运用扫描电子显微镜，对４枚禄丰古猿牙齿（恒齿）的釉质结构进行了观察研究。发现：禄丰古猿牙齿釉质表面有明显的釉面横纹结构；釉面横纹的密度向牙颈方向逐渐增大；观察记数了４枚牙齿的釉面横纹数，进而推算出牙冠的形成时间和年龄。与化石人科成员、现代人及现生大猿比较，禄丰古猿牙冠发育模式及时间，与南方古猿纤细种比较接近或相似，明显长于南方古猿粗壮种，有别于现生大猿
The scanning electron microscope (SEM) was used to observe the enamel structure of four Lufeng ancient ape teeth (permanent teeth). It is found that the surface morphology of Lufeng ancient ape tooth enamel has obvious glazed horizontal stripes structure; the density of horizontal stripes of glaze increases gradually to the direction of cervical teeth; the number of glazed stripes of 4 teeth is observed and counted, Crown formation time and age. Compared with the members of the fossil families, the modern people and the great ape, the development pattern and time of the Lupengao ape crown are similar or similar to those of the southern ape species, which are obviously longer than that of the southern ape Great ape
