What causes periapical pathology?

In contrast, the primary cause of periapical lesions is endodontic infection. PAMPs-triggered immune response induces proinflammatory cytokines and subsequent periapical pathosis, including chronic inflammation and bone destruction. The primary cause of periapical lesions does not overlap with metabolic disorders.

How is a periapical cyst treated?

Treatment. Periapical cysts are treated by enucleation and curettage, either through an extraction socket or via a periapical surgical approach when the tooth is restorable or the lesion is greater than 2 cm in diameter. If the tooth is to be preserved, endodontic treatment is necessary, if it has not been done.

Is a tooth infection bacterial or viral?

A dental abscess, or tooth abscess, is a buildup of pus that forms inside the teeth or gums. The abscess typically comes from a bacterial infection, often one that has accumulated in the soft pulp of the tooth.

While most are lined by epithelium derived from rests of Malassez, epithelial lining may be respiratory type derived from the maxillary sinus, in the setting of a periapical lesion communicating with the sinus wall Round to oval radiolucency, often with well defined cortical border (this border can be lost when infected)

What are the most common symptoms of periapical pathology?

CLINICAL PERIAPICAL TESTS 1. PERCUSSION- indicates inflammation of the peridontium. 2. PALPATION- determines how far the inflammatory process has extended periapically. 15. 3.

What kind of bone is affected by a periapical cyst?

Dependent on tooth affected, size of cyst / extent of bone destruction and accessibility for treatment Squamous cell carcinoma and epidermoid carcinoma may arise from the epithelial lining of periapical cysts Pathologic bone fracture (occurs with large cysts that erode nearly completely through the jaw)
