keratinized gingiva
The portion of gum tissue that is tough and resistant to mechanical trauma due to surface keratinization.
Full Definition
Keratinized gingiva is the band of firm, coral-pink gum tissue that surrounds the teeth and resists mechanical forces during chewing and oral hygiene procedures. It extends from the free gingival margin to the mucogingival junction. Adequate keratinized tissue width is important for periodontal health and successful implant outcomes. Surgical procedures like free gingival grafts can increase keratinized tissue when insufficient amounts are present.
Usage
Usage note: Distinguish from 'free gingiva' which refers specifically to the unattached marginal portion.
