Sammanfattning

This study aimed to study frequency of sequelae in permanent teeth after luxation injuries to primary predecessors and to evaluate follow-up. Children 8 - 15 years (n=170) with luxation injury to primary dentition in 2003 were re-examined in 2010. Data from dental records and registration forms were analysed and tested by chi-square and t- test. Enamel defects were registered in 130 successor teeth, 22 % due to trauma, 21 % due to other aetiological factors (MIH, dental fluorosis, idiopathic). The proportions of successors with enamel defects were: after concussion 8 %; subluxation 18 %; lateral luxation 41 %; intrusion 38 % and avulsion 47 %. There were associations between enamel defects and the child's age and severity of the injury (P <0.05). Six children had enamel defects in successors of non-injured primary teeth. The clinicians did not always comply with the follow-up protocol. Minor luxation injuries and indirect trauma may cause enamel defects in permanent successors. Young age at the time of injury and dislocation of the primary tooth increases the probability of enamel defect in the permanent successor.
