Caption: Antibiotic-stained tooth. Light micrograph of a longitudinal section through a human tooth, showng fluorescence (yellow) due to the antibiotic tetracycline. Tetracylines are broad-spectrum antibiotics used to treat bacterial infections. They bind with calcium and become deposited in growing bone and teeth, causing staining and fluorescence. For this reason, tetracyclines are not normally given to pregnant women or children under 12 years old. This section shows the effects of several distinct courses of tetracycline on a tooth, with bands of yellow fluorescence running through the dentine that forms the root of the tooth (lower frame). Magnification unknown.
