Periodontal Diseases Flashcards
Erythematous gingiva in response to an antigen in a hypersensitivity type reaction is called what?
Plasma Cell Gingivitis or Allergic gingivostomatitis
*Can use oral leukoplakia like rxn on sides of tongue
What idiopathic condition may be due to open mouth breathing and appears as a localized erythema?
Localized Juvenile Spongiotic Gingival Hyperplasia (Wrights lesion)
Gingival epithelium that spontaneously sloughs or can be removed with minor manipulation is called what?
Desquamative Gingivitis
*CLINICAL diagnosis
What is the list of 5 differential diagnoses for Desquamative Gingivitis?
1-Lichen Planus (most likely. Solid band of lymphocytes)
2-Mucous membrane pemphigoid (hemidesmosomes are attacked, sub epithelium separation)
3-Pemphigus vulgaris (intraepithelial separation, attacks desmosomes)
4-Systemic lupus erythematosis
