Revascularization in an immature necrotic permanent incisor after severe intrusive luxation injury: a case report

Authors:

ABSTRACT

Background

Pulp necrosis as a result of trauma is common in almost all intruded teeth, and the ideal treatment method
for intruded immature and necrotic teeth has not yet been determined. Therefore, the aim of this report was to present a case of pulp
revascularisation in a severely intruded immature maxillary right incisor.

Case report

After clinical and radiographic examination,
the incisor was defined as necrotic. Revascularisation therapy was performed over multiple appointments. After 21 months of recall
appointments, healing of the periapical area and apical closure were seen to be complete. However, at the 27-month appointment, the
vitality tests were negative and revascularisation of the right incisor, which had intrusion injuries, had not occurred. The tooth underwent
root canal treatment. Finally, the tooth spontaneously erupted into the vestibule and was repositioned with orthodontic appliances.

Conclusion

Although revascularisation can promote continued root development and root dentin apposition, long-term root canal
treatment may be required due to treatment results with periapical inflammation in intruded teeth with open apices.
