颏孔的形状、位置、方向、数目等,不仅在种系发生上有差异,而且在个体发生上因年龄的不同也有显著的变化,在种族上也有差异.因此对颏孔的形态研究,不仅在理论上而且在临床应用上均有一定意义.国内外学者曾作过一些观察与研究,但在例数、项目和各年龄组对比研究上尚感不足,为给解剖学、人类学和国人体质调查增添资料和为临床医学提供基础数据,我们分年龄组对下颌骨颏孔进行了观察和测量.
The shape, location, direction and number of mental foramen not only have differences in the occurrence of germ line, but also have significant changes in individual occurrence due to different ages, and there are also differences in race.Therefore, the morphological study of mental foramen not only Both in theory and in clinical practice have some significance.Chinese and foreign scholars have made some observations and research, but in the number of cases, projects and comparative analysis of each age group is still not enough, for the anatomy, anthropology and people Physical survey to add information and provide basic data for clinical medicine, we divided the age group mandibular mental foramen was observed and measured.
