Which statement regarding the relationship between cementum and enamel is false?

The statement that cementum overlapping enamel causes a periodontal pocket is inaccurate because the overlap of cementum over enamel does not inherently lead to the formation of a periodontal pocket. Periodontal pockets are primarily associated with periodontal disease and the loss of attachment due to the inflammatory process, not merely the relationship between cementum and enamel.

The relationship between cementum and enamel can be classified into distinct arrangements: enamel may meet cementum, may overlap it, or there may be a gap between the two. The arrangement that leaves a gap can indeed contribute to sensitivity or discomfort during dental procedures, particularly if instrumentation exposes the dentin. However, the physical overlap of cementum over enamel itself does not create a space that leads to pockets; it is the bone and supportive periodontal tissue loss, usually due to disease, that results in pocket formation.
