The treatment modalities for periapical lesions include non-surgical root canal treatment, periapical surgery, or tooth extraction. If non-surgical treatment is deemed ineffective or difficult, periapical surgery is the treatment of choice.

What causes periapical lesion?

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.
