Title: Cephalometric norms among a sample of Yamani adults
Author: Daer, Ammar A.; Abuaffan, Amal H.
Abstract: Background: Cephalometric norms are decisive in diagnosis and treatment planning which differ in morphological feature among different ethnic and racial group. The aim of this study was to establish the cephalometric standards for skeletal and dental relationships for Yemeni population. Material and methods: One hundred ninety-four Yemeni university students (105 females and 89 males) aged 18–25 years, were selected from dental students in Sana’a. All partici- pants had Class I occlusion with normal growth, facial symmetry, and no previous orthodontic, orthopedic or maxillofacial surgery treatment. A Lateral cephalometric X-ray film was taken from each selected students. Each film was traced and analyzed according to Harvold’s Cephalometric Analysis. Results: Statistical significant differences were reported among genders in the skeletal sagittal relations; SNB, ANB, SNPg and SNBa angles, whereas, SNA angle showed no significant differences. The skeletal vertical inclination also showed statistical significant differences in ML-NL, NL-NSL, ML-NSL and Gn-tgo-Ar variables. Yemeni males had statistically significant higher upper and lower facial height than female and no significant difference between genders in the dental relationship variable except for the I-NB line which is statistically higher in female. Conclusion: The results of Yemeni cephalometric features showed ethnic differences in skeletal and dento alveolar relationship, sympathetic of the dento facial pattern of each population will ensure better results of treatment in ascertain optimal facial harmony. # 2016 Elsevier Ltd and the Japanese Orthodontic Society.
