The<br>asymmetry in general was either functional and/or structural in nature. The objective<br>of this study was to investigate the relationship of the amount and direction of facial<br>asymmetry in clinically symmetrical faces with class I normal occlusion to<br>handedness, and to discover if there is any relation of occlusal bite force with<br>handedness and facial asymmetry in Iraqi Arab adult sample.<br>The sample was 60 untreated Iraqi adult persons, 30 right handers, 30 left handers<br>and each group consisted of 15 males and 15 females, with age range 18-25 years. For<br>each subject a posteroanterior radiograph was taken, and then a maximum molar bite<br>force was measured digitally in the first molar area on each side.<br>All subjects of the sample showed skeletal asymmetry although they have normal<br>occlusion and it was significantly greater in right handers than in left handers<br>(P<0.05).<br>Skeletal asymmetry was greater in males than females for both right and left<br>handers. In right-handers, the mean facial area on the left side was significantly<br>greater than that on the right side (P=0.000). In left handers, the mean facial area on<br>the right side was found to be significantly greater than that on the left side only in<br>females (P=0.004).<br>The bite force, in both right and left handed groups, was larger in males than in<br>females, with significant difference in right handers (P=0.03) and highly significant<br>difference in left handers (P=0.001).<br>Facial dimensions tend to be larger in males than in females. Skeletal asymmetry<br>was present even in clinically symmetrical faces with teeth in normal occlusion and it<br>was highly correlated to handedness. Bite force was independent of handedness with<br>significantly greater molar bite force in males than females.<br><br></p>}, number={2}, journal={Mustansiria Dental Journal}, author={Kadhim, Dr. Hayder A. and Saloom, Dr. Hayder F. and Ali, Dr. Suhad M.}, year={2018}, month={Mar.}, pages={190–200} }
