatitis and other numerous health hazards in children and so is a concern for parents as well as patients with stainless steel crowns. Even though Stainless steel crowns provide the best conservation of the teeth yet not enough efforts have been made to tackle Ni ion release from these alloys over time which may cause lymphocytic reactivity, periodontistis, respiratory diseases, chronic fatigue syndrome and possible carcinogenicity and other fatal outcomes leading to various major health issues in children. The incidence of nickel toxicity is more in females than in males. 1t's metallic look is another psychological trauma for the child when cemented on the anterior teeth along with parental dissatisfaction. Objective The objective of this in-vitro study is to measure the Ni ion release from Conventional preformed stainless steel crowns and compare with the Ni ion release from the stainless steel crowns coated with proprietary layer which may provide a possible solution to the Nickel ion release in children. Hypothesis It is hypothesized that stainless steel crowns coated with proprietary process have less Ni ion release than conventional stainless steel crowns.
