Introduction: Bacterial challenge in periodontal diseases activates both local and systemic immune responses of a macroorganism by increasing multiple proinflammatory factors that can be discovered in gingival crevicular fluid (GCF) and in saliva. We tested the hypothesis that IL-1β concentration in GCF and saliva correlates with periodontal health and diseases. Materials and methods: The study included 62 people (mean age 36±14 yrs), divided into three groups - patients with periodontitis (24 people), patients with gingivitis (19 people) and periodontally healthy people (19 people). Saliva and GCF samples were taken from all participants and the levels of IL-1β in all samples were determined by ELISA.
Results: IL-1β concentrations in GCF of healthy individuals were significantly lower than the IL-1β concentration in GCF of patients with gingivitis (p=0.009) and with periodontitis (p.

: Oral biomarkers have gained attention as non-invasive tools for assessing systemic diseases due to their potential to reflect physiological and pathological conditions. This review aims to explore the role of oral biomarkers in diagnosing and monitoring systemic diseases, emphasizing their diagnostic relevance and predictive capabilities in clinical practice. : This narrative review synthesizes the current literature on biochemical, immunological, genetic, and microbiological oral biomarkers, with a focus on their sources, types, and clinical applications.

Periodontitis, a widespread inflammatory disease, is the major cause of tooth loss in adults. While mechanical periodontal therapy benefits the periodontal disease treatment, adjunctive periodontal therapy is also necessary. Topically applied anti-inflammatory agents have gained considerable attention in periodontitis therapy.

The purpose of this study was to determine the levels of IL-17, Bcl-3 and IκBζ gene expression in the gingival crevicular fluid (GCF) of psoriatic and healthy individuals and to compare the clinical periodontal parameters in the patient and control groups. A total of 10 psoriasis patients and 2 healthy patients in the control group were included in the analysis for IL-17, Bcl-3, and IκBζ gene expression in the GCF. Periodontal health, gingival index, plaque index, and mobility (using a periotest device) levels were compared between the groups.

: This study aimed to evaluate the role of A-PRF (advanced platelet-rich fibrin) in the enhancement of wound healing and protecting the periodontal health of mandibular second molars after the extraction of mandibular third molars. Additionally, the study assessed the levels of pro-inflammatory cytokines in the gingival crevicular fluid (GCF) of mandibular second molars as markers of inflammation. : Twenty-five systemically healthy adult patients with bilateral removal of impacted mandibular third molars were included.

Changes in the positions of teeth occur during orthodontic treatment due to the application of forces that cause restructuring of the periodontal tissue. In the last decade, substantial research has been conducted to detect different biomarkers in the gingival crevicular fluid (GCF) to obtain a better assessment of the periodontal status. The purpose of this review is to describe how the levels of certain biomarkers from the gingival fluid change during tissue remodeling throughout orthodontic treatment.
