In addition to trauma, hard tissue obstructions such as cortical bone, nerve and vascular canals and supernumerary teeth, may prevent or divert root growth in impacted teeth. Provided the tooth is vital and apexification has not yet occurred, early treatment has the potential to offer space for further development in alveolar bone and to re-orient the cellular Hertwig’s sheath to grow normally, thereafter. Such treatment in traumatically-induced cases of arrested root development also has the capability to re-kindle root growth, where none existed previously. This holds out the promise of converting these severely compromised teeth and extraction-consigned teeth into useful elements of the adult dentition fair prognosis.
Evaluate whether root development of impacted teeth is adversely affected.
Demonstrate that early resolution of impaction can stimulate further root development.
Demonstrate that arrested root development due to trauma may be stimulated.
