Assessment of inflammatory cytokines in gingival crevicular fluid for diagnostic differentiation of apical periodontitis

Apical periodontitis (AP) is a chronic inflammatory condition resulting from microbial infection of the dental pulp. The host immune response and microbial interactions play a significant role in the disease's progression. Gingival crevicular fluid (GCF) provides a valuable, non-invasive source for detecting inflammatory biomarkers involved in AP, such as IL-1β, IL-10, and IL-23.
