Lateral Cephalometric Norms for Adult Emirate according To Steiner analysis
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 5
Abstract
The ideaof this study was to determine the cephalometric norms of typical Emirateyoung adult with class I molar relationship and well-balanced face and to compare these norms with Caucasians cephalometric norms according to Steiner’s analysis. Lateral cephalometric of 71 Emirate adults (37males age 20-25) (34female age 20-25) were traced and digitized using Dolphin imaging software program according to Steiner’s analysis. Advance maxilla and retruded mandible observed in Emirates sample and showed greater mean and standard deviation in SNA and ANB angles (p<0.001) and less SNB angle than Caucasians. More proclination in upper and lower incisor teeth according to (U1/NA, L1/NA) angles observed in the sample, also the mean value of MP/SN was higher (P<0.001) showing more vertical growth and increase in lower facial height. Greater horizontal growth observed in Emirate sample according to average value ofSN/OP angle when compared to the Steiner values (P<0.001). There are some fundamental ethnic differences in the craniofacial and skeletal measurements between Emirates and Caucasians young adult and theses variations support the ideaof a single standard for facial aesthetics should not be applied and used to all racial and ethnic groups. The results of this study showed that the Emirates’ Maxilla was more protruded, whilethe mandible was more retruded than the standard group. Moreover both occlusal SN/OP and mandibular planes MP/SN were also higher.
