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