摘要

Analysis of the facial profile is required for diagnosis and treatment planning in orthodontics. The Mongoloid Chinese race tends to have a flat facial profile and a more prominent zygomatic arch. The aim of this study was to identify the facial profile of Chinese high school students at W.R. Supratman 1 and 2 in Medan by photometry. An analytical descriptive study with a cross-sectional design was applied. The sample was compromised of 100 high school students (50 males and 50 females). The results showed no differences in facial profile between males and females using the Graber method. The straight profile comprised the highest percentage of participants, which was 62% of males and 68% of females, and the convex profile was 20% of males and 16% of females. The concave profile comprised the lowest percentage, which was 18% of males and 16% of females (p = 0.811). The results of the Singh method showed that the straight profile comprised the highest percentage at 70% of males and 62% of females, whereas the convex profile comprised 14% of males and 16% of females. The concave profile had the lowest percentage, which was 14% of males and 16% of females (p = 0.676). We conclude that gender had no significant effect on facial profile in a group of Chinese high school students.
