How are cementicles viewed radiographically?

Cementicles are small calcified structures associated with the cementum of teeth. Radiographically, they appear as round, radiopaque calcifications due to their mineral composition, which is denser than the surrounding tissues in the oral cavity. The radiopaque nature of cementicles allows them to be detected on dental radiographs as small, white dots or spots against the darker background of the periodontal ligament space or the alveolar bone.

Their distinct appearance helps dental professionals identify them while interpreting radiographs, allowing for accurate diagnosis and treatment planning. The other choices do not accurately describe cementicles, which is why they are not considered correct.
