An odontoma (also termed odontome)[1][2] is a benign tumour[3] of odontogenic origin (i.e. linked to tooth development).[4] Specifically, it is a dental hamartoma, meaning that it is composed of normal dental tissue that has grown in an irregular way.
The average age of people found with an odontoma is 14.[5] The condition is frequently associated with one or more unerupted teeth. Though most cases are found impacted within the jaw there are instances where odontomas have erupted into the oral cavity. [6]
Classification
There are two main types: compound and complex.[7]
- A compound odontoma still has the three separate dental tissues (enamel, dentin and cementum), but may present a lobulated appearance where there is no definitive demarcation of separate tissues between the individual "toothlets" (or denticles). It usually appears in the anterior maxilla.
- The complex type is unrecognizable as dental tissues, usually presenting as a radioopaque area with varying densities. It usually appears in the posterior maxilla or in the mandible.
In addition to the above forms, the dilated odontoma is an infrequent developmental alteration that appears in any area of the dental arches and can affect deciduous, permanent and supernumerary teeth. Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The most extreme form of dens invaginatus is known as dilated odontoma.
Epidemiology
Odontomas are thought to be the second most frequent type of odontogenic tumor worldwide (after ameloblastoma), accounting for about 20% of all cases within this relatively uncommon tumor category which shows large geographic variations in incidence.[8]
Notable cases
In July 2014 in Mumbai, India, surgeons at Mumbai's JJ Hospital removed 232 tooth-like growths from a complex odontoma growing in the lower jaw of a 17-year-old boy. This is thought to be the largest ever number of such growths to be identified in a patient.[9]
Also in Mumbai an eight year old had 80 teeth growths removed.[10]
Another exceptional case of compound odontoma was reported in November 2014, involving the extraction of 202 teeth from a 7-year old girl in Gurgaon, India. "[11]
