摘要

我们提出了一个6岁和10个月大的男孩与阻生第一磨牙的情况。x线照片显示下颌右第一第二磨牙阻生，牙冠上有小硬组织作为障碍。我们取出小的硬组织和下颌右第一第二磨牙。组织病理学检查发现一个包含牙乳头、牙本质和牙釉质的牙胚。诊断为下颌右第二前磨牙的牙胚。因此，早期发现阻生乳牙对儿童的健康生长发育具有重要意义。

Impacted mandibular primary second molar: A case report

We present a case of 6-year- and 10-month-old boy with an impacted primary molar. An x-ray photograph revealed the impacted mandibular right primary second molar with small hard tissue on the crown of the tooth as an obstacle. We extracted the small hard tissue and the mandibular right primary second molar.

A histopathological examination of the obstacle revealed a tooth germ containing dental papilla, dentin, and enamel. The obstacle was diagnosed as the tooth germ of the mandibular right second premolar.

In conclusion, the early detection of impacted primary molars is important for children's healthy growth and development.
