Odontomas are most common benign odontogenic tumors, and have been defined as "mixed odontogenic tumor composed of epithelial and mesenchymal cells". Many authors are considered to be malformations rather than neoplasm. The etiology of odontoma is uncertain but hypothesized to involve local trauma, infection, inheritance or mutant gene interference with genetic control of tooth development. The recent classification by WHO divides odontoma into 2 groups such as complex odontoma and compound odontoma. Odontomas are usually asymptomatic and are usually discovered on routin dental radiographs. The most frequently encountered symptoms are impacted tooth and swelling. Radiographically, it appears as an irregular mass of calcified material surrounded by a radiolucent band. The possibility of an ameloblastic odontoma must be kept in mind during the differential diagnosis. Surgical excision and histopathological examination of the lesions is recommended. Following removal of the odontoma closing the incision and allowing the tooth to erupt spontaneously was considered. Hitchin suggested that spontaneous eruption may not occur if the root of the impacted tooth is completed. Failure to erupt would require a 2nd surgical exposure to place an orthodontic attachment. This report presents the result in treating patients, whose chief complaint was delayed eruption of teeth due to odontoma.
