Root displacement

(A) Large root fragment displaced into the maxillary sinus. The fragment should be removed by the Caldwell-Luc approach or sinus endoscopy. (B) The tooth in the maxillary sinus is the maxillary third molar that was displaced into the sinus during elevation of the tooth. This tooth must be removed from the sinus, potentially by the Caldwell-Luc approach.
