Erupted bilateral compound odontomas in a dog

A six-month-old, male Black Russian terrier dog was presented for oral masses on the distolingual aspect of the mandibular left and right first molar teeth. Intraoral dental radiographs showed periodontal support of the small teeth (denticles). Oral and radiographic examinations of the remaining teeth indicated no other dental abnormalities. The denticles had histomorphologic features of small teeth including normal appearing crown and root structures. Clinical and histopathologic examinations resulted in a diagnosis of bilateral compound odontomas with completely erupted denticles. Treatment consisted of extraction of all denticles and extensive curettage. The dog had uncomplicated wound healing with no signs of recurrence based on oral examination performed 15-months postoperatively.
