Cementoma
A benign odontogenic tumor
Cementoma[edit | edit source]
A cementoma is a type of benign tumor that originates from the cementum, a calcified tissue covering the roots of teeth. Cementomas are classified as odontogenic tumors, which means they are related to the formation and development of teeth. These tumors are generally non-cancerous and are often discovered incidentally during routine dental radiography.
Classification[edit | edit source]
Cementomas are part of a group of lesions known as cemento-osseous dysplasia. They are further classified into three main types:
- Periapical cemental dysplasia: This type typically occurs in the anterior mandible and is more common in middle-aged African American women. It is often asymptomatic and discovered on routine dental X-rays.
- Florid cemento-osseous dysplasia: This type affects multiple quadrants of the jaw and can be more extensive. It is also more common in middle-aged women of African descent.
- Cementoblastoma: This is a true neoplasm of cementum and is characterized by the formation of a mass of cementum attached to the root of a tooth. It can cause pain and swelling.
Clinical Features[edit | edit source]
Cementomas are usually asymptomatic and are often found during routine dental examinations. However, in some cases, they may cause symptoms such as:
- Toothache
- Swelling of the jaw
- Displacement of teeth
Diagnosis[edit | edit source]
The diagnosis of cementoma is primarily based on radiographic findings. On X-rays, cementomas appear as well-defined radiopaque masses that are often surrounded by a radiolucent halo. The appearance can vary depending on the stage of the lesion.
Treatment[edit | edit source]
In most cases, cementomas do not require treatment unless they cause symptoms or complications. When intervention is necessary, treatment options may include:
- Surgical removal of the lesion
- Endodontic treatment if the associated tooth is affected
Prognosis[edit | edit source]
The prognosis for individuals with cementoma is generally excellent, as these lesions are benign and do not transform into malignant tumors. Regular dental check-ups are recommended to monitor the condition.
