Other Gingival Disorders
Hyperplasia of gingival tissues may occur without inflammation in response to various drugs, particularly the following:
Hyperplasia is characterized by diffuse, relatively avascular smooth or nodular enlargement of the gingiva, which may almost cover some teeth. The hypertrophied tissue can often be excised. If possible, substitutions are made for the offending drugs. Scrupulous oral hygiene may minimize recurrence.
Squamous cell carcinoma can also originate in the gingiva and spread to regional lymph nodes.
