Teeth which erupt in the 1 month of postnatal life are known as "neonatal tooth." The incidence of these teeth ranges from 1:2000 to 1:3500 live births. Natal teeth are more common in mandibular central incisor region, followed by maxillary incisor region and mandibular canine region. The neonatal or natal teeth in the maxillary molar region are a rare occurrence. This article represents a rare case of the neonatal tooth with Langerhans cell histiocytosis.
出生后1个月内萌出的牙齿被称为“新生儿牙”。这些牙齿的发生率在每2000至3500例活产中有1例。诞生牙在下颌中切牙区域更为常见，其次是上颌切牙区域和下颌尖牙区域。上颌磨牙区域出现新生儿牙或诞生牙的情况较为罕见。本文报告了1例伴有朗格汉斯细胞组织细胞增多症的新生儿牙罕见病例。
