— Single‐rooted premolar teeth, stained with blood utilizing the technique devised by Freccia & Peters (1981), were subjected to traditional and non‐peroxide bleaching agents. Colour changes were recorded over a period of 7 days using a Speedmaster R75‐CP Reflection Densitometer. The most efficient removal of staining occurred after the application of 30% hydrogen peroxide, with sodium perborate being 75% as effective. AU bleaching agents realized their optimum efficacy within the first 3 days. A combination of three enzymes (amylase, lipase and trypsin) with disodium edetate was not as effective as the routine bleaching agents; however, the combination did have a modifying effect on the blood stains. It is suggested that other non‐peroxide agents should be investigated to determine their efficacy in removing staining from experimentally induced blood‐stained teeth.
