Manage- ment involves identification of the same, removal of any foreign body from the maxillary sinus, if present, followed by appropriate flap for closer. A case is presented when a gutta percha (GP) point was accidentally dislodged into the right maxillary sinus during preliminary diagnosis of the oro-antral fistula. The surgical management of the case is described and is the appropriate treat- ment plan. Keywords Gutta Percha, Maxillary Sinus, Caldwell-Luc Approach, Buccal Pad of Fat 1. Introduction The oro-antral communication is a well-documented postoperative complication associated with the extraction of maxillary molar and premolar teeth. Foreign bodies can get into the maxillary sinus mainly due to trauma and accidents during dental or surgical treatment (iatrogenic). The reason why most foreign bodies lodge into the maxillary sinus at the dental office is because the bone of the maxillary sinus floor is very thin and in some per- sons the roots of the molars project through this bone. The scientific literature reveals that among the foreign bodies found in the maxillary sinus are dental burs, roots of teeth, amalgam, titanium implants, glass, impression dental materials and, bullets and gutta-percha points. Less found bodies include stones, matchsticks, wood and many others. We report a case of accidental entry of gutta percha point in maxillary sinus that was retrieved through Caldwell-Luc approach and incision was done by buccal fat of pad. The approach is also used for re- trieval of maxillary teeth roots which get displaced in sinus and for management of maxillary sinusitis. * Corresponding author.
