Abstract : Ameloblastoma is a tumour of odontogenic origin that can occur on the mandible especially in the posterior region classified as a benign type of tumour. It can surface from the tooth germ ectodermal epithelium, Odontogenic cyst epithelium, stratified squamous epithelium as well as the enamel organ epithelium. Typically, it is the 2nd most common variant of all odontogenic tumours. They represent about 1% of all jaw tumours. Among the variants of ameloblastoma, Unicystic ameloblastoma is considered the least aggressive. Unicystic ameloblastoma also comprises subtypes namely - mural, luminal and intraluminal subtypes out of which the mural subtype is taken under review with special consideration.
