Abstract：
Ectopic tooth in maxillary sinus is a rare entity. There are many causes of this condition include developmental disturbance, pathological process, iatrogenic, and in some cases there is no identified cause. The ectopic tooth could be asymptomatic or presented with various symptoms depends on its location. A 19-years-old woman presented with left-sided facial pain and slight swelling at the site of the upper 3rd molar tooth for three months. She gave a history of mid-facial trauma with an operation in this area, 11 years ago. Orthopantography and computerized tomography confirm the diagnosis of ectopic tooth within the maxillary sinus. The tooth was removed by Caldwell-Luc procedure. The patient was remained free of the presenting symptoms at three months follow-up. Reporting any case of an ectopic tooth deserves the ability to know the various aspects of this condition. We reported a further case of ectopic 3rd molar tooth in the left maxillary sinus, most probably, due to previous mid-facial trauma or the surgery in this area.
