Simultaneous occurrence of compound odontoma and arrested root formation as developmental disturbances after maxillofacial trauma: a case report.

subject

description

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanent tooth germ which may disturb its development. The extent of the malformation depends on the developmental stage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factor for these abnormalities. Open surgical procedures can also potentially cause impaction and developmental disturbances. Several developmental alterations such as discolouration, hypoplasia, crown dilaceration, root angulation or dilaceration, sequestration of permanent tooth buds and disturbance in eruption have been reported in permanent teeth after trauma. However, odontoma-like malformations and partial or complete arrest of root formation are rare complications developed after trauma. This article presents a rare case with simultaneous occurrence of an odontoma-like malformation and complete and partial arrested root formations as the results of maxillofacial trauma. Almost all pediatric fractures must be managed with closed reduction as much as possible. However, if it is necessary to perform an open reduction, careful attention must be paid during placement of the osteosynthetic plates and screws; and tooth bud development must be followed periodically.
