Unerupted incisors

Fifty consecutive cases presenting with unerupted maxillary incisors at orthodontic clinics were recorded and progress of the unerupted tooth followed up over a 4-year period following the exposure of the unerupted tooth (including removal of supernumerary tooth, etc., if present). The occlusal level, rotation, tilting, and general appearance were assessed at the conclusion of the investigation and the results are presented in this report. The earlier the removal of the causative factor preventing eruption of the incisor the better is the prognosis, and it is suggested that all teeth that have not erupted 6 months after the normal eruption date should be subject to radiological examination to ascertain any possible cause for the delayed eruption.
