Solitary Aspergillosis of Maxillary Sinus, a Complication of Dental Treatment

Aspergillus mycetoma of the Maxillary Sinus Secondary to Overfilling of a Root Canal

“…It has been suggested that root canal treated teeth with overextension of the root canal sealer into the sinus might be the main etiological factor for aspergillosis of the maxillary sinus in healthy patients (2,3). During obturation, the sinus may be invaded by either sealer or by solid materials such as gutta-percha (4) or silver cones.…”

Maxillary Sinusitis As a Complication of an Extruded Gutta-Percha: A Case Report

“…6 However, an accidental perforation of the schneiderian membrane during the root canal treatment or an intrusion of the obturation materials into the maxillary sinus may also cause sinusitis or aspergillosis. 12 In this case report, there was no alveolar bone between the apex of the roots and the sinus membrane; consequently the roots of the maxillary teeth were in the maxillar sinus. Besides, the poorly fitting master cone was extruded five millimeters into the sinus without even being realised.…”

“…Beck-Mannagetta et al 12 concluded that maxillary sinus aspergillosis was mostly caused by zinc oxide and formaldehyde including rootfilling materials. Moreover, Most cases concerning aspergillosis of the maxillary sinus were related to the overextended root canal sealer in the maxillary teeth.…”

Evaluation of the prevalence and specificities of asymptomatic paranasal sinus aspergillosis: Retrospective study of 59 cases

“…Various hypotheses have been proposed in the literature to explain the dental origin of sinus aspergillosis (marker of dental disease or predisposing to the development of sinus aspergillosis?) [4,10,11].…”
