title: Problems of root resorption in relation to orthodontic treatment planning: a report of three cases.
abstract: Three cases are described illustrating problems of root resorption related to orthodontic treatment. In the first case the short roots of many of the teeth made it inappropriate to carry out orthodontic treatment. In the second case there were no signs of root resorption initially, but, following retraction of maxillary incisors with a removable appliance, root resorption was noted affecting molar and premolar teeth, but not the maxillary incisors. In the third case several teeth had short roots, and further shortening of roots occurred during fixed appliance therapy. These cases illustrate the unpredictable nature of root resorption.
