Ectopic teeth with disparate migration: A literature review and new case series

Abstract

Purpose Ectopic eruption can be defined as the emergence of a tooth in an abnormal location, where the tooth does not follow its typical eruption pathway. While ectopic eruption within the dentate region is well-documented in the literature, ectopic eruption in non-dentate regions is relatively rare. This study aimed to report 6 cases of ectopic teeth and present a systematic review of the English-language literature on ectopic teeth, emphasizing demographic characteristics, radiographic features, potential complications, and treatment options. Materials and Methods A literature search was conducted using the PubMed, Medline, Web of Science, and Cochrane databases. The demographic data and radiographic findings of patients presenting with ectopic teeth were recorded. Results The literature review yielded 61 cases of ectopic teeth, with patients ranging in age from 3 to 74 years. The findings from these previously reported cases demonstrated that the most common location for ectopic teeth was the maxillary sinus, which is consistent with this case series. The Pearson chi-square test was performed to evaluate the correlation between age and location of ectopic teeth, and the results were found to be statistically significant ( P <0.05). However, no statistically significant relationship was observed between sex and the location of ectopic teeth. Conclusion The distinct features of these cases warrant reporting. This study presents the first case of supernumerary teeth in the condyle without any associated pathosis. Another notable characteristic is the pre-eruptive resorption of 2 inverted supernumerary teeth ectopically located in the palate, which predisposes to sinus opacification.

Endoscopically assisted removal of ectopic teeth in the floor of the orbit. Case report and latest literature review

“…The intraoral approach is safer, with fewer complications, but with a smaller field of visión ( 8 ). In the case of ectopic teeth in the maxillary sinus, the most used approach is the Caldwell-Luc because an adequate field of vision is achieved through an osteotomy of the anterior wall of the maxillary sinus and the risk of complications is minimal ( 9 ).…”
