Which Gingival Structure is Located Closest to the Alveolar Mucosa

Question

Which gingival structure is located closest to the alveolar mucosa?
A) Sulcular gingiva
B) Free gingiva
C) Attached gingiva
D) Free gingival groove
E) B and D

Accepted Answer

The attached gingiva lies immediately coronal to the alveolar mucosa.The mucogingival junction demarcates these to structures.While the attached gingiva is pink in color,the alveolar mucosa is reddened by the underlying blood vessels and thinness of the mucosal epithelium.The alveolar mucosa is further distinguished by its lack of stippling and movable tissue.
