Odontogennous Tumors

Ameloblastoma

Benign odontogenic epithelial neoplasm, it behaves as slowly growing expansion radiolucent tumor, occurs commonly in posterior regions of mandible has tendency of reoccur if not removed all. 80% in mandible at angle, adults mostly, unicystic or multilocular soap bubbles. Corticated margin homogenous radiolucency. Cortical expansion common, displace ttoth crown and resorb adjacent tooth roots, polycystic and peripheral invade surrounding structures Treatment:excision with margin

Adenomatoid Odontogenic Tumor

Benign epitheal odontogenic tumor appearing radiologically as well-circumscribed radiolucent/opaque lesion usually surrounding the crown of an impacted tooth in young adult/adolescent, characterised histology by columnar cell organised in a duct like configuration interspread with spindle-shaped cells and amyloid like depostion tht gradually undergoes dystrophic calcification, also called Ameloblastic adenomaroid tumor Unilocular well delineated margin, homogenous radioluceny but later calcified floccules. Cortical expansion maybe displace rather than reabsorb adjacent teeth

Ameloblastic Fibroma

Benign mixed odontogenic tumor characterised by neoplastic proliferation of both epitheal and mesenchymal components of tooth bud without the production of dental hard tissues, presents clinically as slow growing painless radioluceny, occurs most commonly in mandible of children and adolescent Unilocular/ crenulated/ multilocular, well-delinated and cortcateal homogenous radioluceny cortical expansion , displacement of tooth

Odontoma

tumor of odontogenic origin, hamartomatours composed of enamel, dentine and cementum and pulp tissue that may not be arranged in tooth form Compound- multiple small teeth denticle in a fibrous sac multiple small denticle on radiograph Complex- congeal irregular mass of dental hard tissue, intense capacity with radiolucent encapsulated

Calcifying Epitheal Odontogenic Tumor

Seen in adults and very rare, unilocular/crenulated/multilocular, well/poorly delinated margin, homogenous radioluceny initially, later calcified hoccules maybe cortical expansion may cause displacement/eruption

Ameloblastic Fibroma

Benign mixed odonotogenic tumor chaaracterised by neoplastic proliferation of both epithelial and mesechymal componets of the bud without the production of dental hard tissues, presents clinically as slow growing painless radioluceny, occurs most commonly in mandible of children or adolescent Unilocular/crenualted/multilocular wil delinated and corticated, homogenous radioluceny, cortical expansion (late) dsplacement of tooth

Ameloblastic Odontoma

Seen in midline of mandible multilocuted of mixed radioopaque/radiolucent content, demarcated calcified

Cementoblastoma

Benign odontogenic tumor of functiona;cementoblasts appears a mixed radiolucent/radioopaque lesion attached to a tooth root, a well dermacated
