Examples include iron (black stain), iodine (black), copper (green), nickel (green) and cadmium (yellow-brown). [3] Antibiotics. Tetracycline and its derivatives are capable of intrinsic discoloration (discussed below). However other antibiotics may form insoluble complexes with calcium, iron and other elements that cause extrinsic staining. [11]
The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
Hemosiderin can be identified histologically with Perls' Prussian blue stain; iron in hemosiderin turns blue to black when exposed to potassium ferrocyanide. [6] In normal animals, hemosiderin deposits are small and commonly inapparent without special stains.
Section of liver stained with Perls Prussian blue, showing iron accumulations (blue) consistent with homozygous genetic hemochromatosis. Perls's method is used to indicate "non-heme" iron in tissues such as ferritin and hemosiderin, [6] the procedure does not stain iron that is bound to porphyrin forming heme such as hemoglobin and myoglobin.

Iron is a mineral that is crucial for optimal health and well-being. Found naturally in many foods and dietary supplements, it is a key component of hemoglobin, the part of red blood cells ...
The symptoms range from a minor nuisance to being disabling in their impact on eating, swallowing, and talking, and the severe forms can cause people to lose weight.

Additionally, excessive starchy foods (such as bread, pasta, and crackers), fruits and milk products consumed frequently can cause the growth of dental plaque and bacteria. [29] Therefore, a diet low in sugar and proper maintenance of oral hygiene is the best way to promote and maintain sound tooth structure for an individual.
Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
