Foreign bodies found in the maxillary sinus are usually iatrogenic and include misplaced dental roots which occur during dental extraction or dental tools used during treatment. Many of the traumatic foreign bodies are broken pieces of glass or metal. However, it is a rarity in the literature for a tooth that has been misplaced in the maxillary sinus for an extended period of time in its original form to cause a traumatic problem.
We have recently experienced a case of traumatic dental misplacement causing symptomatic problems 16 years after misplacement. A summary of our findings in this case is presented in this paper.
