Local and Systemic Antimicrobials in Non-surgical Periodontal Therapy

The main treatment of every patient with periodontitis is non-surgical periodontal treatment (NSPT) with the ultimate goal to arrest inflammation. Given the biofilm microorganisms associated etiology of the periodontitis, NSPT can be combined with adjunctive antimicrobial therapy. Hence, this randomized clinical trial aims to compare the clinical and microbiological effectiveness and relative expression levels (REL) of proinflammatory cytokines tumor necrosis factor-alpha (TNF-α) and interleukin-17 (IL-17) between local and systemic antibiotics as adjunctive therapy to NSPT in patents with periodontitis stage 3.
