BACKGROUND
External root resorption is a pathologic process starting from the root surface of the tooth. At present, there are few reports about the treatment of vital pulp preservation in the tooth with external root resorption.
CASE PRESENTATION
A 14-year-old Asian female visited the hospital of the present authors, complaining of the dentition was irregular. The results of CBCT revealed extensive ERR in the middle third of the root of tooth #16 and tooth #15 was impacted. After treatment, tooth #15 was removed, and the vital pulp of tooth #16 was preserved. The patient had no discomfort and was ready for future orthodontic treatment.
CONCLUSION
This paper reports the cases of extracorporeal resorption of tooth #16 caused by impacted tooth #15 combined with EMS and VTP during impacted tooth extraction. This report aimed to describe the causes of ERR and provide a viable potion to treat ERR in selected cases. Nevertheless, further clinical trials are needed for its long-term result.
背景
牙根外吸收是一种始于牙齿根面的病理过程。目前，关于保存牙根外吸收患牙活髓的治疗报道较少。
病例介绍
一名14岁亚洲女性因牙列不齐就诊于本文作者所在医院。CBCT结果显示16号牙牙根中1/3广泛牙根外吸收，15号牙埋伏阻生。治疗后，拔除15号牙，保留了16号牙的活髓。患者无不适，准备接受后续正畸治疗。
结论
本文报道了15号埋伏阻生牙导致16号牙体外吸收，在拔除埋伏阻生牙过程中联合牙髓血运重建术和活髓保存术的病例。本报告旨在描述牙根外吸收的病因，并为特定病例提供一种可行的治疗方案。然而，其长期效果仍需进一步的临床试验验证。
