Abstract:
Polyethylene glycol (PEG) is sometimes included in temporary endodontic filling materials to modify viscosity. PEG is considered a low hazard chemical, but parenteral PEG exposure is associated with a risk of anaphylaxis. We report 2 cases of anaphylaxis after treatment with an endodontic temporary filling material containing PEG. One patient survived after hospital treatment, but the second case was fatal. Extensive investigations were needed to find the culprit. Allergic reactions to PEG are increasingly reported and have significant implications for the patient. Precautionary measures are discussed.
