由于龋病、外伤、畸形中央尖等因素导致牙髓感染、变性、坏死的年轻恒牙,严重者可能发展为根尖周炎,这将会影响年轻恒牙牙根正常的生长发育。在临床上,对于牙髓感染的年轻恒牙,传统的治疗方法包括根尖诱导成形术、根尖屏障术。近年来,学者们发现在牙根没有发育完全的年轻恒牙中,牙根端组织中存在着根尖周牙乳头干细胞,牙根生长形成与根尖周牙乳头干细胞的生物学功能有着密切的关系。介绍年轻恒牙髓感染治疗方法的新前景——牙髓血管再生术,并对其适应症、机制、治疗步骤作相关的阐述。
Due to dental caries, trauma, central deformity and other factors leading to pulp infection, degeneration and necrosis of young permanent teeth, severe cases may develop apical periodontitis, which will affect the normal growth of young permanent teeth root growth. Clinically, for the treatment of young permanent teeth infected with pulp, traditional methods of treatment include apexoplasty and apical barrier. In recent years, scholars found that there are apical papillary stem cells in the root tip tissue of young permanent tooth with incomplete root development. The root growth is closely related to the biological function of periapical papilla stem cells. To introduce the new prospect of treatment of young permanent pulp infection - pulp vascular revascularization, and its indications, mechanisms, treatment steps for related exposition.
