Selenium uptake into teeth determined by fluorimetry.
Selenium concentrations in successive layers of bovine incisor enamel showed no concentration gradient and no increase with age. Selenium was taken upt into the continuously-growing rat incisor in proportion to the amount of selenium in the diet. A sensitive (approximately 1 ng Se) and relatively simple fluorimetric method for determining selenium in small amounts of hard tissues is presented.
