• May be associated with with incorporation of pigmented substance into plaques and accretions on teeth , rough pitted and decalcified surface of teeth, and remnants of enamel cuticle.
• It may be impossible to remove stains which have penetrated pits, fissure and porous areas of teeth.

• A black stain in the form of a fine line adjacent to the free gingival margin, which is not related to smoking, has been called metabolic stain and “mesenteric line”.
• This stain may occur as a broad thin black line following the contour of the free gingival margin onto the interproximal surface of the teeth

• Removal is sometimes more difficult because of pitting of the underlying enamel

Internal discoloration of teeth may occur as the result of decomposition of blood pigments associated with the death of the pulp.
