title: A clinical report of the management of episodic idiopathic pruritus occurring during endodontic therapy.
abstract: BACKGROUND
  In endodontic practice, conditions may arise that are unexpected despite thorough preparation. The purpose of this case report was to describe how a condition of episodic idiopathic pruritus, which was undiscovered in the medical history taking, was managed without a loss of time.
  
  
  METHODS
  A 29-year-old woman presented to the graduate endodontic clinic for conventional endodontic treatment of tooth #30 and intravenous moderate sedation for dental phobia. Before the administration of intraoral local anesthetics or intravenous medications, the patient was unable to keep still because of itching. When questioned, the patient reported that she suffers from this condition fairly regularly. The patient reported that the itching could be initiated by stress or for no apparent reason. Intraoral local anesthesia was administered, intravenous access was attained, and an analgesic and antihistamine were given.
  
  
  RESULTS
  Two minutes after the administration of the antihistamine, the itching resolved, and the treatment was completed without further incident.
  
  
  CONCLUSIONS
  This case provides an example of how an unexpected incident of episodic idiopathic pruritus was managed via the intravenous route without a loss of scheduled appointment time.
