Calcium hydroxide effectively induced apical root development and periapical repair in a young patient with pulp necrosis and an incompletely formed root. This apexification treatment resolved the abscess and promoted significant root lengthening over 8 months.

Area of Science:

Endodontics
Regenerative Endodontics
Pediatric Dentistry

Background:

Dental trauma in children can lead to pulp necrosis and arrested root development.
Incomplete root formation presents challenges in endodontic treatment, particularly with associated periapical lesions.

Observation:

A 10-year-old male presented with an acute dentoalveolar abscess and a non-vital, immature tooth (tooth 11) with apical radiolucency.
Initial treatment involved urgent management of the abscess followed by chemo-mechanical debridement.

Findings:

Calcium hydroxide paste was used for apexification over 8 months, with regular changes.
Radiographic evaluation showed complete foramen closure, resolution of periapical radiolucency, and 5 mm of additional root development.
Long-term follow-up (3 years) confirmed normal periapical tissues and absence of symptoms.

Implications:

Calcium hydroxide apexification is a viable alternative to mineral trioxide aggregate or surgery for root-end closure in immature teeth.
This treatment can successfully induce apical root development and periapical healing in cases of pulp necrosis with periapical lesions.
Effective management of dental trauma sequelae in young patients is crucial for long-term dental health.
