Body
Objective: Normal facial asymmetry which usually results from a small size difference between
the two sides is much more common than pathological asymmetry. The aim of this study is to
assess normal facial asymmetry of older than 18 year old class I patients in Iranian population.
Methods: In this descriptive- analytical study, 100 digital frontal view photographs of classI
occlusion patients older than 18 (50 males & 50 females) with the overjet of 3 mm or less
and the overbite of 1/3 tooth or less were evaluated. Ear rods of cephalostate were used for
fixing the head while taking the photographs. The distance between the midline and left &
right side of the face (ear rods)and between the midline and menton point was measured using
Photoshop software. Data was analyzed by an independent T test.
Results:The right side of the face in both males and females was larger than the left side
(63%). 54% of the patients had left side chin deviation. The difference between the size of
the right side of the face of males and females was significant( P= 0.039).
Conclusion: Normal facial asymmetry which exists in almost all normal individuals is due to
genetic and environmental factors.
