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.

A provisional diagnosis of odontome was given.

Compound Odontoma

Odontomas are further sub-classified based compouhd their gross and radiographic features into compound small tooth like structures or complex a conglomeration ovontoma dentin, enamel and cementum [ 1 ]. Can occur in any tooth bearing area Compound odontoma usually occurs in anterior maxilla Complex odontoma usually occurs in posterior mandible.

The structures in complex odontomas are mixed and disorganized. We present an interesting and a rare case of compound odontoma in the mandible of an adult patient.

The superior part of the mass protruding towards the superior border of the mandible. The histological examination confirmed the clinical and radiographic diagnosis of compound odontoma.

After hemostasis, the area was irrigated with saline and the mucoperiosteal flap was sutured back [Figure odontomw 7]. In this case, the permanent canine was not retrievable and therefore it was removed together with the compound odontoma in order to rehabilitate the patient with an implant-supported prosthesis. A Dictionary of Dentistry.

Compound Odontoma

The teeth were surgically exposed at a later date and brackets were bonded on to the teeth [Figure – 8] and [Figure – 9]. Odontomas are an abnormal mass of calcified dental tissue, usually representing a developmental abnormality.


According to the World Health Organization classification, odontoma is an odontogenic benign tumor of the young age [ 1 ]. More compuond or haphazard arrangement of pulpal tissues, enamel or dentin. Views Read Edit View history. co,pound

We report a rare fompound of complex odontoma of mandible in a young boy. Odontomas are slow-growing, asymptomatic neoplasms found in jaws.

Introduction According to the World Cmopound Organization classification, odontoma is an odontogenic benign tumor of the young age [ 1 ]. Hitchin has said that odontomas are inherited or developed as a result of genetic mutation [ 8 ]. Cohen DM, Bhattacharyya I. Compound odontoma is twice as common when compared to complex odontoma.

Please review our privacy policy. These lesions are often associated with impacted permanent teeth [ 1011 ].

Impaction has been defined as the prevention of the eruption of a tooth to the expected times into a normal functional position due to the presence of an obstacle or reasons of different nature [ 812 ].

Introduction Odontoma is a benign odontogenic tumor. Frequently associated with an unerupted tooth Usually detected on routine radiographs Most commonly located between roots of erupted teeth or impeding the eruption of tooth Well marginated from surrounding bone May have a thin radiolucent region surrounding opaque mass Radiopaque matrix same density as components of adjacent teeth Early stage odontoma may have little calcified matrix, expanding the radiographic differential diagnosis Can occur as a component of combined odontogenic tumor, most commonly Calcifying cystic odontogenic tumor CCOT Multiple odontomas may occur as a component of: Odontomas are considered to be developmental anomalies hamartomas rather than true neoplasms.


The unerupted permanent maxillary central incisor could be seen at the apical portion of the cystic cavity.

Pathology Outlines – Odontoma

Odontomas are generally small; however, they may occasionally grow large, resulting in bone expansion. Odontomas are relatively common, asymptomatic odontogenic lesions, rarely diagnosed before the second decade of life.

Many asymptomatic; discovered upon exploring potential causes of Asymmetric tooth eruption Malposition of erupted teeth Occasional devitalization of adjacent teeth Can become symptomatic due to local infection sinusitis, infected adjacent tooth, exposure of odontoma to oral environment, etc and can present with swelling and pain Size: In other projects Wikimedia Commons.

Complex odontoma of unusual size involving the maxillary sinus: On palpation the swelling was tender, hard in consistency, noncompressible, and nonreducible. The odontomas consisting of multiple denticles were surgically removed and microscopic examination showed a lot of crown-like structures in a very irregular form, some of which were fused to each other at their apical parts.

These tooth-like structures were surgically removed and subjected to histopathological examination.

Colour Atlas of Oral Disease: The aim dompound this case report is to describe a minimally invasive surgical procedure to remove a compound odontoma localized in the premaxilla area associated with an unerupted permanent maxillary canine.
