摘要/Abstract

摘要：

牙外伤是儿童口腔常见疾病。单一类型的年轻恒牙外伤经过及时处理，牙齿甚至牙髓的存活率较高，但复杂牙外伤或者外伤牙根尖处有相邻的埋伏多生牙，则预后不确定性较高。本文报道1例上颌年轻恒中切牙根折合并根尖区埋伏多生牙的病例，在行多生牙拔除和牙髓血运重建术后，长期随访治疗效果较好。

关键词: 年轻恒中切牙, 根折, 多生牙, 牙根吸收, 牙髓血运重建

Abstract:

Dental trauma is a common oral condition in children. For single-type trauma to young permanent teeth, timely treatment often results in a high survival rate for both the teeth and the pulp. However, in cases of complex dental trauma or when supernumerary teeth are impacted near the apex of the injured tooth, the prognosis is less predictable. This article reports a case of root fracture in an immature maxillary permanent central incisor combined with impacted supernumerary tooth in the apical region. After supernumerary tooth extraction and pulp revascularization therapy, the case demonstrated a good treatment outcome over a nearly 10-year follow-up period.

Key words: immature permanent central incisor, root fracture, supernumerary tooth, root resorption, pulp revascularization
