Alveolar Mucosa
The loosely attached, non-keratinised mucous membrane apical to the mucogingival junction that covers the alveolar bone.
Full Definition
Alveolar mucosa is the thin, mobile, non-keratinised tissue found apical to the mucogingival junction. Unlike the attached gingiva, it lacks a firm connective tissue attachment to the periosteum, giving it a redder, more friable appearance. Editors must distinguish it from attached gingiva and keratinised gingiva in clinical narratives. It is clinically significant when evaluating the adequacy of keratinised tissue around teeth and implants. Confusion with 'lining mucosa' is common in general dental texts.
Usage
Usage note: Always lower-cased except at the start of a sentence; do not hyphenate.
