title: An unusual cause of headache: a dentigerous cyst in the maxillary sinus.
abstract: We report the case of a patient with a dentigerous cyst in the maxillary sinus presenting as two months of intermittent, unilateral, pressure-like headaches. The diagnosis was suspected after an upright Waters' projection radiogram and confirmed histologically after surgical removal. The patient was symptom free one year later.
