Correct answer: C — Cementicles

Cementicles are small, calcified, spherical bodies found within or on the surface of cementum or within the PDL. They may be attached to the root surface or free-floating within the PDL. During scaling, they can be mistaken for calculus deposits. Unlike calculus (which is mineralised plaque on the external root surface), cementicles are developmental/dystrophic calcifications within or beneath the cementum. They are generally incidental findings and do not require treatment, but their presence can complicate scaling and root planing.
