Human typological aspects and maxillary-facial area asymmetry connections to mandibular fractures in HSEEU «UMCA» ukrainian students

Abstract

Asymmetry is maxillary-facial region feature which is expressed both under physiological and pathological conditions. Some literary data of Turkish dentists show higher level (approximately in 2 times and the difference is statistically significant) of traumatized permanent incisors among left-handers (13-17-yeared adolescents) than among right-handers. Left-handers had significantly higher risk on dental trauma. Unilateral clefts affinity has been confirmed for the left side, the proportion of left-sided clefts among left-handers are higher than that among right-handers. Another scientific work demonstrates handedness influence on ethmoid roof height.
