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

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.

Multiple talon cusps and dens invaginatus associated with other dental anomalies - an unusual report

Talon cusp is a dental anomaly that occurs as an accessory cusp like structure from the cingulum of maxillary or mandibular anterior teeth. Dens invaginatus is a developmental variation which arises as a result of an invagination on the surface of a tooth crown before calcification has occurred. An unusual case of multiple talon cusps affecting the maxillary central incisors and the canines bilaterally together with other dental abnormalities viz dens invaginatus affecting the maxillary lateral incisors, microdontia, short roots, reduced alveolar bone height, dilaceration of the described posterior teeth, anterior open bite and bilateral posterior cross bite in a 35 year old male. The presence of these dental anomalies in a single patient is very rare and this is perhaps the first case report of this nature. None of these anomalies alone are particularly uncommon but they have not previously been reported together. The occurrence of these anomalies is probably incidental as the conditions are aetiologically unrelated and no developmental syndrome was identified
