Cemento-Osseous Dysplasia-Like Lesion and Complex Odontoma Associated with an Impacted Third Molar

Abstract

We present a case of a 36-year-old female with a benign fibro-osseous lesion consistent with cementoosseous dysplasia (COD) that was located coronally to the crown of an impacted mandibular third molar tooth and was associated with a complex odontoma. The pathogenesis of this unusual association is discussed and the odontogenic origin of COD is suggested.

Odontoma associated with mandibular transmigrated canine in a geriatric patient: Second case report

“…10 Infrequently, the aggregation of an odontoma and transmigrated canine has led to the impaction of additional adjacent teeth, including a premolar or lateral incisor. 14,15 Prodromidis et al 16 2 with biopsy-proved dentigerous cyst formation. 22,23 It is advised that oral cystic-appearing tissue undergo histopathologic assessment for diagnosis and rule out a malignant process.…”

“…Prodromidis et al 16 reported focal COD proximate to a complex odontoma and impacted third molar, questioning whether this was a causal or casual relationship. Similarly, Borghesi et al 17 recorded a case of focal COD; compound odontoma; peripheral osteoma; and cemento‐ossifying fibroma; attributing their concurrence to chance, hormonal imbalance or genetic process.…”

Management of Large Erupting Complex Odontoma in Maxilla

“…Compound odontomas may appear as tooth like structures containing enamel, dentine, cementum, and pulp and may be single or multiple [ 4 ]. Complex odontomas appear as a disorganized amorphous mass of calcified hard tissues [ 4 , 5 ]. Both lesions usually present in the first two decades of life [ 4 ].…”
