COMPOUND ODONTOMA : A COMBINATION OF OPERATIVE AND ORTHODONTIC THERAPY

Background. Compound odontoma is an odontogenic tumor composed of epitelial and ectomesenchymal cells with a potential to generate a mass of irregular dentine and enamel tissue, forming a number of small, irregular, fibrous tissue connected growths containing enamel, dentine, cement or pulp tissue ; frequntly causing problems of permanent tooth eruption. Case report.a 9-year-old boy was presented for delayed eruption of the upper medial and lateral permanent incisors. X-ray showed an irregular bone mass shadow in the region of upper incisors, on additional analysis diagnosed as a compound odontogenic tumor. History data revaled a previous trauma that had caused avulsion of primary incisors. Treatment. The odontogenic tumor was removed by operative procedure under local anesthesia and referred for histology. Eruption of the permanent lateral incisor occured at 2 months and reached the occlusal plane at 3 months of the procedure. However, the medial permanent incisor showed absence of the eruption impulse, probably due to the completed root growth. In such a case, the operative-orthodontic treatment includes corticotomy and placement of a clasp upon the medial incisor crown. A specially designed orthodontic fixed aplliance enables the retained permanent medial incisor to pull out by force and reach occlusal plane. This case confirms one of the possible theories on the genesis of odontoma, with dental trauma as a significant and common cause, and illustrates the operative-orthodontic therapeutic option.
