The prenatal development of cheek-teeth of rabbits was studied by histological methods. Females from 15 to 30 days of gestation were sacrificed and their fetuses were collected and decapitated. The heads were fixed in buffered neutral formalin and paraffin embedded. Sagittal and frontal sections of 7 mu were obtained and stained with hematoxylin-eosin. The first tooth-germs observed were the m3 and m3, in the animal of 16 days of fetal life. One day after the m4 and m4 are observed in the bud stage. The last teeth to initiate development in the fetal rabbits are the M3 and M3 at 30 days. Only the m3, m4, m3 and m4 start cementogenesis in the prenatal stage.
采用组织学方法研究了兔颊齿的产前发育。处死妊娠15至30天的雌性兔子，收集其胎儿并断头。将头部固定在缓冲中性福尔马林中，然后进行石蜡包埋。获取7微米的矢状面和额状面切片，并用苏木精-伊红染色。在胎儿期16天的动物中观察到的第一对牙胚是m3和m3。在芽期观察到m4和m4一天后。胎儿兔中最后开始发育的牙齿是30天时的M3和M3。只有m3、m4、m3和m4在产前阶段开始牙骨质生成。
