and P.forsythus are all part of the "red complex," a specific
group of periodontopathogenic bacteria strongly associated with
severe forms of periodontal disease. Aggregatibacter

EndodonticsDiscoloration of teeth results from all the mentioned causes: 1) Decomposition of the pulp - breakdown products of hemoglobin and pulp proteins create dark pigments, 2) Filling materials - amalgam, silver points, and some sealers cause metallic discoloration, 3) Hemorrhage following pulp extirpation - blood breakdown products penetrate dentin tubules causing dark staining. Other causes include medications (tetracycline), fluorosis, aging, trauma, and certain foods/beverages. The type and cause of discoloration determines the most appropriate treatment approach.
