Ethical Dilemma: Incidental Finding on CBCT
A 35-year-old woman undergoes a CBCT scan for implant planning in the right posterior mandible. The scan reveals an incidental finding: a well-defined, corticated radiolucency in the left posterior maxilla, approximately 1.5 cm, suggestive of a cyst or benign tumor. The patient is asymptomatic. The clinician who ordered the scan is a general dentist and is unsure how to proceed. The patient is not aware of the finding. The clinician is concerned about alarming the patient and is unsure of the legal and ethical obligations.
1. What are the ethical and legal obligations regarding disclosure of incidental findings?
Read the worked answer
Ethical principles: beneficence (act in patient's best interest), non-maleficence (do no harm), and respect for autonomy (patient's right to know). Legal: duty to inform the patient of significant findings and refer appropriately. Incidental findings that are potentially serious should be disclosed. The clinician should not withhold information. The patient has a right to know about the finding to make informed decisions. The clinician should explain the finding in a non-alarming manner, provide context (many such findings are benign), and recommend further evaluation (e.g., referral to an oral and maxillofacial radiologist or surgeon). Documentation is essential.
2. What is the appropriate course of action for the clinician?
Read the worked answer
The clinician should: 1. Review the scan and confirm the finding, possibly consulting with a radiologist. 2. Inform the patient of the finding, explaining that it is likely benign but requires further assessment. 3. Refer the patient to an appropriate specialist (e.g., oral and maxillofacial surgeon or radiologist) for further imaging (e.g., CBCT of the maxilla, or biopsy) and management. 4. Document the finding, the discussion, and the referral in the patient's record. 5. Follow up to ensure the patient has acted on the referral. The clinician should not ignore the finding or delay disclosure. If the clinician is not comfortable managing the finding, referral is mandatory.
