An ameloblastoma is a benign, yet locally aggressive odontogenic tumour. The vast majority (80%) of ameloblastomas arise in the mandible, and unicystic ameloblastomas are commonly found in relation to an unerupted lower third molar. We present the case of a 39-year-old patient with an incidental finding of an enlarged dental follicle around an unerupted lower third molar that progressed to an extensive unicystic ameloblastoma. This ameloblastoma was decompressed and marsupialized before enucleation to reduce the risk of pathological fracture due to the extensive size of the tumour. CPD/Clinical Relevance: The case is relevant to general dental practitioners when considering monitoring dental follicles of unerupted teeth because the enlarged dental follicle described progressed to an extensive odontogenic tumour.
AbstractSupernumerary teeth in the upper third molar region are relatively common but cases in the lower jaw are rare. In his survey of supernumerary teeth Stafne (1932) saw 131 upper but only 10 lower fourth molars. The following is a report of a single supernumerary tooth in the lower third molar region.
