Radiologic findings in aspergillosis of the maxillary sinus
Oral Surgery, Oral Medicine, and Oral Pathology
|September 1, 1986
Summary
Endodontic materials containing zinc oxide and paraformaldehyde can cause antral aspergillosis. This fungal infection of the maxillary sinus often presents with a distinct appearance on X-rays, linked to prior dental procedures.
Area of Science:
- Otolaryngology
- Endodontics
- Radiology
Background:
- Antral aspergillosis is increasingly linked to endodontic materials like Endomethasone, N2, and Riebler Material.
- These materials commonly contain zinc oxide and paraformaldehyde, potential triggers for fungal infections.
Purpose of the Study:
- To investigate the association between endodontic materials and antral aspergillosis.
- To describe the clinical, radiological, and etiological features of solitary antral aspergillosis.
Main Methods:
- Retrospective analysis of 34 patients diagnosed with antral aspergillosis.
- Review of radiological findings, patient history (especially endodontic therapy), and treatment outcomes.
Main Results:
- A pathognomonic radiological appearance was observed in 76% (26/34) of patients.
- All but one patient had a history of endodontic therapy, suggesting a strong link.
Conclusions:
- Endodontic materials containing zinc oxide and paraformaldehyde are a significant cause of antral aspergillosis.
- Early recognition of characteristic radiological signs is crucial for diagnosis and management.
