Odontoma

Definition:
Odontoma is a benign tumor that usually forms at the root of a tooth. It may have genetic origins or may result from some sort of trauma to the tooth.
It  is a hamartoma of odontogenic origin.The average age of people found with an odontoma is 14, and the condition is frequently associated with an unerupted tooth…..CLICK & SEE THE PICTURES

There are two types: compound and complex.

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 Odontoma 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 2011; 66% of odontogenic tumors are odontomas (University of Louisville School of Dentistry). 22% of odontogenic tumors are odontomas.

In July of 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 17 year old Ashik Gavai. This odontoma is proposed as “The World Record” to date.

Symptoms:

The most common symptoms are:Pain,Rash,Diarrea,Headache,Back pain,Constipation,Fever,Caugh,Runing nose,Vision change.

The list of signs and symptoms mentioned in various sources for Odontoma includes the 6 symptoms listed below:

*Dysphagia ( Dysphagia is difficulty in swallowing.There are about 194 causes of Dysphagia, including diseases and drug side effect causes.)
*Lump on gums
*Delayed tooth eruption (It is a condition in which there is a slow or late development of a tooth. There are about  60 causes of Delayed tooth eruption)
*Absent tooth
*Delayed primary tooth loss
*Increased bone size under tooth

Causes:
There are several causes of odontoma, some of them are :

*Dental conditions(Any condition that affects dental organs such as the teeth and gums. Examples of dental conditions include tooth decay, tooth infection, gingivitis, periodontitis, impacted tooth and canker sores)

*Oral conditions(Any condition affecting the mouth. Mouth conditions can affect any structure of the mouth such as teeth, gums, lips, tongue and cheeks. Conditions that can affect the mouth include candidiasis, oral cancer, stuttering, cleft palate, bad breath and gingivitis. )

*Head conditions(Any condition affecting the head. Some head conditions can be serious such as cancers and skull fractures whereas other conditions may be less threatening such as headaches and head lice)

*Benign tumors (A benign tumor is one that does not spread or “metastasize” to other parts of the body; a “malignant tumor” is one that does. A benign tumor is caused by cell overgrowth, and thus is different from a cyst or an abcess,)

Diagnosis:
Odontoma does not usually show external symptoms. These tumors are revealed when the x-rays are examined by the dentist. Although it is true that a delayed tooth or absent tooth may suggest there is a need for further examination.

The presence of an a tumor of dental origin requires further examination to determine what type of tumor it is before further action is taken. In addition, a histological diagnosis of the tissues that were extracted provides valuable information to the dentist.

No one really knows why an odontoma forms. The most likely reasons are trauma and/or infection at the site. Some dentists and researchers believe they are hereditary or they develop because of genetic mutations. One example of an inherited syndrome is known as Gardener Syndrome. It is responsible for a wide range of tumors in the body, including occasional odontoma.  When examined at the cellular level, all of the dental tissues are found, but in an abnormal combination.

Pulp, dentin, enamel and cementum may sometimes resemble a tooth like structure in a compound odontoma. These denticles are found in a surrounding supporting layer of fibrous cells. Since it is decalcified, the enamel looks like spaces around the tiny tooth structures.   Looking closer, you can see the calicified material either as a solid mass or as multiple, small tooth-like bodies visible by x-rays. Because it is easily separated from its bony location it can be distinguished from other possible tumors.

A complex odontoma has no specific sequence for all of the dental tissue. It does not resemble normal tooth structure. At the cellular level it appears as mostly tubular dentin that encloses hollow spaces. These circular spaces are decalcified but they once held enamel. On the edges there may be a thin layer of cementum which forms a capsule like tissue surrounding the mass.

Treatment :
The only real treatment of an these dental tumors is removal by surgery. An early discovery and treatment will be beneficial to the patient. It is a benign tumor made of dental tissue and it is a fairly simple extraction in most cases. A speedy recovery is generally expected.  Some complex tumors can result in complications after extraction. So it is essential to stay in contact with the dental surgeon.
