Differential Diagnosis

Dentoalveolar Injuries

• Dental fracture
• Dental subluxation
• Dental avulsion
• Bleeding dental socket

Odontogenic Infections

• Acute alveolar osteitis (dry socket)
• Acute necrotizing ulcerative gingivitis (trench mouth)
• Dental abscess
  • Periapical abscess
  • Periodontal abscess
• Ludwig's angina
• Pulpitis (dental caries)
• Pericoronitis
• Peritonsillar abscess (PTA)
• Retropharyngeal abscess
• Vincent's angina - tonsillitis and pharyngitis

Other

• Scurvy
• Gingival hyperplasia
  • Phenytoin
  • Cyclosporine
  • Nifedipine, Amlodipine
  • Leukemia

Extrusive Luxation

1. Reposition tooth
2. F/u within 24hr for stabilization
3. Temporizing measure: Periodontal pack in which tooth is bonded to its two neighboring teeth on both sides

Lateral Luxation

1. More extensive injury than extrusive luxation
   1. Associated with cracking or fracture of the surrounding alveolar bone
2. Treatment
   1. Attempt repositioning of tooth
   2. Apply temporary splinting with periodontal dressing
   3. F/u within 24hr for stabilization

Intrusive Luxation

1. Most serious because of significant damage to alveolar socket and periodontal ligament
2. Treatment
   1. Allow tooth to erupt on its own
