Gargantuan infected complex odontome of the maxilla: A case report and a brief review

Odontomas are the most common benign tumours of odontogenic origin and are characterised by their slow growth and non aggressive behaviour. Odontomas are classified as complex, when the calcified dental tissues are simply present as an irregular mass bearing no morphologic similarity even to rudimentary teeth, or compound, if there is superficial anatomic similarity to even rudimentary teeth. A few odontomas have a mixture of compound and complex elements that consist of miniature well formed teeth associated with disorganised sheets of tooth structures. An event of huge odontoma intruding the maxillary sinus, emerging into the oral cavity because of expansive growth, illustrating both complex and compound elements is unusual. We describe such a treated case of an infected large complex odontoma, in which the lesion has breached the alveolar bone and oral mucosa in the area of the right maxillary molars in a 16-year-old male.
