Abstract:
This paper presented illustrations of two different clinical cases that developed residual bone scars. The first case dealt with the evolution of a bone scar after surgical removal of a large cyst with a "thru-and-thru" defect, not an uncommon event. The second case showed a typical periradicular lucency associated with a nonvital pulp, which evolved into a bone scar after nonsurgical root canal therapy.
