Fig. 2From: Clinical relevance of interdental papilla biopsy in chronic erosive gingivitis (desquamative gingivitis): retrospective bicentric study of 148 specimensClinical examples of systemic inflammatory and autoimmune diseases with predominantly gingival expression, diagnosed with the papillary biopsy technique. In all these patients, the gingiva was particularly inflammatory, hemorrhagic at the slightest touch and erosive in several places (clinical picture of desquamative gingivitis).
