On proximal surfaces near the cervical area, radiolucent saucer-shaped defects are called what?

• A. Root caries
• B. Cervical burnout
• C. Proximal caries
• D. Root lesions

Answer: (D)

Focus on what the radiograph is showing at the root area. A radiolucent, shallow, saucer-shaped defect on a proximal surface near the cervical region points to changes on the root surface itself, where cementum and dentin meet. This pattern is described as a root lesion, which denotes a lesion involving the root surface (often called root caries when it progresses on the root). Cervical burnout is an imaging artifact near the cementoenamel junction caused by beam geometry and density differences; it doesn’t represent true tissue destruction and doesn’t typically present as a well-defined saucer-shaped defect. Proximal caries usually involve the crown enamel and dentin rather than the exposed root surface in that cervical vicinity. So the term that best fits a radiolucent saucer-shaped defect on the proximal root area is a root lesion.
