A case of horizontal mid-root fractured tooth.

-Clinical and radiographical observations for 10 years-

Abstract

For ten years clinical and radiographic obsavations of a tooth with horizontal mid-root fracture were continued. In this case, the antibiotics was administered immediately after traumatic injury. At one week after injury, the tooth was repositiond and fixed with adhesive composite resin.

At three weeks after injury, the tooth became sensitive to the chilled water, and then the pulp was extirpated. At the next appointment, root canal was filled with guttapercha points and root canal sealer. At ten years after injury, there is no radiographic chenge of supporting structures except for the exisstance of broad separation between two fragments. Moreover, no clinical change is observed and the tooth functions well.

It seems that the traumatized teeth which have a root fracture of middle third need necessarily to be extracted, even if pulp necrosis occurs.
