Summary
Dentists using cone-beam computed tomography (CBCT) must recognize unexpected pathologies like foreign bodies or airway anomalies. Diagnostic responsibility lies with the dentist, who may consult a radiologist if uncertain.
Area of Science:
- Dentistry
- Radiology
- Oral and Maxillofacial Surgery
Background:
- Cone-beam computed tomography (CBCT) is increasingly used in dentistry.
- Incidental findings of occult pathologies are common in CBCT scans.
- Understanding diagnostic responsibilities is crucial for patient care.
Purpose of the Study:
- To identify frequent occult pathologies discovered incidentally via CBCT.
- To clarify the diagnostic roles and responsibilities of dentists and radiographers.
- To provide an iconographical guide for recognizing these pathologies.
Main Methods:
- A narrative literature review was performed.
- Focused on occult pathologies commonly identified with CBCT.
- Included iconographical examples for each pathology category.
Main Results:
- Frequent incidental findings include foreign bodies, airway anomalies, and maxillofacial radio-opacities/translucencies.
- These pathologies can be unexpected and potentially serious.
- The diagnostic role of the dentist and radiographer was examined.
Conclusions:
- Dentists must be prepared to recognize frequent, serious head and neck pathologies found on CBCT.
- Diagnostic responsibility for these findings rests with the treating dentist.
- Consultation with a specialist radiologist is recommended if the dentist lacks confidence in diagnosis.
