Abstract

Odontomas are the most common odontogenic hamartomas worldwide. Depending on the level of organisation of the tissues inside, these can be differentiated into compound type or complex type. As these are asymptomatic and do not cause any changes in the bone, they are often diagnosed during the routine dental examination. Complex odontomas are commonly found to occur in posterior mandible while compound odontomas are found in the anterior maxilla. A nine-year-old female child reported for a routine dental check-up, when a missing left permanent mandibular lateral incisor [32] was noticed. Further investigations revealed compound odontoma and unerupted 32, which is an unusual location. Early detection of these tumours is essential to avoid lengthy corrective treatments.

Highlights

Odontomas were first described by Paul Brocain in 1867
Complex odontoma has been known to have a slight predilection towards females, whereas compound odontoma is more common in males, contrary to previous reports that claimed there was no gender predilection [2, 4]
The present case report is of a compound odontoma in anterior mandible, associated with a retained primary tooth

Summary

Introduction

Odontomas were first described by Paul Brocain in 1867. He used the term odontoma for all odontogenic tumours; currently, the usage of the term has become much more restricted [1]. Odontomas are included in the WHO classification of head and neck tumours as a group of lesions affecting the odontogenic epithelium with odontogenic ectomesenchyme, with or without hard tissue formation [3]. These hamartomas have been described as either complex type or compound type. Intra-oral radiograph revealed multiple radio-opaque tooth-like structures close to the root apex of 72 and the presence of 32 (Figure 1). This led to the diagnosis of compound odontoma. Histopathological examination of the denticles was done, and compound odontoma was diagnosed
