title: Selenium uptake into teeth determined by fluorimetry.
abstract: 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.
