Dr. Jurg Tschopp created the word "inflammasome" in 2002. Inflammasome activation and its function in disease processes have been the subject of significant investigation over the last 15 years. Four important inflammasomes have been identified: NLRP1, NLRP3, NLRC4, and AIM2. When these inflammasomes are activated, they process and secrete inflammatory cytokines such as IL-1b and IL-18, as well as cause pyroptosis, an inflammatory form of cell death. In this review, we will look at how these inflammasomes have been connected to Periodontitis pathogenesis.
