Aim: To analyze the young male adult facial proile using standardized photographs and compare manual measuring procedures to the measuring procedures with the software Cef X (CDT). Methods: The sample consisted of 40 Brazilian Caucasian individuals, with an average age of 21.9 years, who possessed pleasant proiles, normal occlusion, and no history of previous orthodontic treatment. Colored photographs measuring 10cm x 15cm were taken in a standard way with the subject in natural head position. The photographs were measured manually, using dial caliper and a protractor, as well as using the Cef X (CDT) computer program. Thirty six facial variables were analyzed with linear, angular, and proportional measurements. Results: Manual and computerized measurement scores presented different statistics to 24 variables. In the computerized method only one measurement showed signiicant difference between the irst and the second measuring whereas in the manual method eight measurements presented differences. Conclusion: Considering that there were differences in manual and computerized measurements, one must use respective mean values for each type of measuring procedure. Both types of measurement are reliable although the computerized one is more accurate. Due to the convenience and swiftness of the computerized measuring, it is best recommended.
