The radiographic finding often mistaken for root caries due to its location is called?

• A. Proximal burnout
• B. Cervical burnout
• C. Occlusal burnout
• D. Facial burnout

Answer: (B)

Cervical burnout is a radiographic artifact that appears near the cementoenamel junction at the neck of the tooth. It happens because the cervical region has unique tissue thickness and dentin exposure, and the way X-rays are absorbed there can create a wedge-shaped radiolucent area. This radiolucency sits right where root surface caries would be suspected, so it’s easy to mistake it for decay. The distinction lies in its location and appearance: it is confined to the cervical area just apical to the CEJ and does not represent actual destruction of root dentin. Clinically, there is no surface breakdown or softening, and follow-up with clinical exam or different radiographic angles can confirm it’s an imaging artifact rather than real caries.
