Intentional replantation to the endodontic-periodontal disease associated with misplacement of a rubber band-like foreign body: A case report

The authors report a case of severe periodontal destruction and subsequent pulp necrosis. Intentional replantation was performed to treat and investigate of the cause of this idiopathic, rapidly progressive, endodontic-periodontal lesion. A rubber band-like foreign body was incidentally discovered in the periodontal tissue. Although dislocation of a foreign body during dental treatment is unusual, it may happen occasionally. Careful oral examination is recommended, and a fissure-like deep crease in the free gingiva may be helpful in diagnosing misplacement of a foreign body in the periodontal tissue.
