Fusarium Infection of the Maxillary Sinus as a Complication of Overfilling of Endodontic Treatment: A Case Report

Abstract

It is generally accepted that the successful root canal treatment mainly depends on the suitable cleaning, canal shaping and proper obstruction of root canals. Various complications can be encountered during and after root canal treatment depending on the causes of over instrumentation and then extrusion of gutta-percha through the apical foramina.[1] The fungus in root canals was first discovered by Grossman. He found fungus in 17% of the samples.[2] The main etiological agents of the fungus were found as Candida, Penicillium, Aspergillus and Fusarium.[3,4] When it is accepted that root canal isolates are positive, Fusarium is a very rare opportunistic fungal infection. Fusarium infections have been occasionally reported in immunocompromised hosts.[5] The purpose of this case is to report whether the endodontic treatment of the molar tooth is a risk factor for Fusarium development and foreign materials in the maxillary sinus is removed by the Caldwell-Luc procedure.
