Eucalyptus oil is an essential oil commonly used as a solvent to remove old gutta-percha when performing endodontic re-treatment procedures. Although commonly used by dentists, evidence for its safety is lacking. This report outlines a previously undocumented case of a 44-year-old male who attended the Oral and Maxillofacial Surgery department with sudden onset facial swelling in response to extrusion of eucalyptus oil through the apex of a tooth during root canal re-treatment by his dentist. The management of this case is discussed and the important safety aspects with regard to the chemicals used in endodontic treatments are reviewed.
CPD/Clinical Relevance: This paper highlights that the risk of extrusion injury during endodontic treatment is not limited to the use of sodium hypochlorite but also to other chemicals such as, and in our case, eucalyptus oil.
Article
A 44-year-old male was referred to the Oral and Maxillofacial department on an acute basis with a history of a sudden onset of facial swelling. The swelling of the lower right cheek had appeared during root canal re-treatment of the lower right second premolar (LR5) by his general dental practitioner (GDP) earlier that morning. It had worsened over the following few hours. His medical history was unremarkable except for a penicillin allergy.
On discussion with the dentist, it was reported that, during the re-treatment, eucalyptus oil (EO) was used to help dissolve the gutta-percha (GP) root canal filling material, and that this was delivered using an irrigation syringe. Irrigation of the canal with EO had elicited immediate severe pain around the jaw, shortly followed by onset of swelling. It was concluded that this was due to an extrusion injury involving the EO. It was reported that no other irrigants were used. Treatment was discontinued and the tooth was temporized appropriately.
