Most of the intrinsic discoloration encountered in everyday practice is caused by the breakdown of blood products of the pulp tissue, due to trauma or a traumatic incident (Figure 7-7).This type of discoloration (ie, blood degradation) occurs during hemolysis, when iron is released from hemin, hemosiderin, hematin, and the addition of the bacterial product hydrogen sulfide, iron is converted to ferric sulfide, resulting in the discoloration of the dental enamel tends to change color either to orange, brown, or dark gray in color (Figure 7-8). In addition to blood product breakdown, the degradation of necrotic pulp tissue may also cause discoloration. Fortunately, most.
