In clinical pediatric dentistry, dental professionals may encounter some dental abnormalities. It may progress in various ways; therefore, long-term follow-up is essential. We describe the case of a 5-month-old male, and how the mandibular incisor was lost due to trauma. He was referred to our hospital two days later, but the calcified tissue was detected in the oral cavity, confirming the residual tooth. We extracted the tooth, and a regular dental checkup revealed another residual tooth in the same region one year later. A residual tooth is considered to be affected by the Hertwig's epithelial sheath, and it may occur when the root is immature. It is important for dental professionals to share this information and to continue long-term follow-up when they encounter patients at young ages who have had such teeth extracted or lost due to trauma.
在临床儿童牙科中，牙科专业人员可能会遇到一些牙齿异常情况。其可能以多种方式发展；因此，长期随访至关重要。我们描述了一名5个月大男性的病例，以及下颌切牙因外伤脱落的情况。两天后他被转诊至我院，但在口腔中检测到钙化组织，证实存在残留牙。我们拔除了该牙齿，一年后的定期牙科检查显示同一区域又出现了一颗残留牙。残留牙被认为受赫特维希上皮根鞘影响，当牙根未成熟时可能会出现。对于牙科专业人员来说，当遇到因外伤拔除或脱落此类牙齿的年幼患者时，分享这些信息并继续进行长期随访非常重要。
