Journal of Dentistry Indonesia

Objective: Stainless steel crowns (SSCs) are preformed metal crowns used to restore severely decayed primary teeth. The aim of this study is to evaluate the effects of pH changes and SSC margin trimming on nickel release in artificial saliva solution. Methods: A total of 90 SSCs were divided into three groups and placed in 35 ml of artificial saliva of pH 6.8, 5, and 3.5. Another group consisting 30 SSCs with trimmed margins was placed in saliva of pH 6.8. All SSCs were incubated at 37°C. The concentration of released nickel was assessed on days 1, 7, 14, 21, and …
