Periapical granuloma

Periapical granuloma (also known as a dental granuloma) is a type of inflammation that occurs in the dental pulp of a tooth. It is a common consequence of untreated dental caries and is often associated with toothache and tooth loss.

Causes

Periapical granulomas are caused by bacteria that invade the dental pulp as a result of dental caries, dental trauma, or other factors. The bacteria cause an inflammatory response in the pulp, leading to the formation of a granuloma.

Symptoms

The symptoms of a periapical granuloma can vary, but often include toothache, sensitivity to hot and cold, and swelling of the gums around the affected tooth. In some cases, a periapical granuloma can lead to the formation of a dental abscess.

Diagnosis

Diagnosis of a periapical granuloma is typically made through a combination of clinical examination and dental X-rays. The X-rays can show the presence of a radiolucent area at the apex of the root of the affected tooth, which is indicative of a granuloma.

Treatment

Treatment of a periapical granuloma typically involves root canal therapy, in which the infected pulp is removed and the root canal is cleaned and sealed. In some cases, surgical removal of the granuloma may be necessary.

Prognosis

With appropriate treatment, the prognosis for a periapical granuloma is generally good. However, if left untreated, it can lead to serious complications, including tooth loss and the spread of infection to other parts of the body.
