Clinical case
A 49-year-old female Caucasian patient presented with recurrent complaints involving the left nasal cavity and suffering from a foul smelling discharge that had been unresponsive to medical treatment for the last 5 years. Her history excluded trauma or surgery and her family history contributed no useful information. The front teeth of the maxilla were clinically and radiographically normal. A panorama X-ray provided no clear details in the area of the nasal cavities.
Endoscopic inspection of
Review of the literature
A survey of the literature covering the period from 1 January 1959 to 1 January 2008 was conducted by two independent examiners focusing on SNTs. Owing to the relatively low specificity of the first-stage search strategy (Table 1) 1673 articles published in English were identified in PubMed (National Library of Medicine) and EMBASE (Ovid). The final selection comprised 25 well-documented cases of SNTs in 23 humans (Table 2). 20 cases reported one tooth, and in 2 cases there were two teeth. The
Discussion
SNT is a rare condition and the literature is restricted to case reports and case series only. Most SNTs are diagnosed in the third decade of life. The prevalence in the general population is unknown and the exact eruption time cannot be specified as SNTs may remain undiagnosed if they are asymptomatic in an arrested or subclinical state.
Regarding the origin of SNT, the frequently cited classical atavism theory3, which assumes the existence of a third dental lamina in the area of the front teeth

2021, International Journal of Surgery Case ReportsModified maxillary vestibular approach with subperiostal intranasal dissection for surgical extractions of mesiodentes impacted in the floor of the nasal cavity
2019, Journal of Cranio-Maxillofacial SurgeryCitation Excerpt :This approach is not indicated in the case of teeth erupted through the mucosa into the nose. In these cases endoscopically assisted transnasal extraction is preferred (Al Dhafeeri et al., 2014;Krishnan et al., 2013;Kirmeier et al., 2009;Lee, 2006; Sanei-Moghaddam et al., 2009;Clementini et al., 2012;Tang and Reisacher, 2014). Some authors use this endoscopic method for extraction of mesiodentes impacted right under the nasal mucosa as well (Krishnan et al., 2013;Clementini et al., 2012).

2014, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :In the latter theory, the crowded complete dentition triggers hyperactive proliferation of the epithelial remnants of the dental lamina near a permanent tooth bud, which leads to formation of an additional tooth bud.1,5 The spatial orientation of SNT is variable, and it has been proposed that they are a special case of mesiodentes that are inverted and thereby erupt into the floor of the nasal cavity.4 The cause of SNT is unclear, but proposed theories include obstruction at the time of tooth eruption owing to crowded dentition, exceptionally dense bone, genetic predisposition, developmental abnormalities such as cleft palate, rhinogenic or odontogenic infection, or displacement from trauma or cyst.6
Endoscopic removal of bilateral supernumerary intranasal teeth
2012, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :Therefore we investigated supernumerary intranasal teeth in the English-language literature. The review of Kirmeier et al4 between January 1959 and January 2008 and our further investigation until July 20115 showed 26 well-documented cases of supernumerary intranasal teeth, including the present case and the case of Kirmeier et al. The age when the supernumerary intranasal teeth were diagnosed ranged from 6 to 61 years (mean, 25.8 ± 13.4 years).
