本文对108例汉族成人上颌及硬腭的五个径线进行了测量,并做了男女各项平均值性别差异的t值检验和性别判别分析。性差检验结果,上齿槽弓长和腭长的性差高度显著,其余各项目性差不显著。性别判别分析结果,7种不同判别式性别判定的正确率为61.11～74.07％,各个判别式的显著性检验结果均高度显著。最理想的判别式是由腭长、腭宽、腭高三个项目组合成的判别式,判别率为74.07％。上颌及硬腭径线对性别判定有一定意义。
In this paper, we measured the five radial lines of the maxillary and palatal palate in 108 Han Chinese adults and did t-value test and gender discriminant analysis on the gender differences of men and women. Sex difference test results, on the alveolar bow length and palate length of the significant difference between the height, the rest of the project was not significant difference. The results of gender discrimination analysis showed that the accuracy of gender discrimination of seven discriminant discriminants was 61.11-74.07%, and the significant test results of each discriminant were highly significant. The best discriminant is composed of palate length, palatal width, palate height of the three projects into the discriminant, the discriminant rate was 74.07%. The maxillary and palatal pathways have some significance on the sex determination.
