Evaluation of cephalometric lip morphology in a Saudi sub population: A cross sectional study

Abstract

This cross-sectional study was done to evaluate linear and angular measurement of lip morphology in Saudi adults and their comparison with the norms. After taking their history and physical examination, the patients were referred for a lateral Cephalograph using Dolphin Imaging Software. Linear and angular measurements related to lip morphology were recorded. Significant differences were found in the lower lip to E line, upper and lower lip protrusion, upper and lower lip to S line and upper and lower lip thickness, nasolabial angle, Z angle, with Saudi males having more prominent, thicker lips than the Saudi females. Comparison with the norms revealed that both lips are prominent among Saudi males, while in females there is an increased prominence of the lower lip. Value of the lower lip to H line is increased in both genders, males have prominent and thicker upper lips compared to the females and the lower lip in both genders is more prominent compared to the norms.
