The Egyptian, Iranian, Iraqi and Ukrainian students occlusion dependence on dominant extremity and gender

Abstract

According to our results received the real dexters had only orthognathic and prognathic occlusions. Orthogenic occlusion was dominant in the real sinisters. The hidden sinisters did not have any physiological occlusion types but had biprognathic and deep occlusion in the equal correlation. The unreal sinisters had orthognathic, prognathic and biprognathic occlusions. The ambidexters did not have occlusion physiological types but had a practically equal distribution in opisthognathic and crossing occlusion. Orthognathic occlusion was dominant in the Egyptian, Iranian and Iraqi students while deep occlusion - in the Ukrainian ones. Deep and orthog nathic occlusion were dominant in the guys and the progenic one was absent in them. Biprognathic occlusion was insignificantly dominant in the girls while the orthog nathic and the deep ones were absent in them.
