Which statement best explains why subgingival calculus deposits often appear flattened?

Subgingival calculus sits in the periodontal pocket between the tooth surface and the pocket wall. The pressure from the pocket walls presses the deposit against the root surface, molding it into a thin, flat layer along the cementum. This constant confinement and contact with the tooth makes the calculus appear flattened rather than bulky. Demineralization changes mineral content but not shape, tissue coverage doesn’t inherently flatten deposits, and scaling is a removal process, not a cause of the flattened form.
