What term describes the epithelium attaching the gingivae directly to the surface of the tooth?

The term that describes the epithelium attaching the gingivae directly to the surface of the tooth is junctional epithelium. This specialized type of epithelium is crucial in establishing the periodontal attachment, forming a seal that plays a key role in the overall health of the periodontium.

Junctional epithelium is located at the base of the gingival sulcus, where it connects the gingiva to the enamel of the tooth. This attachment helps in protecting the underlying tooth structure and the supporting tissues from external irritants and bacterial invasion.

Understanding the function of junctional epithelium is essential for dental professionals, as it helps in assessing periodontal health and diagnosing conditions such as gingivitis or periodontitis, where this attachment may be compromised. The other terms refer to different types of epithelial tissues that serve distinct functions in the mouth, but none specifically describes the structure anchoring the gingiva to the tooth surface as accurately as junctional epithelium does.
