CRP and periodontal disorder: Periodontal inflammatory burden represents all sites that bleed on probing in addition to all other sites that are inflamed but do not bleed on probing, as it is known that cells within the connective tissue underlying the periodontal pockets may secrete inflammatory mediators such as CRP, plasminogen activator1 and fibrinogen,4 which in turn may lead to systemic problems.3 By using the web app Periodontalwound, the clinician can show the patient the extent of the wound and inflamed area, representing periodontal disease, in their oral cavity (Fig 1).
