Apical periodontitis

Apical periodontitis is a type of inflammation that occurs around the apex (or tip) of a tooth root. It is typically caused by bacterial infection and is often a consequence of untreated dental caries or tooth decay.

Causes

The primary cause of apical periodontitis is bacterial infection. This can occur as a result of untreated dental caries, tooth decay, or a failed root canal treatment. The bacteria can infiltrate the pulp of the tooth, leading to inflammation and infection at the root apex.

Symptoms

Symptoms of apical periodontitis can vary, but often include pain, sensitivity to heat or cold, and swelling or tenderness in the gums around the affected tooth. In some cases, a dental abscess may form.

Diagnosis

Diagnosis of apical periodontitis is typically made through a combination of clinical examination and dental radiographs. The radiographs can reveal changes in the bone around the tooth root, indicative of inflammation.

Treatment

Treatment for apical periodontitis typically involves addressing the underlying cause of the infection. This may involve root canal treatment, antibiotics, or in severe cases, extraction of the affected tooth.

Prognosis

With appropriate treatment, the prognosis for apical periodontitis is generally good. However, if left untreated, the condition can lead to more serious complications, including dental abscess or spread of the infection to other parts of the body.
