Objectives: The purpose of this study was to determine the soft-tissue cephalometric standards for Yemeni adults.
Methods: The material composed of the lateral cephalometric radiographs of one hundred ninety-four Yemeni adults (105 females and 89 males) aged between 18 and 25 years, selected from dental students in Sana’a University. Each film was traced and analyzed using variable linear and angular measurement.
Results: Statistical significant differences were reported among genders in H- angle and N’-Pr-Pg’, whereas, N’-Sn-Pg’, nasolabial and mentolabial angles showed no significant differences.
Conclusions: The results of Yemeni cephalometric analyses showed ethnic differences in soft tissue findings. Considering the soft tissues pattern of each population will guarantee improved results of treatment to establish the best possible facial harmony.
