Abstract
The present study was undertaken to evaluate the surface topography of mandibular natal and neonatal incisors at the ultrastructural level using the scanning electron microscope (SEM). The enamel of the teeth exhibited hypoplastic, depressed areas and the incisal edge of natal tooth lacked enamel. In addition, root formation of the teeth was not completed, which correlated with findings that teeth may erupt without root formation.
摘要
本研究旨在使用扫描电子显微镜（SEM）在超微结构水平评估下颌出生时即有的乳牙和新生恒牙的表面形貌。牙齿的牙釉质呈现发育不全、凹陷区域，出生时即有的牙齿切缘缺乏牙釉质。此外，牙齿的牙根形成未完成，这与牙齿可能在没有牙根形成的情况下萌出的研究结果相关。
