Eruption of Odontomas into the Oral Cavity: A Report of 2 Cases

Abstract

Odontomas are the commonest odontogenic tumors of the oral cavity and are by nature asymptomatic. They consist mainly of dental tissue that may or may not be arranged in an orderly fashion. Their presence is often detected accidentally or due to the presence of a dental disturbance such as an unerupted tooth. The very rarity of odontomas erupting into the oral cavity validates the need for more current literature on the phenomenon. Our report of two cases aims to present and discuss the rare event of an erupting odontoma with the dental community.

The Unique Case of Rapid Developing Compound Odontomes Following Fibrous Tissue Removal Around Impacted Tooth

“…[12] Eruption of odontoma is rare but mostly observed with complex odontomas and in between age 12 to 59 years old. [13] The slow-growing odontomas are hardly ever exceeded the size of a tooth, but when the odontomas become bigger which are occasionally about up to 6 mm and more in diameter, these lesions can result in cortical bone expansion. [1] Bony expansion is seldomly associated with compound odontomas but frequently related to complex odontomas.…”

Surgical Removal of Complex Odontoma – Case Report

“…[1] Paul Broca in 1867 coined the term odontoma , referring to tumors formed by the overgrowth of transient or complete dental tissues. [2], [3] Through usage they are considered to be hamartomatous malformation rather than true neoplasm. [4] The World Health Organization, in 2005 categorized odontomas as calcified irregular mass not resembling teeth, as complex odontome and calcified mass bearing resemblance to the teeth, as compound odontome.…”

An Erupted Compound Composite Odontoma Associated with Supernumerary Tooth

“…The average age of people found with an odontoma is 14 years [1]. The condition is frequently associated with one or more unerupted teeth [2]. Though most cases are found impacted within the jaw, there are instances where odontomas have erupted into the oral cavity [2].…”
