A clinical, histologic and microradiographic investigation of 62 natal, neonatal and otherwise pre-erupted teeth from 51 children is presented. Such a comprehensive material has not previously been reviewed. Of the 62 teeth, 59 were mandibular incisors. A hereditary factor could be demonstrated in 12 cases. Fifty-three teeth showed more or less pronounced enamel hypoplasia. The enamel had a normal prism structure and mineralization with the exception of 22 cases where the prism structure was absent in the cervical part of the enamel. The cervical and apical dentin was atubular and in developing teeth the dentin in these regions changed to an irregularly formed hard tissue of osteodentin character, in which enclosed cells could be observed. Developing teeth often had no cementum, and in those cases where acellular cementum could be observed it was thinner than normal. In four patients atypically located carious lesions occurred.
本文对51名儿童的62颗出生时、新生儿期及其他萌出前牙齿进行了临床、组织学和显微放射学研究。此前尚未对如此全面的材料进行过综述。62颗牙齿中，59颗为下颌切牙。12例可证明存在遗传因素。53颗牙齿表现出或多或少明显的釉质发育不全。除22例釉质颈部无棱柱结构外，釉质具有正常的棱柱结构和矿化。颈部和根尖牙本质无小管，在发育中的牙齿中，这些区域的牙本质变为具有骨样牙本质特征的不规则形成的硬组织，其中可观察到包绕的细胞。发育中的牙齿通常无牙骨质，在可观察到无细胞牙骨质的情况下，其比正常情况薄。4例患者出现非典型位置的龋损。
