 Desquamative gingivitis involves lesions of the free and attached gingiva.Unlike plaque-induced inflammation of the gums (normal marginal gingivitis), desquamative gingivitis extends beyond the marginal gingiva, involving the full width of the gingiva and sometimes the alveolar mucosa.The term "full width gingivitis" usually refers to the oral lesions of orofacial granulomatosis however.
