GIANT COMPLEX ODONTOMA OF THE MANDIBLE: A CASE REPORT AND LITERATURE REVIEW

Nedim Kasami, Vladimir Popovski

Abstract

Odontomas constitute a developmental defect of hard dental tissues and are classified as benign odontogenic tumours. They are composed of all dental structures and tissues: enamel, dentin, cementum and pulp. As regards histomorphological features, two types of odontomas have been differentiated: complex and compound. Odontomas represent from 4.7% to 76% of odontogenic tumours. Their aetiology has not been fully understood. Injury, infection and genetic factors are often named among the causes. Odontomas are considered a type of odontogenic hamartoma, and are generally reported not to exceed 3 cm in diameter. As hamartomas, giant odontomas generally show no signs or symptoms, and are usually detected by chance in radiographic images taken in relation to disrupted eruption or mislocation of teeth, or if they perforate the mucosa to become exposed in the oral cavity. To present the case study of an erupting complex odontoma on the left side of the mandible in an 11-year-old girl. The analysis covered medical documentation of the patient, diagnostic casts, orthopantomographs and description of operative protocol. The case study has been complemented with the review of up-to-date literature. A lesion composed of osteoid tissue was removed during one-day surgery without subsequent augmentation with a bone substitute material. There were no post-surgery complications. A follow-up orthopantomograph taken 2 months and 2 years later showed that the wound had been healing correctly. Odontomas are benign lesions that can be removed during one-day surgery without the absolute need for augmentation with xenogenic or allogenic material.
