Odontoma is a benign odontogenic tumour, which is rather considered hamartoma. Hamartoma is not a true neoplasm, rather a growth of abnormal mixture of cells found in the body area they normally grows. Fully developed odontomas generally consist of enamel, dentin and pulpal tissues, in an unorganised manner. Some of them may contain cementum too. These are further grouped into compound and complex, depending on their clinical, radiographic and histologic features. Odontomas are generally asymptomatic and slow growing, but may cause bone expansion and hinderance in tooth eruption. These lesions are generally diagnosed by coincidence in radiograph. We are presenting a case and surgical management of complex odontoma and post-operative dehiscence in the anterior right maxillary region of a 38-year-old male.
