Sulcular Epithelium
Pronunciation: SUL-kyoo-lar ep-ih-THEE-lee-um
The non-keratinised epithelial lining of the peri-implant or periodontal sulcus, forming a crevice between the soft tissue and the implant or tooth surface.
Full Definition
Sulcular epithelium is the thin, non-keratinised stratified squamous epithelium that lines the gingival or peri-implant sulcus. Unlike junctional epithelium, it does not adhere directly to the implant or tooth surface but instead faces the sulcular space. In implant dentistry documentation, it is frequently referenced when describing the soft-tissue seal around the transmucosal component. Its integrity is considered important in preventing bacterial ingress that may lead to peri-implant disease. Editors must distinguish this term from junctional epithelium, which describes the adherent epithelial attachment at the base of the sulcus.
Usage
Usage note: The preferred clinical synonym is 'crevicular epithelium' in some peer-reviewed journals; editors should check house style and apply consistently throughout a document.
In Context
- "Histological examination revealed inflammatory infiltration of the sulcular epithelium consistent with early peri-implant mucositis." — Pathology report
- "The manuscript used 'sulcular epithelium' and 'crevicular epithelium' interchangeably; the editor standardized to the preferred journal term." — Manuscript editing note
