The most common source of pain after a root canal is the inflammation of tissues around the tooth’s root. This is “periradicular inflammation.” Depending on severity, it does take some time for such swelling to go down and the tissue to fully heal. A wide variety of events can inflame these tissues. Keywords: Periradicular, Molecular Mediators, Inflammation, Regeneration, Dental Important Note : All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Apical periodontitis (AP) is an inflammation and destruction of periradicular tissues. It occurs as a sequence of various insults to the dental pulp, including infection, physical and iatrogenic trauma, following endodontic treatment, the damaging effects of root canal filling materials. Inflammatory mediators of periradicular lesions are poorly understood.

Periradicular inflammation

Periapical periodontitis or apical periodontitis (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. Inflammation of the periradicular site due to bacteria could cause recovery to deteriorate and induce periradicular infection. Careful evaluation of root canal filling material is required to optimise healing after the procedure. Periradicular, periapical or apical periodontitis can be defined as inflammation of all the supporting structures of the teeth in the area surrounding the apex of the tooth.

Chronic inflammation, However acute peri - apical periodontitis frequently presents as an acute flare of the periapical granuloma, while the periradicular abscess may occasionally demonstrate an acute flare on histopathology. Periapical granulomas are categorized on histology into EARLY, The results indicate that uninfected devitalized pulp tissues did not continuously release inflammatory mediators and cause persistent periradicular inflammation over a period of one year.

Acute periradicular inflammation in turn usually gives rise to signs and/or symptoms, including pain and swelling. The acute (symptomatic) process may develop without previous chronic inflammation or may be the result of exacerbation of a previously chronic asymptomatic lesion. Periradicular granulomas represent a subsequent reparative process of chronic local inflammation ( Gao .

Nonetheless, in all cases where viable bacteria remain in the root canal system there is a constant risk that they may perpetuate periradicular inflammation. In most cases, failure of endodontic treatment is a result of microorganisms persisting in the apical portion … A periradicular lesion evoked by bacterial infection consists of periapical inflammation with destruction of the periodontal ligament and resorption of the alveolar bone and root ( ).
