Cephalometric norms of young adults of Bangladesh (Steiner’s analysis)- preliminary report
2013
Cephalometric radiography is the most significant tool for improving taxonomy, communication and analysis of dentofacial variation, as in orthodontic evaluation and treatment, analysis of
craniofacialmorphology is essential. Steiner's analysis was used in this study; because its methods of assessing skeletal and dental morphology are very useful and valid providing maximal clinical information with the least number of measurements. The objective of this study was to describe the
craniofacialpattern of
Bangladeshiyoung adults and to compare it with accepted standards for the Caucasian population according to Steiner analysis. The study will also evaluate morphological differences between male and female
Bangladeshinormal occlusion subjects. This is a cross-sectional observational study having both descriptive and analytical components. The study was conducted in Dhaka Dental College and Hospital on 52
Bangladeshiyoung adults (27male and 25 females), aged 21-27 years, having balanced harmonious facial profiles, clinically acceptable occlusion with permanent dentition and no history of orthodontic treatment. Lateral cephalometric radiographs of these subjects were used for a series of cephalometric analyses. All the measurements were
computed statistically. The study findings show that
Bangladeshisubjects were more protrusive skeletally and dentally than Caucasians with a greater tendency towards bimaxillary protrusion. Furthermore, the mandibular plane angle was smaller than that of the Caucasians, suggesting more prominent horizontal growth pattern in the
Bangladeshis. However, when the male and female
Bangladeshisubjects were compared, no significant differences were found in cephalometric
craniofacialparameters between both sexes. In view of the findings of this study, it is evident that there are some fundamental differences in the
craniofacialstructure between
Bangladeshisand the Caucasians. These differences should be kept in mind to facilitate better diagnosis, and orthodontic treatment for
Bangladeshipatients. The results of the present study support the idea that a single standard of facial esthetics should not be applied to all racial and ethnic groups. DOI: http://dx.doi.org/10.3329/bjodfo.v2i1.15997 Ban J
