Two dental [upper and lowerincisor inclination {the angle formed between the longaxis of the upper central incisor (U1) and the palatal plane(PP) and the angle formed between the long axis of the lowercentral incisor (L1) and the mandibular plane (MP)}] and threesoft tissue [nasolabial (nla), labiomental (lma) and soft tissuefacial convexity (n–sn–pog)] angular measurements wereanalyzed. The results showed no significant difference betweenmales and females concerning the proclination of upperanterior teeth and the prominency of upper lip, while the femalesexhibited more proclined lower anterior teeth and moreprotrusive lower lip than males. The males tend to have moreconvex facial profile than females
