2009

Materials used for dental impressions are usually safe. This study describes a case of fatal anaphylaxis that appeared immediately after the oral mucosa came into contact with an alginate paste used for dental impressions. The cadaveric examination and the poslmortem toxicology report confirmed that the cause of death was anaphylactic shock.
