- Abstract
Objectives: The objective of the study was to compare the Bangladeshi and Malaysian Chinese populations for old and recently developed sagittal cephalometric analyses. Study design: Cross sectional study involved lateral cephalometric radiographs of Bangladeshi and Malaysian Chinese population for sagittal assessment of maxillo-mandibular relationship. Materials and Methods: Pretreatment lateral cephalogram of 96 Malaysian Chinese orthodontic patients and 200 Bangladeshi patients were selected for the research. Radiographs were traced for angle ANB, Wits appraisal, Beta angle, W angle and Yen angle. Patients were divided into three skeletal classes i.e. I, II and III based on their cephalometric values, profile and incisor's classification from plaster models. ANOVA was applied to assess the difference in cephalometric values for all skeletal classes and independent-t test was used to compare the measurements for both the populations. Results: Skeletal class II was more prevalent in Malaysian Chinese sample and class I dominated the Bangladeshi sample. Mean values of all the measured analyses for all the skeletal classes were significantly different for both the population (p < 0.05) except ANB for class II and Yen angle for class III patients. Conclusions: All the performed analyses were significant in diagnosing the sagittal discrepancies. Bangladeshi and Malaysian Chinese populations are significantly different in craniofacial morphology; therefore the respective standards should be followed when diagnosis and treatment planning are formulated.
