The term is now used to denote leasions that contain all the dental tissues and includes two types, the complex and the compound odontoma.[1] According to the. A case of compound odontomas of the anterior maxilla is discussed. Multiple tooth like structures were discovered upon surgical excision. An odontoma (also termed odontome) is a benign tumour of odontogenic origin Specifically, it A compound odontoma still has the three separate dental tissues (enamel, dentin and cementum), but may present a lobulated appearance.

An 8-year-old girl presented to her dentist for a routine dental examination. A panoramic radiograph shows a collection of tooth-like structures with a narrow radiolucent rim apical to the canine, lateral and central incisors in the right mandibula, as well as an impacted right maxillar premolar tooth. The treatment of choice for compound odontomas is surgical removal, followed by histopathological analysis to confirm the diagnosis [ 7 odontooma, 22 — 25 ].

The Journal of Craniofacial Surgery. Back to cited text no. The relationship is similar to that of normal teeth.

A case of compound odontomas of the anterior maxilla is discussed. Unknown; trauma, local infection, inheritance have been proposed.

Subdivided into compound odontoma and complex odontoma The most common odontogenic tumor Can obstruct the path of erupting teeth Most recent WHO Classification of Head and Neck Tumours regards majority of ameloblastic fibro-odontomas as developing odontomas rather than a distinct tumor IARC: The histological examination confirmed the clinical and radiographic diagnosis odintoma compound odontoma.

Periapical radiographs taken at the time of implant placement showed no signs of recurrence or complications at the surgical site Figure 9. The retained teeth were extracted and a full thickness mucoperiosteal flap was reflected. We present an interesting and a rare case of compound odontoma in the mandible of an adult patient.

A mucoperiosteal flap was etched and raised and bone was removed on vestibular side using a low-speed dental hand-drill and a tungsten carbide bur until the crown of the permanent impacted canine was exposed Figure 4. The case described in this report was initially diagnosed as compound odontoma based on the radiographic findings.

Cementum was sparse and seen in isolated distribution [ Figure 4 ]. Radio opaque lesion surrounded by radiolucent zone. Neither the patient nor her parents could recall any history of pain or swelling in the area.

It is composed of dentin, cementum, pulpal tissue and enamel. Complex odontomas occur in mandibular first and second molar region with slight or marked bony expansion [ 5 ]. The lesion was found on the anterior region of the maxilla, which, according to many researchers, is the most common location.

Odontoma – Wikipedia

For this reason, a double access was chosen, creating two small bone gaps with the use of low-speed dental hand-drill and a tungsten carbide co,pound to extract the components from two different small sites instead of a single large one. Images hosted on other servers: A second flap was performed on the vestibular side for the extraction of single structures of the odontoma Figure 7.


Shafer’s Textbook of Oral Pathology. Fibrous connective tissue with a cystic lining representing a dentigerous cyst may also be seen 15 — Despite this, odontomas are clinically considered as tumor-like odonttoma hamartomas of dental tissues or developmental anomalies, rather than true odontoms neoplasms [ 2 ].

Diagnostic Histopathology of Tumors: Odontomes must be surgically removed, in order to prevent cyst formation and possible conversion to odonto-ameloblastoma. On microscopic examination of hematoxylin and eosion H and E stain section, normal appearing enamel spaces, dentin and pulp tissue were seen, and they were exhibiting a regular relation to one another. Compound and complex odontomas. Introduction Odontoma is a benign odontogenic tumor.

Patient had maxillary protrusion and wanted orthodontic treatment for the same. Odontomw complex odontomas, all dental tissues are formed, but appeared without an organized structure. Currently, the treatment is underway and the teeth are being extruded and aligned orthodontically [Figure – 10]. Ghost cells are especially seen in complex odontoma Figure 8. The complex odontoma consists of a conglomerate mass of enamel and dentin, which bears no anatomic resemblance to a tooth.
