Summary
This case report details successful treatment of a severe immature tooth fracture using mineral trioxide aggregate (MTA) for an apical plug. Two years post-treatment, the tooth remained asymptomatic with complete radiographic healing of the apical lesion.
Area of Science:
- Dentistry
- Endodontics
- Pediatric Dentistry
Background:
- Severe crown fractures in immature permanent teeth pose significant treatment challenges.
- Conventional endodontic treatment requires careful management to promote healing and preserve vitality.
- Mineral trioxide aggregate (MTA) is a biocompatible material used in regenerative endodontics.
Observation:
- A 12-year-old boy presented with a severe crown fracture of an immature mandibular permanent incisor.
- The tooth underwent conventional endodontic treatment followed by calcium hydroxide dressing.
- An apical plug was created using MTA to prevent material extrusion.
Findings:
- The patient remained clinically asymptomatic two years after the procedure.
- Radiographic examination revealed complete repair of the apical lesion.
- MTA apical plug effectively prevented gutta-percha and sealer overflow into periapical tissues.
Implications:
- MTA apical plugging is a viable technique for managing immature teeth with severe fractures and apical lesions.
- This approach facilitates successful endodontic treatment and promotes complete periapical tissue repair.
- Case reports like this contribute valuable clinical evidence for advanced endodontic procedures in pediatric dentistry.

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
