RESUMO

The objective of this investigation was to evaluate, through panoramic radiographs, the mesiodistal axial inclination of the upper anterior teeth and lower cuspids at the beginning and at the end of orthodontic treatment. The experimental sample consisted of 40 patients (20 males and 20 females) treated orthodontically by the simplified standard edgewise technique without extractions. From each patient a panoramic radiography was taken at the beginning (T1) and at the end (T2) of treatment. The mean values of the mesiodistal axial inclination at T1 were compared with the mean values at T2 and both were compared to the mesiodistal axial inclination of a normal control sample. Results showed that the mesiodistal axial inclinations of the upper anterior teeth and the lower cuspids at the beginning of treatment were different from those observed in a normal occlusion in 50% of the evaluated teeth. However, the inclinations at the end of treatment, were, in most instances, consistent with the normal anatomical configuration. In addition, the panoramic radiographs proved to be an important tool for this purpose.
