Although pathogenic bacteria have been the main causative factor in periodontal disease, host response accounts for the majority of periodontal destruction by releasing various inflammatory mediators, which has a negative impact on the periodontium. The host immune responses are regulated by various classes of T-cell subsets. Initially, periodontal disease can be explained with the T-helper 1/T-helper 2 paradigm. However, the discrepancies associated with it have led to the discovery of T-helper 17, which is responsible for the secretion of the cytokine interleukin-17 (IL-17). IL-17 is mainly a proinflammatory cytokine associated with periodontal inflammation, but controversies still exist with regard to whether they have a protective or destructive role in periodontal disease. Thus, the emergence of IL-17 has opened a new perspective of periodontal disease pathogenesis, but more number of researches is needed in this field to consider IL-17 as a predictable biomarker for periodontal disease.
