Evaluation of Integumental Extension Patterns in American-Japanese and its Comparisons to Burstone's Caucasian Standards

This research problem involved the evaluation of integumental extension patterns in American-Japanese and its comparison to Burstone's Caucasian standards to determine if measurable differences exist. From a sample of 15 males and 23 female American-Japanese, cephalometric headfilms were taken. Criteria for sample selection was similar to that established by Burstone. Cephalometric measurements of horizontal and vertical extensions were obtained according to Burstone’s method, The American-Japanese sample was statistically compared to the Caucasian sample by the calculation of the student t test. The results obtained showed significant differences between the males and females of the American-Japanese sample in eight of ten extension measurements. When comparing American-Japanese males to Caucasian males, four extension measurements were significantly different. In comparing American-Japanese females to Caucasian females, six extension measurements were statistically different. These measures which were statistically significant are, most probably, true differences in soft tissue extensions between the two racial groups.
