Research on Chronic Periapical Periodontitis

Chronic periapical periodontitis, also known as chronic apical periodontitis (CAP), refers to the chronic inflammation of periapical tissues due to the long-term presence of infection and pathogenic irritants in the root canal, which is manifested by the formation of inflammation and destruction of alveolar bone. Periapical granuloma is the main type of CAP, in which apical granulation tissue is produced around the root tip of the tooth, limiting bacteria to the original infected area and activating the immune system in response to inflammatory stimuli. Notably, periapical granuloma is the early stage of CAP, and its inflammatory response is more intense than that of periapical cysts. Chronic periapical abscess is another clinical feature of CAP, which is limited to periapical region.

CAP is an inflammatory disease with microbial etiology. Various microorganisms from the dental pulp cavity play leading roles in the development of AP. Typically, bacterial lipopolysaccharide leads to AP by stimulating a local immune response. When enamel or cementum is opened because of caries or trauma, oral microorganisms may enter the pulp cavity or root canal system from the crown or dentin canal and directly contact the pulp tissue or alveolar bone. However, bacteria that cause CAP are usually less toxic than those causing acute AP. If not treated in time, the chewing efficiency of the teeth will be reduced and the toothache will become worse. It may also cause alveolar bone osteomyelitis or other diseases.

Most periapical infections are asymptomatic and the untreated inflammation usually develops gradually and is ongoing, referred to as chronic apical periodontitis. Chronic apical periodontitis refers to the chronic inflammation of periapical tissues caused by the long-term presence of infection and pathogenic irritants in the root canal, which is manifested by the formation of inflammation and destruction of alveolar bone. Uncontrolled infections often result in extensive bone loss around the root tip, which ultimately leads to tooth loss.
