# Gingiva is attached to tooth by:

A. Epithelial attachment

B. Periodontal Ligament

C. Connective tissue fibers

D. Lamina Propria

Answer: A, Epithelial Attachment

- Gingiva is attached to tooth by Junctional Epithelium which forms a collar around the tooth. It is wider (15-30 cells thick) at the floor of the gingival sulcus and tapers apically to a final thickness of some 3-4 cells. 

- Surface cells of the junctional epithelium provide the actual attachment of gingiva to tooth tissue (the epithelium being sometimes referred to as attachment epithelium)

- The internal basal lamina of Junctional epithelium unites the epithelium to tooth whereas the external basal lamina of junctional epithelium unites the epithelium to the connective tissue of the gingiva. 

- Basal lamina of junctional epithelium is devoid of type IV collagen and type VIII is present.
