Aim: Cephalometric analysis is a main part of diagnostics in orthodontics. Modern cephalometric analysis methods include using digital software or mobile applications. This study aimed to assess the validity and reliability of the CephNinjaPro application for linear and angular cephalometric measurements.Methods: In this cross-sectional study, 30 randomly selected lateral cephalograms were digitized by a digital scanner. The required landmarks for five linear and eight angular measurements were identified on all cephalograms using a fine tip pen by an experienced orthodontist, and then rescanned. To assess the validity of manual versus digital landmark identification using the CephNinjaPro application, the landmarks were identified on scanned cephalograms in both the CephNinjaPro application and Dolphin software. The results were compared before and after landmark identification. The results of the Dolphin software and the CephNinjaPro application were also compared before and after landmark identification. Data were analyzed using the paired t-test and Wilcoxon test.Results: The results showed significant differences in the angles SNA (P<0.001), SNB (P<0.001), inter-incisal (P=0.001), and MP-SN (P<0.001), and the Ga (P<0.001) between the Dolphin software and CephNinjaPro application before landmark identification. Also, significant differences were observed in the Ga (P<0.001) and SN-MP (P<0.001) angle between the Dolphin software and CephNinjaPro application after landmark identification.Conclusion: The CephNinjaPro application has acceptable validity and reliability for most of the linear and angular cephalometric measurements from the clinical perspective. Nonetheless, interpretation of results regarding some measurements should be done with caution.

Background: Evaluating patient’s soft tissue profile is one of the most imperative components for orthodontic diagnosis and treatment planning.
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.
