Abstract Background Non ‐ surgical periodontal treatment (NSPT) is widely employed for the treatment of periodontal disease and yields significant clinical improvements. Gingival crevicular fluid (GCF) can be used to profile health and disease, and recent technological advances, such as multiplex bead immunoassays, are promising in identifying a wider array of GCF factors with the ultimate aim to predict the treatment response. Objective The aim of this systematic review was to compare the expression of GCF markers using multiplex bead immunoassays before treatment and during early, average, or late healing period, following non‐surgical periodontal treatment (NSPT). Methods An electronic literature search was conducted by two independent examiners (VK and NC) in MEDLINE, EMBASE, OpenGrey, LILACS, and Cochrane Library up to January 2020. The PICO question formulated was as follows: “In patients with periodontal disease, does the expression of gingival crevicular fluid (GCF) markers detected using multiplex bead immunoassay differ at baseline compared with early (≤30 days), average (6‐8 weeks), or late (≥3 months) healing after intervention?” Results A total of 366 publications were obtained and reviewed for eligibility for inclusion. Of these, 12 publications fulfilled the inclusion criteria and were included in the present review. Data for a total of 31 different GCF markers were extracted and summarized for early, average, or late healing after NSPT. Early healing following NSPT (≤ 30 days) indicated an increase in IL‐1β, TNFα, and IL‐10. At the average healing period (6‐8 weeks), IL‐1β, IL‐1α, IL‐6, TNF‐α, IFN‐γ, GM‐CSF, MCP‐1, and MIP‐1α were all reduced, compared to their respective baseline values. Three months after NSPT, IL‐1β, IL‐4, IL‐6, IL‐10, TNF‐α, and IFN‐γ were detected at reduced levels, compared to pre‐treatment levels. Overall, the changes following treatment indicated a reduction of inflammation present at baseline. Conclusion Following non‐surgical periodontal treatment, an upregulation of inflammation markers is noted early post‐operatively and a subsequent reduction of their levels three months following treatment. The investigation of levels of GCF markers associated with inflammation and regeneration, especially using multiplex bead immunoassay technologies, is a valuable tool to better understand the processes associated with healing following periodontal treatment.
