title: Clinical considerations for reattachment of tooth fragments.
abstract: Trauma to anterior teeth is relatively common among children and teenagers; it has been estimated that approximately one quarter of the population under the age of 18 years sustain traumatic injury in the form of anterior crown fracture. Reattachment of a fractured fragment to the remaining tooth can provide esthetically pleasing results provided that the fragment is available. In this report, a systematic clinical approach through evaluation of periodontal, endodontic, coronal, and occlusal aspects is presented to help dentists analyze the factors affecting selection of techniques and materials. In addition, use of adhesive materials for tooth fragment reattachment is illustrated. Modifications of the reattachment process, including placement of veneer and radicular post, are also discussed.
