A Systematic Study on Mitigating Parameter Variation in MOSFETs

Ectopic Supernumerary Nasal Tooth

“…1 Rhinitis, septal perforation and oronasal fistula have also been noted. 1 There are several conditions like Gardner"s syndrome characterized by multiple impacted supernumerary teeth, polyps of the large intestine, osteoma of the bones, multiple sebaceous cysts of the skin. 5 Cleidocranial dysostosis characterized by hyperplasia of the clavicle, delayed and defective dentition and many supernumerary teeth in maxilla and mandible.…”

“…Other proposed pathogenic factors include a genetic predisposition; developmental disturbances, such as a cleft palate; rhino genic or odontogenic infection; and displacement as a result of trauma or cysts. 1 The most common location is the upper central incisor area (mesiodens), followed by the maxillary third molar (peridens) and mandibular bicuspid areas 5 .The teeth may be asymptomatic or may cause nasal obstruction, facial pain, headache, epistaxis, foul-smelling rhinorrhoea, external nasal deformities, nasolacrimal duct obstruction. 1 Rhinitis, septal perforation and oronasal fistula have also been noted.…”

“…3 They have an atypical crown and they may be in a vertical, horizontal or inverted position. 1 We report a unique case of intranasal ectopic tooth eruption into the nasal cavity which caused significant nasal symptoms in an otherwise healthy patient which was removed endoscopically.…”

“…Ectopic eruption of teeth into the nasal cavity is a rare phenomenon. 1 Nasal teeth are a rare form of supernumerary teeth. 1 The incidence of hyperdontia or supernumerary teeth affects 3% of the general population.…”
