AIM AND BACKGROUND
The management of avulsed immature teeth poses a significant challenge to clinicians, as prolonged dry time before reimplantation may lead to replacement resorption or ankylosis.
CASE DESCRIPTION
Recent studies have shown promising results with the use of an intracanal proprietary pharmaceutical preparation, followed by sealing of the orifice with mineral trioxide aggregate (MTA). Angiography suggested the presence of vascularized tissue after 1 year, indicating successful regeneration of pulpal tissue in the radicular area.
CONCLUSION
Despite an unfavorable crown-root fracture leading to tooth extraction after 9 months, histological examination revealed regular root dentin formation, indicating a favorable outcome.
CLINICAL SIGNIFICANCE
These findings offer hope for the management of avulsed immature teeth and underscore the importance of early intervention and appropriate treatment selection.

目的与背景
未成熟恒牙脱位的处理给临床医生带来了重大挑战，因为再植前过长的干燥时间可能导致替代性吸收或牙根粘连。
病例描述
近期研究表明，使用一种根管内专用药物制剂，随后用三氧化矿物凝聚体（MTA）封闭根管口，取得了令人满意的结果。血管造影显示1年后存在血管化组织，表明根尖区牙髓组织成功再生。
结论
尽管9个月后因冠根折导致牙齿拔除，但组织学检查显示牙根牙本质形成正常，提示预后良好。
临床意义
这些发现为未成熟恒牙脱位的处理带来了希望，并强调了早期干预和恰当治疗选择的重要性。
