We describe a rare case of "dens in dente" in an accessory germ in central location of an anencephalic phoetus. Its characteristics of having enamel surrounding normal dentin and normal pulpar cavity, all of them surrounded by the unaffected accessory germ leads us to describe the term "dente in dente". Such alteration is not previously described.
我们描述了一例无脑儿胎儿中央位置附属牙胚中罕见的“牙中牙”病例。其特征为正常牙本质和正常牙髓腔被牙釉质包绕,所有这些又被未受影响的附属牙胚包绕,这使我们提出“牙中牙”这一术语。此前未曾描述过这种改变。
