title: The Differential Diagnosis of Desquamative Gingivitis: Review of the Literature and Clinical Guide for Dental Undergraduates.
abstract: BACKGROUND
  Desquamative gingivitis is an elucidating term used to demonstrate epithelial desquamation, erythema, erosions, and/or vesiculobullous lesions of the gingiva. Detection and differentiation between conditions that manifest desquamative gingivitis have been almost a continuing problem for dental undergraduates. Several studies have described the association between desquamative gingivitis and other relevant conditions. This study aimed to review the current literature on desquamative gingivitis and to formulate a clinical guide for the differential diagnosis of desquamative gingivitis designated as a teaching aid tool for dental undergraduates.
  
  
  METHODS
  A search strategy based on the key words "desquamative gingivitis, guidelines, diagnosis, undergraduate, teaching" was performed in Medline and Google Scholar. Papers published between 1932 and December 2014 were scrutinized. Only articles that describe the terminology and classification of DG-associated disorders or the diagnostic procedures of DG were selected, then obtained in full text and analyzed.
  
  
  RESULTS
  47 studies were included and reviewed narratively.
  
  
  CONCLUSIONS
  The clinical signs and symptoms of desquamative gingivitis are insufficient to make a definitive diagnosis. We proposed a clinical flowchart aimed to help dental undergraduates achieving their goal in making an accurate and easy diagnosis. However, this guideline needs further evaluation.
