HOSA Dental Terminology Practice

Which of the following best describes the role of 'Epithelial Attachment'?

1. To assist in the formation of enamel

2. To support healthy gum tissue

3. To hold the gingiva to the tooth surface

4. To prevent cavities from forming

The correct answer is: To hold the gingiva to the tooth surface

Epithelial attachment is an important anatomical feature in dentistry that specifically refers to the connection between the gingiva (gum tissue) and the tooth surface. This attachment is formed by the junctional epithelium, which is a specialized epithelial tissue that creates a seal around the tooth, helping to maintain periodontal health. It plays a crucial role in anchoring the gums to the teeth, preventing the accumulation of bacteria and plaque in the sulcus, which can lead to periodontal disease. This attachment is vital for the overall integrity of the periodontal structures supporting the teeth. The health of the epithelial attachment is linked to the health of the periodontal ligament and other supporting structures, thereby making it essential for preventing gum disease. While other options might relate to aspects of oral health or the role of different tissues in the mouth, the primary and defining function of epithelial attachment is to secure the gingiva to the tooth surface.
