Abstract
Ectopic eruption of tooth has been reported in the nasal septum, chin, palate, coronoid process and maxillary sinus in the literature. A tooth may erupt maxillary sinus and present with chronic sinusitis, mucosele and cyst formation. Obstruction the osteomeatal complex, formation of cyst in the maxillary sinus, obstruction of nasolacrimal canal leading to epiphora may occur because of the anatomic variation. There may be sinonasal symptoms of sinusitis, epiphora and pain. The diagnosis of this condition can be made radiologically. If it is symptomathic treatment of ectopic maxillary tooth with dentigerous cyst is surgical removal via a Caldwell-Luc procedure. Herein we present an original image of a dentigerous cyst containing premolar tooth in the maxillary sinus.
Highlights
Ectopic eruption of tooth has been reported in the nasal septum, chin, palate, coronoid process and maxillary sinus in the literature
A plain computed tomography (CT) scan of the paranasal sinuses was done by taking 3-mm coronal slices
During development any abnormal tissue interaction between these cells may result in ectopic tooth development and eruption to different places may occur
