✅ Introduction
Dentoalveolar trauma represents one of the most frequent pediatric dental emergencies, with an incidence peak in children aged 8 to 12 years. Injuries may affect the teeth, periodontal ligament, alveolar bone, and soft tissues. Proper management relies on accurate classification, immediate stabilization, and long-term monitoring to prevent complications such as pulp necrosis, ankylosis, or tooth loss.
1. Diagnosis and Initial Assessment
A systematic evaluation includes:
▪️ Trauma history: mechanism, timing, contamination.
▪️ Clinical examination: tooth mobility, displacement, soft-tissue injuries.
▪️ Radiographic assessment: periapical radiographs or occlusal views to detect fractures or displacement.
▪️ Assessment for non-accidental injury in very young children.
Key diagnostic criteria involve identifying the type of injury according to the International Association of Dental Traumatology (IADT) classification.

This article reviews the most common emergencies, including trauma, infections, and soft tissue injuries, offering an evidence-based guide for clinical management.2. Common Types of Dentoalveolar Trauma in Children
2.1. Concussion and Subluxation
➤ Features: Tenderness, mobility without displacement.
➤ Management: Occlusal relief if needed; soft diet for 7–10 days; periodic monitoring for pulp vitality.
2.2. Luxation Injuries
➤ Lateral luxation: Displacement with alveolar fracture; reposition and splint for 4 weeks.
➤ Extrusion: Gentle repositioning and flexible splinting for 2 weeks.
➤ Intrusion:
▪️ Primary teeth: allow spontaneous re-eruption.
▪️ Permanent teeth: spontaneous repositioning or orthodontic repositioning depending on root development.
2.3. Dental Avulsion
➤ Primary teeth: Replantation not recommended.
➤ Permanent teeth: Immediate replantation is the gold standard when feasible.
▪️ Transport medium: HBSS, milk, saline.
▪️ Splint: Flexible, 2 weeks.
▪️ Systemic antibiotics may be indicated (amoxicillin or doxycycline depending on age).
2.4. Crown and Root Fractures
➤ Uncomplicated fractures: Composite restoration.
➤ Complicated fractures: Pulp therapy based on stage of root development.
➤ Root fractures: Repositioning and 4-week splint.
2.5. Alveolar Process Fractures
➤ Repositioning of the segment and 4–6 week rigid splinting.

Follow-up intervals recommended by the IADT:
▪️ 1 week, 1 month, 3 months, 6 months, and 1 year, then annually for 5 years.
▪️ Pulp vitality monitoring: thermal, electric tests, and radiographs.
Early detection of pulp necrosis, pulp canal obliteration, or inflammatory root resorption is essential.

Dental avulsion consists of the total detachment of the tooth from the socket, as a consequence of a strong trauma that affects the oral cavity. Given this urgency, it is important to go to the dentist to be able to reimplant it.4. Prevention Strategies
▪️ Use of mouthguards during sports.
▪️ Parental education on safe home environments.
▪️ Management of behavioral conditions (e.g., ADHD) associated with higher trauma incidence.
📊 Comparative Table: Splint Options in Pediatric Dental Trauma
| Aspect | Advantages | Limitations |
|---|---|---|
| Flexible Splints | Promote periodontal healing; recommended by IADT | Not suitable for alveolar fractures requiring rigid fixation |
| Rigid Splints | Provide stability for alveolar process fractures | Higher risk of ankylosis and root resorption in teeth |
💬 Discussion
Management of dentoalveolar trauma requires prompt intervention, but treatment decisions must consider the child’s age, tooth type, root development, and prognosis. Evidence indicates that improper or delayed management increases risks of pulp necrosis, ankylosis, and tooth loss. The IADT 2020 guidelines emphasize minimally invasive approaches, flexible splints, and reduced use of antibiotics.
Interdisciplinary collaboration between pediatric dentists, endodontists, and radiologists improves long-term outcomes.

Effective management of pediatric dentoalveolar trauma relies on accurate diagnosis, timely stabilization, and evidence-based treatment protocols. Long-term follow-up is essential to prevent complications such as root resorption or pulp necrosis. Prevention strategies significantly reduce incidence and severity. Updated IADT guidelines remain the gold standard in clinical practice.
🔎 Recommendations
▪️ Use IADT-based classification for all trauma cases.
▪️ Prioritize minimally invasive repositioning techniques and flexible splints.
▪️ Avoid unnecessary replantation of primary teeth.
▪️ Provide written post-operative instructions to parents.
▪️ Schedule structured follow-ups for at least 12 months after injury.
