The term 'Epithelial Attachment' specifically refers to the junction between the epithelial tissue and the tooth structure, particularly at the base of the gingival sulcus. This attachment is crucial for maintaining the integrity of the periodontal apparatus and helps to secure the gingiva to the tooth. It creates a seal that prevents the invasion of bacteria and helps protect the underlying tissues from periodontal disease. The integrity of this attachment is vital for overall periodontal health, as any disruption can lead to conditions such as gingivitis or periodontitis.

The other choices, while related to dental anatomy, do not accurately define the role of the epithelial attachment as it is understood in periodontal health and anatomy. The attachment primarily refers to the relationship of the epithelial tissue to the tooth itself at the gingival margins.
