Verification of maxillary and mandibular asymmetry via orthopantogram's analysis

Aim. The purpose of this study was to analyse the homologous variables' symmetry (horizontal, vertical, angular and of area surface) of the right and left segment in the maxilla and in the mandible of subjects with a normal occlusion and a malocclusion.
Methods. Two-hundred and two orthopantomograms were analysed (162 with malocclusion, 40 with normal occlusion). These points of reference were used: orbital, condilion, gonion, menton, point A (intersection point between the vertical line passing through the centre of the nasal septum and the horizontal line which links the 2 points O), point B (intersection point between the mandibular margin and the vertical line passing through point O) and point T (intersection point of A-Cn on the maxillary tuberosity).
Results. This study did not confirm any statistically significant differences between the right and left analysed variables studied in both groups.
Conclusion. Orthopantomography may be a useful test in the screening for facial asymmetry.
