Abstract
Objectives: To determine cephalometric norms according to Steiner's analysis and to evaluate differences exists between Bangladeshi adult male and female. And also compare the mean difference between present study and established value of Steiner's norms.
Materials and Methods: The present study was carried out on 100 standardized lateral cephalometric radiographs. The subjects included 50 males and 50 females. The ages of the subjects ranged from 18 to 24 years with a mean age of 20 years. The criteria of selection were Class I incisor relationship without any crowding, no skeletal abnormality, and no previous orthodontic treatment. All cephalometric landmarks were located and determined and subsequently tracing had been done according to Steiner analysis.
Results: There was a significant difference between the genders on almost all values. Generally in Bangladeshi male, both the maxilla and mandible were positioned forward but the maxilla-mandibular relationship was similar and also almost similar with the Caucasian norms suggesting class I skeletal pattern. The values were consistently larger than the Steiner's established cephalometric norms.
Conclusion: This analysis may suggest that, craniofacial morphology of the Bangladeshi male using Steiner's analysis is different from Bangladeshi female. The values provided here would aid in the diagnosis and treatment planning of orthodontic/orthognathic patients of Bangladeshi adults.
