Foreign body in the maxillary sinus – a case report

Abstract

Contemporary dental treatment primarily aims at the longest preservation of the patient’s own dentition, provision of the proper function of chewing, as well as aesthetic requirements. According to literature, the percentage of successful endodontic treatment is particularly high and ranges from 92-98%. One of the most frequent complications of the endodontic treatment is overfilling of the root canal. Sometimes endodontic material penetrates to the maxillary sinus or to the mandibular canal. Here we describe a case of gigantic extrusion of endodontic material into the right maxillary sinus detected by means of a CBCT examination. Gigantic root canal overfilling can be precisely diagnosed by means of a CBCT scanning with lower effective patient dose than CT. The presented case underlines that attention must be paid to the amount of endodontic obturation material used during filling of root canals in order to prevent gross overfilling with potential extrusion of sealer to maxillary sinus.
