Methods: Standardized lateral cephalograms of 30 Filipino females were examined in the Department of Orthodontics of the University of the Philippines. The sample group met the following inclusion criteria: Filipino ethnicity; 18-35 years of age; Class I occlusion with minimal spacing or crowding; full complement of permanent teeth (third molars may or may not be present); acceptable facial profile and no previous orthodontic treatment. The diagram was scaled based on the anterior cranial base and upper anterior facial height. Then The X and Y coordinates of all the landmarks were calculated on the tracings, with the right, lower corner of the mesh diagram as the origin. For comparison between the caucasians and Filipinos’ norms, the size modification was applied. The mean proportionate locations of the cephalometric landmarks of the adult Filipino females were compared with Caucasians .The comparative analysis was accomplished by the superimposition of their normative diagrams at nasion. One sample t-test was used for statistical analysis.
Results: Comparative analysis of the craniofacial differences between the Filipino sample group versus the Caucasians was examined and significant differences were found.
Conclusions: It can be concluded that differences exist between the craniofacial morphology of the Filipino sample group and the Caucasians.The differences between craniofacial pattern of Filipino sample group and Caucasians is mainly due to primarily the higher positioning of sella in the cranium.
