[Developmental disorders of permanent teeth after injuries of their primary predecessors. A retrospective study].
The present study evaluated posttraumatic developmental disturbances of 74 permanent teeth in 30 children, who had been treated in our department between 1992-1996 following trauma to the deciduous dentition. The recall in early 2001 included a clinical and radiographic examination. 24 of the permanent teeth showed developmental disturbances following injuries to their primary predecessors. The most frequent malformations were enamel discoloration and enamel defects. Injuries to the primary teeth that caused the majority of developmental disturbances were intrusions and lateral luxations. These results clearly show that the odontogenesis of permanent teeth can be influenced by trauma to deciduous teeth. Therefore, follow-up examinations are highly recommended after injuries to the primary dentition.
