Odontogenic Tumors Overview

A benign, locally aggressive tumor arising from epithelial remnants of the odontogenic apparatus.

A common type of ameloblastoma with a 'soap bubble' or 'honeycomb' appearance on X-rays.

A type of ameloblastoma with a single, well-defined radiolucency on X-rays.

The characteristic 'eggshell cracking' sound upon palpation, a sign of ameloblastoma's aggressive growth.

A type of ameloblastoma located within jaw bone, often causing bone expansion.

A type of ameloblastoma located on the surface of the jaw bone, less aggressive than its central counterpart.

A rare, benign odontogenic tumor with a radiolucent appearance, often found in the anterior maxilla.

A benign, calcifying tumor that is mostly asymptomatic, commonly found in the posterior mandible.

A developmental dental anomaly that resembles a tumor but is not, and is often seen in the first two decades of life, more commonly in the maxilla than the mandible. It is characterized by multiple radiopaque areas that resemble teeth, often in the anterior part of the mouth.

A developmental dental anomaly similar to a compound odontoma but with a more disorganized mass of enamel, dentin, and pulp. It lacks recognizable tooth shapes and appears as a single radiopaque mass surrounded by a thin radiolucent zone.

A radiographic characteristic of compound odontomas, where multiple radiopaque areas resembling teeth are visible.

A radiographic characteristic of complex odontomas, where a single, solid radiopaque mass is present, often with a surrounding radiolucent zone. This shows up on X-ray.

A developmental dental anomaly that shares characteristics of both ameloblastic fibroma and complex odontoma. It is found in young adults, primarily in the mandible, and often contains an impacted tooth.

A radiographic characteristic of ameloblastic fibro-odontomas, where a large, well-defined, mixed radiolucent/radiopaque area is visible.

The defining characteristic of ameloblastic fibromas, where strands and cords of epithelium resemble the development of teeth.

Characteristic of ameloblastic fibro-odontomas, where a capsule surrounds the lesion.

A type of ameloblastoma characterized by islands of epithelium surrounded by fibrous connective tissue. These islands have a central area with loosely arranged cells and an outer layer of columnar cells resembling ameloblasts.

A histologic variation of ameloblastoma where the central cells of the follicles undergo metaplasia to squamous cells, leading to keratin production in the center.

A histologic variation of ameloblastoma with central cells of the follicles appearing swollen and filled with eosinophilic granules.

A type of ameloblastoma where the epithelium proliferates in a mesh-like, interconnected network.

A variant of plexiform ameloblastoma where blood vessels rupture and extravasate red blood cells. This results in hemorrhage in the surrounding connective tissue.

A well-defined, benign, epithelial odontogenic tumor that originates from the reduced enamel epithelium. Less aggressive and treated conservatively.

A variant of ameloblastoma where the central cells of the follicles degenerate, forming microcysts. Multiple microcysts can coalesce to form large macrocysts.

A histologic variation of ameloblastoma where the ameloblast-like cells form a solid outer layer, and the central cells are stellate-like. Also known as Solid Ameloblastoma.

A benign, fibroblastic tumor originating from connective tissue of odontogenic origin, containing inactive odontogenic epithelium.

An aggressive dental tumor with a mucoid ground substance and mesenchymal cells.

A small, well-defined, radiolucent area on an X-ray with faint calcifications.

A type of odontogenic tumor with islands of polyhedral epithelial cells, hyaline eosinophilic material, and calcifications.

It can occur in the gingiva (peripheral) or in the bone (central).

This tumor typically affects younger individuals.

The peripheral type of odontogenic fibroma appears as focal growths on the gingiva, often with normal color or a reddish hue if ulcerated.

The central type of odontogenic fibroma usually presents as painless, slow-growing swellings in the mandible.

A rare, benign tumor composed entirely of dentin, often found in young individuals.

A type of osseous dysplasia affecting the cementum, usually presenting in middle-aged females.

A benign, well-defined mixed odontogenic tumor with epithelial and mesenchymal components.

A hamartomatous lesion found near unerupted teeth, composed of tooth-forming tissues like enamel, dentin, pulp, and cementum.

A tumor that originates from odontogenic (tooth-forming) tissues, involving both epithelial and connective tissue components.

A type of odontogenic tumor characterized by clusters of epithelial cells and a background of embryonic connective tissue.

Tumors that resemble normal teeth in shape (compound) or structure (complex), containing tooth tissues like enamel, dentin, pulp, and cementum.

A very dense, radiopaque mass of cementum appearing as multiple, often symmetrical lesions in the jawbone.

A benign, slow-growing tumor arising from odontogenic epithelium, commonly found in the anterior maxilla, often associated with impacted canines.

AOT typically appears as a well-defined, radiolucent lesion on X-rays, sometimes with small, faint radiopacities.

AOT is made up of tightly packed epithelial cells that are round or spindle-shaped, arranged in bands, tubules, or duct-like structures. An eosinophilic band is found at the periphery.

AOT is a locally aggressive tumor that can grow slowly but can also cause significant bone destruction if left untreated.

A locally aggressive odontogenic tumor that originates from epithelial rests in the dental lamina or reduced enamel epithelium.

CEOT can be found in the jawbone (central) or in the soft tissues of the mouth (peripheral).

CEOT presents as a slowly growing painless mass, often in the mandibular molar area. Peripheral CEOT appears as a soft tissue mass in the gingiva.

CEOT is considered locally aggressive and requires surgical intervention to prevent recurrence.
