Two Cases of Mesiodens in Nasal Cavity / 대한이비인후과학회지

ABSTRACT

Supernumerary teeth, which is described as teeth or tooth substance that develops in excess of deciduous and permanent teeth, most commonly involve the anterior maxilla. Mesiodens are one type of supernumerary teeth that develops in paramedian space of premaxilla. Sometimes mesiodens can be inverted with its crown facing the nasal cavity. Because of its own pathology and possible disruption of neighboring normal teeth, supernumerary teeth should be removed regardless of its eruption. We experienced two cases of mesiodens detected in the nasal floor and so report these cases with a review of literature.
