What is the result of apical migration of the epithelial attachment followed by atrophy of marginal gingiva?

The phenomenon of apical migration of the epithelial attachment combined with the atrophy of marginal gingiva leads to a specific condition in periodontal health. When the epithelial attachment moves apically, it signifies a detachment of the gingival tissue from the tooth surface, which can result in the exposure of more of the tooth root. Concurrently, atrophy of the marginal gingiva leads to a reduction in the height and contour of the gingival tissue.

This combination results in a periodontal pocket recession. In this context, "pocket" refers to the space that develops as the attachment apparatus shifts, and "recession" clearly indicates that the margin of the gingiva has moved further away from the crown of the tooth, exposing more root surface and possibly indicating periodontal disease. The health of the surrounding tissues is compromised, leading to this condition.

To clarify context, while other options refer to various forms of pocketing or gingival conditions, they do not accurately capture the specific impact of both apical migration and atrophy on the gingival margin as clearly as 'periodontal pocket recession' does.
