An unusual case of compound odontome associated with maxillary impacted central incisor

Odontomas are the most common type of odontogenic tumor occurring within the jaws and are frequently associated with the retained deciduous teeth interfering with the eruption of permanent teeth. Compound odontomas are usually diagnosed in the anterior portion of the jaws and resemble tooth-like structure. These are usually asymptomatic. Complex odontomas are normally diagnosed in the posterior part of the jaws and consist of a disorganized mass with no morphologic resemblance to a tooth. The present case report of a 16-year-old female is a typical case of compound odontoma in the maxillary anterior region associated with retained deciduous incisor, which also resulted in failure of eruption of the permanent maxillary right central incisor. An intraoral periapical radiograph revealed the presence of a radio-opaque tooth-like structure in the apical region of retained deciduous incisor and an impacted permanent right central incisor whose path of eruption was impeded by the structure. Treatment included the surgical removal of the lesion followed by orthodontic extrusion of the impacted incisor. Follow-up was done for one 1 year and no recurrence was seen.
