Abstract

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.
