Abstract

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.
