title: Intranasal tooth: report of three cases.
abstract: Intranasal teeth are uncommon, with only a few reported cases in the past few decades. The clinical manifestations of an intranasal tooth are quite variable. Unilateral nasal obstruction is a common complaint, but even though nasal symptoms are present, an intranasal tooth can be an incidental finding during routine examination in patients without nasal discomfort. Although the diagnosis is not difficult to make, a complete workup that included radiological investigations is important before any surgery is attempted. Transnasal endoscopic surgical approaches have been described with no evidence of recurrence or complications in similar cases. Herein, three patients with an intranasal tooth are described, along with possible etiologies, potential complications, differential diagnoses and their treatments.
