Prevention
- Timely root canal treatment of teeth with irreversible pulpitis before necrosis develops
- Proper working length determination to avoid apical extrusion
- Adequate coronal seal after root canal treatment to prevent reinfection
- Regular radiographic follow-up of root canal treated teeth (1 year, then 2-year intervals)
- Immediate management of acute dental trauma to prevent delayed necrosis
- Patient education about signs of spreading dental infection requiring emergency care
- Antibiotic prophylaxis considerations for immunocompromised patients
