Abstract

Aim: The purpose of this study is to describe the facial morphology of a Colombian population with three-dimensional imaging; and comparing their facial morphology with the Caucasian to create a database for this ethnicity. Materials and Methods: The study included 170 subjects selected from the Valle University in Cali-Colombia; and 1346 Caucasian subjects selected from the Face-Base Data funded by the National Institute of Dental and Craniofacial Research. All images were taken on Natural Head Position and captured using a stereo-photogrammetric camera system (3dMDfaceTM); to obtain a three dimensional image of each patient. The subjects were between 19 to 31 years old, with a normal BMI, and no craniofacial deformities. All images were plotted and analyzed using the 3dMD Vultus software to calculate linear and angular measurements. Standard deviation and means were calculated for each measurement and analyzed using t-test for different samples. Results: The Hispanic population had wider eyes, more protruded upper and lower lips, wider face and mandibular width. Caucasian females had a more acute full profile, larger middle third and less protrusive lips. Understanding the facial morphology of different populations would help to establish a better diagnosis and treatment planning for each ethnicity.
