Eur J Med Res

August 2024

Department of Research Analytics, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai, 600 077, India.

Background: Activation of the IL-33/ST2 axis leads to the production of proinflammatory cytokines and thus to the triggering of osteoclastogenesis, which is why it plays an important role in the immunopathogenesis of periodontitis. The aim of this study was to compare IL-33 levels in serum, plasma, saliva and gingival crevicular fluid (GCF) of subjects with chronic periodontitis (CP) in comparison with the control group (CG).

Methods: This systematic review and meta-analysis followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was registered in the Open Science Framework (OSF): https://doi.

Increased of IL-18 levels are associated with periodontitis: a systematic review and meta-analysis.

BMC Oral Health

August 2024

Department of Research Analytics, Saveetha Institute of Medical and Technical Sciences, Saveetha Dental College and Hospitals, Saveetha University, Chennai, 600 077, India.

Article Synopsis
  • A polymicrobial dysbiotic film triggers an immune response in periodontal tissues, leading to increased IL-18 production, which then heightens inflammatory cytokines, worsening chronic periodontitis.
  • A systematic review and meta-analysis following PRISMA guidelines examined IL-18 expression across various biological samples from individuals with chronic periodontitis, analyzing data from multiple databases.
  • The results showed significantly higher IL-18 levels in the serum, saliva, and gingival crevicular fluid (GCF) of chronic periodontitis patients compared to healthy individuals, suggesting the potential of IL-18 as a valuable diagnostic marker.

A 65-year-old Caucasian male was referred to an endodontic specialist practice in a private clinic in December 2019 for the management of an asymptomatic, radiolucent lesion located at the cervical level of the distal root of his right lower first molar, noticed during a routine periapical radiograph. After an accurate evaluation with cone-beam computed tomography (CBCT), the subgingival lesion was diagnosed as a supracrestal external cervical resorption (ECR), with a circumferential spread ⩽90°, confined to dentine without pulp involvement. The lesion was treated with the following sequence: (1) a full flap accessed the ECR, (2) the granulomatous tissue was removed from the root area, (3) the cavity was refreshed and filled with a well-refined and polished resin composite, (4) the flap was sutured at the cemento-enamel junction.
