Treatment Protocol for Retrieval of Tooth/Root Fragment Displaced in Maxillary Sinus: Report of Two Cases

Maxillary sinus is the largest of the paranasal sinuses and occupies the body of maxilla. The inadvertent displacement of a tooth or tooth fragment, foreign bodies like root filling materials, piece of amalgam during extraction, dental implants, needles etc. may occur in the paranasal sinuses through a variety of traumatic and iatrogenic events. Although it is questionable whether such a mishap should be regarded as a dental emergency; it is none the less a complication which should be treated without undue delay. This paper presents a report of two cases in which conservative treatment modalities have been performed and a step wise treatment protocol for the same has been discussed.
