The most important diseases or complications that may be contributed to by a radicular cyst are:
Respiratory system (J00-J99)
- Abscess (encapsulated collection of pus) of the maxillary sinus.
- Sinusitis maxillaris (maxillary sinusitis).
Eyes and eye appendages (H00-H59).
- Orbital involvement (involvement of the bony orbit) in abscess of the maxillary sinus.
Blood, hematopoietic organs – immune system (D50-D90).
- Scattering of pathogenic (pathological) germs by infected radicular cyst.
Skin and subcutaneous tissue (L00-L99)
- Extraoral (“outside the oral cavity“) fistulization.
Infectious and parasitic diseases (A00-B99).
- Scattering of pathogenic germs in the blood and lymphatic circulation.
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Abscess formation
- Infection of the cyst
- Ostitis of the jaw
Musculoskeletal system and connective tissue (M00-M99)
- Osteolysis (bone loss)
- Pathologic fracture (bone fracture that occurs without force in a diseased bone).
Neoplasms – tumor diseases (C00-D48).
- Rare: malignant (malignant) degeneration.
Psyche – nervous system (F00-F99; G00-G99).
- Pressure on adjacent nerves
