A condition characterized by red, painful, glazed, and friable gingivae. It may be a manifestation of some muco-cutaneous conditions such as lichen planus or a vesiculo-bullous disorder such as pemphigoid. There is a loss of stippling and the gingiva may desquamate easily with minimal trauma (unlike plaque-induced gingivitis). It is more common in elderly females and affects mainly the buccal or labial gingiva. It does not respond well to traditional oral hygiene measures or conventional periodontal therapy alone.
