[Estimating facial asymmetries in individuals with malocclusion and normocclusion].

BACKGROUND

The en face photographs taken in standard conditions were used to examine the facial symmetry in examinees with normocclusion and malocclusion.

METHODS

A total of 80 examinees were included in the study (40 of whom had normocclusion and another 40 had malocclusion) without any prior orthodontic therapy. The face was divided into six squares by the mediosagittal line drawn through the Trihion, Glabella, Subnasals and Gnathion as well as by horizontal lines drawn through the same points. The four lower squares - the middle and the lower thirds of the face were taken into account to analyse facial symmetry. The symmetry between individual squares was measured by applying transparent paper with a millimetre-sized squares web and a planimetry.

RESULTS

The results did not show any asymmetry between left and right parts of the face in either group of examinees.

CONCLUSIONS

A high correlation was established among all the analysed variables.
