Internal resorption and calcific metamorphosis are two sequelae of pulpal necrosis after traumatic injuries like concussion and luxation injuries. After traumatic injury, the pulp may become completely necrosed followed by calcification of the entire root canal by the activity of odontoblastic cells. In some other cases, partial necrosis of the pulp tissue with overstimulation of odontoclastic cells and resorption of the root canal dentinal walls may happened. Commonly any of the cells become active and one of the sequelae may will continue. Rarely these two conditions will happen together. In this particular case report with simultaneous occurrence of these two conditions with symptomatic periapical abscess.
