Keywords	Stainless Steel Crowns
Abstract	The study was undertaken to analyse in vitro biodegradation of stainless steel crowns, and space maintainers (stainless steel band materials) by keeping the respective number of samples in the artificial saliva incubating at 37°C. Nickel and chromium release after 1,7,14,21 and 28 days was analysed by using atomic absorption spectrophotometer. Results showed that there was statistically significant release of both nickel and chromium which reached maximum level at the end of 7 days and gradually reduced thereafter. The maximum release of nickel and chromium was much below than the dietary intake even for four crownsjband used and are not capable of causing any toxicity.
