Intraoral dental sinus

Intraoral dental sinus (also known as a parulis) is a common dental condition characterized by the formation of a sinus tract in the oral cavity. This condition is typically associated with dental infections and abscesses, and is often a sign of underlying dental disease.

Etiology

The primary cause of an intraoral dental sinus is a dental infection. This can occur as a result of tooth decay, gum disease, or trauma to the tooth. The infection leads to the formation of an abscess, which can then drain through a sinus tract to the surface of the oral mucosa. This tract is the intraoral dental sinus.

Symptoms

Symptoms of an intraoral dental sinus can vary depending on the severity and location of the infection. Common symptoms include pain, swelling, and a discharge of pus from the sinus tract. In some cases, the patient may also experience bad breath or a bad taste in the mouth.

Diagnosis

Diagnosis of an intraoral dental sinus is typically made through a combination of clinical examination and dental radiographs. The dentist may also take a sample of the discharge for laboratory testing to identify the type of bacteria causing the infection.

Treatment

Treatment for an intraoral dental sinus typically involves addressing the underlying cause of the infection. This may involve root canal therapy, extraction of the affected tooth, or treatment of the gum disease. Antibiotics may also be prescribed to help control the infection.

Prognosis

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