Management of sports-related root fractures.

Fractures that occur midroot are most frequently missed in radiographs unless multiple exposures at different angles are used for diagnosis. Immediate treatment consists of reduction of the fracture with close apposition of segments and rigid splinting for 3 months. Because of the good potential for healing, root canal therapy is delayed until evidence of pulpal necrosis is confirmed. Healing is by hard tissue, connective tissue, bone, or a combination of these accompanied by obliteration of the root canal.
