title: Non-Inflammatory Destructive Periodontal Disease.
abstract: BACKGROUND
  Non-Inflammatory Destructive Periodontal Disease (NIDPD), is a severe destructive periodontal disease, that is characterized by the attachment loss and alveolar bone loss, without signs of the gingival inflammation, and the periodontal pocket development.
  
  
  OBJECTIVE
  Despite the fact that various cases of NIDPD have been reported; their etiology and disease evolution is still indefinite, and therefore, are open for discussion.
  
  
  METHODS
  An NIDPD case was studied in order to demonstrate features of the disease, and discuss the possible etiology and treatment.
  
  
  RESULTS
  In this clinical case, the etiology of NIDPD seems to be an association of endogenous opportunist bacteria with anatomical aspects, occlusion pattern, emotional stress and mouth breathing condition.
  
  
  CONCLUSIONS
  In spite of all cases described in the literature are comparable and may have similar etiology as related in this clinical case, additional research is needed to identify and clarify the role of the etiologic factors which determine the disease.
