A Cephalometric Analysis for Pakistani Adults Using Jarabak Bjork's Analysis

摘要

Objectives: The craniofacial characteristics of Pakistani adults were investigated in order to formulate cephalometric norms using Bjork-Jarabak's angular and linear measurements and to compare their mean differences with the established values of Bjork-Jarabak's cephalometric norms.Materials and Methods: The sample consisted of one hundred lateral cephalometric radiographs of Pakistani adults including males and females with age ranging from 18-25 years. The selection criteria were Class I incisor relationship with no crowding, no skeletal abnormality or deformity, and no previous history of orthodontic treatment. All the landmarks and analysis involved in Bjork analysis were located and tracings were done.Results: There is no significant difference among both the sexes except for anterior cranial base, Ramus height, Length of body of mandible, posterior facial height and the values of Pakistani adults were similar to Bjork standard values except articular angle and PFH/AFH ratio.Conclusion: The dentofacial pattern of Pakistani adults had slightly more prognathic mandible and a slightly horizontal growth pattern in comparison to Caucasians. This values obtained in the current study can be used as cephalometric norms for the Pakistani adults during diagnosis and orthodontic treatment.
