Objectives: This project explores the demographic and clinical presentation of cemento-osseous dysplasia (COD), and their pathognomonic radiographic features. Methods: Demographic and clinical data were collected from the charts of 118 subjects with COD from the Oral Radiology archives. Using a systematic objective survey instrument, 3 general dentists (GP) and 3 oral radiologists (RG) reviewed 50 image sets of COD and similarly-appearing entities. Participants were asked to identify radiographic features and to make a diagnosis based on the images provided. Results: The majority of cases occurred in clinically asymptomatic females in their fifth decade. RGs identified a well-defined border, radiolucent periphery, bilateral occurrence, mixed radiolucent/radiopaque internal structure, and association with anterior and posterior teeth as key features, correctly interpreting 79.3% of COD cases. The absence of root resorption and an association with anterior and posterior teeth were the only key features that guided GPs to correctly interpret 38.7% of COD cases.
