ABSTRACT
ABSTRACT Objective Logistic regression method was used to establish a multiple regression sex discriminant function to discriminate the complete skull model and the incomplete skull model without frontal bone, occipital bone and mandible of Uygur adults in Turpan, Xinjiang. Methods A total of 117 ï¼60 male and 57 femaleï¼ three-dimensional skull models were collected by CT. Sixteen cranial measurement indexes were measured and calculated by computer software. The multivariate regression sex discriminant function was established with Logistic regression method and retrospectively tested. Results Among the 16 measurement indexes, except for nose width ï¼x7ï¼ and maximum frontal breadth ï¼x13ï¼, the remaining 14 indexes had statistical significance of differences between male and female ï¼P<0.05ï¼. For the discriminant function of complete skull established by eyebrow arch convexity ï¼x4ï¼, mastoid width ï¼x6ï¼, maximum cranial length ï¼x12ï¼, cranial base length ï¼x15ï¼, cranial circumference ï¼x16ï¼, the male and female discrimination accuracy was 90.0% and 94.7%, respectively. For the sex discriminant function of incomplete skull without frontal bone established by mandibular angle width ï¼x10ï¼, mandibular height ï¼x11ï¼ and cranial circumference ï¼x16ï¼, the discrimination accuracy of male and female was 85.0% and 84.2%, respectively. For the sex discriminant function of incomplete skull without occipital bone established by the index of eyebrow arch convexity ï¼x4ï¼, the discrimination accuracy of male and female was 80.0% and 73.7%, respectively. For the sex discriminant function of incomplete skull without mandible established by frontal chord ï¼x5ï¼ and occipital protrusion angle ï¼x9ï¼, the discrimination accuracy of male and female was 85.0% and 78.9%, respectively. Conclusion The computer software and system developed in our study can achieve sex discrimination of complete skulls and incomplete skulls without frontal bone, occipital bone or mandible.
