“…There was only one compound odontoma in this study and it contained hyperattenuating tooth‐like material with areas suggestive of enamel. The radiographic characteristics of canine compound odontomas have been extensively described in multiple case reports and case series and mass associated tooth‐like material is a trademark Roentgen sign of these tumors . These masses are also often associated with impacted or unerupted teeth and mass‐associated cyst‐like structures have been described …”

Odontogenic neoplasms are locally invasive oral tumors in dogs. The purpose of this retrospective study was to describe CT characteristics for varying histopathologic types of canine odontogenic neoplasms. A boardcertified veterinary radiologist who was unaware of histologic findings reviewed and scored imaging studies. A total of 29 dogs were included in the study. Twenty-three of these dogs had concurrent dental radiographs. The most common CT characteristics for all tumor types were a direct association with or in the region of multiple teeth in 96.4% (27/28), contrast enhancement in 96.3% (26/27), alveolar bone lysis in 93.1% (27/29), and mass-associated tooth displacement in 85.2% (23/27). Mass-associated cyst-like structures were identified in 53.6% (15/28) and were only present in tumors containing odontogenic epithelium. Canine acanthomatous ameloblastomas (n = 15) appeared as extra-osseous (10/15) or intra-osseous (5/15) masses. Intra-osseous canine acanthomatous ameloblastomas were more likely to have mass-associated cyst-like structures and were subjectively more aggressive when compared with extra-osseous canine acanthomatous ameloblastomas. Amyloid-producing odontogenic tumors (n = 3) had subjectively uniform CT imaging characteristics and consisted of round soft tissue and mineral attenuating masses with multiple associated cyst-like structures. Fibromatous epulides of periodontal ligament origin (n = 4) were contrast enhancing extra-osseous masses that were rarely referred for CT examinations and 25% (1/4) were not visible with CT. Other odontogenic tumors were less represented or had more variable CT imaging characteristics. Mass-associated tooth destruction was appreciated more often with dental radiographs and extra-oral tumor extension was identified more often with CT.

“…Odontomas are slow-growing lesions that occur during odontogenesis, mainly in young dogs, resulting in dentition disruption and in prevention of eruption or displacement of normal teeth (Eickhoff andothers 2002, Gardner 2002).…”

A three-month-old, male German shepherd dog was admitted with a facial mass of two months' duration. Clinical examination showed a round mass, 3 cm in diameter, in the left infraorbital area. The upper last premolar deciduous tooth was not erupted. No other abnormalities were detected. Radiological examination revealed a posterior maxillary mass of mixed opacity. The mass was surgically excised. Histopathological examination demonstrated a connective tissue stroma containing foci of irregular enamel and dentine, resembling rudimentary teeth (denticles), surrounded by new bone formation. Morphology and structure of the denticles were also confirmed by scanning electron microscopy. A compound odontoma was diagnosed. One year after surgery, the dog was free of clinical signs.

“…In the case of odontomas, the tumour may consist of either multiple, small tooth-like structures (compound odontoma) or a conglomerate mass of odontogenic hard and soft tissue (complex odontoma) (Neville et al, 2002;Head et al, 2003). Odontomas have been diagnosed in mice (Ida-Yonemochi et al, 2002), dogs (Eickhoff et al, 2002;Felizzola et al, 2003;Papadimitriou et al, 2005), prairie dogs (Phalen et al, 2000), horses (DeBowes and Gaughan, 1998), cows (Tetens et al, 1995) and in an elephant (Raubenheimer et al, 1989). The so-called "odontogenic dysplasia in ageing rodents and lagomorphs" is defined as the disorganized development of the continuously erupting incisor teeth of rodents and lagomorphs, due to inflammation, trauma, toxicosis or age (Head et al, 2003).…”
