摘要：

Periodontitis or Periodontal disease(PD)and Rheumatoid arthritis(RA)are two the most common chronic inflammatory diseases.Periodontitis is a biofilm associated destructive inflammatory disease of the periodontium caused by specific microorganisms.Rheumatoid arthritis is an autoimmune condition and is identified by elevated serum autoantibody titre directed against citrullinated peptides or rheumatoid factor.Periodontitis may involve some elements of autoimmunity.Recent studies have established that PD and RA show a common pathway and could be closely associated through a common dysregulation and dysfunction in inflammatory mechanism.The enzyme peptidyl arginine deiminase(PAD),expressed by Porphyromonas gingivalis(P.gingivalis)is responsible for the enzymatic deimination of arginine residuals to citrulline resulting in protein citrullination and its increased accumulation in RA.Citrullination by PAD may act as a putative biologic link between PD and RA.Association of Human leukocytic antigen-DR4 antigen has been established both with RA and PD.Several interleukins and inflammatory mediators(ILs)and Nuclear factor kappa beta ligand are linked to these common chronic inflammatory diseases.Antibodies directed against heat shock protein(hsp 70 ab)of P.gingivalis,P.melanogenicus and P.intermedia are raised in PD as well as RA.Both the conditions share many pathological and immunological similarities.Bacterial infection,genetic susceptibility,altered immune reaction and inflammatory mediators considered responsible for RA are also associated with PD.So it is plausible that a biological link may exist between PD and RA.Therapies aimed at modifying the expression and effect of inflammatory mediators and effector molecules such as matrix metalloproteinases,proinflammatory cytokines and autoantibodies of structural proteins may probably reduce the severity of both RA and PD.
