The retrospective examination of 70 patients who had suffered fractures in tooth-bearing segments of the maxilla and the mandible when they were between one and twelve years old revealed a high incidence of late pathologic changes (in 39 out of 70). Disorders in odontogeny, eruption of the teeth and occlusion were observed. Primary and secondary loss of teeth did also occur. Our results show the necessity to inform both the young patients and their parents about the high incidence of late changes after jaw fractures in childhood. An effective recall-system is required in order to diagnose and treat such changes as soon as possible.
