Odontomas are nonaggressive, hamartomatous developmental malformations composed of mature tooth substances and may be compound or complex depending on the extent of morphodifferentiation or on their resemblance to normal teeth. Among them, complex odontomas are relatively rare tumors. They are usually asymptomatic in nature. Occasionally, these tumors become large, causing bone expansion follow...

Calcifying cystic odontogenic tumor (CCOT) previously known as calcifying odontogenic cyst (COC) is a relatively rare lesion. It was first reported as a separate pathologic entity by Gorlin et al in 1962 as a likely analog of the cutaneous calcifying epithelioma of Malherbe or pilomatricoma. Because of the diverse clinicohistologic features and the various neoplastic potential, there have been ...

Odontomas are odontogenic benign tumors composed of dental tissue. Majority of these lesions are asymptomatic and are often detected on routine radiographs. They can be thought of as "tooth hamartomas" with the lesion consisting of various tooth components. They are divided histologically into complex odontomas and compound odontomas. This paper describes the case of a compound odontoma in a 13...
