A longitudinal outcome study of lateral luxation injuries to the permanent maxillary incisors of children and adolescents

grantor: University of TorontoA longitudinal outcome study was undertaken to men variables that influence tooth survival, pulpal and periodontal outcomes of laterally luxated permanent maxillary incisors of children and adolescents. A sample of 42 patients (26 male and 16 female) with 58 laterally luxated incisors was identified. The mean age at the time of injury was 11.3 years (range. 6.3-17.8 years). Pulpal necrosis (PN) and pulp canal obliteration (PCO) were common healing complications. Cox and logistic regression analysis demonstrated that root development and extent of lateral luxation were not significantly related to PN and PCO ('p' > 0.05). This study represents the first to report incisor survival of children and adolescents following lateral luxations. In the entire sample (n = 58) no incisors were observed to fail. Therefore, parents can be informed that the survival prospects for laterally luxated incisors in children and adolescents are excellent.M.Sc
