  • AbstractAimThe aim of this study was to assess the levels and diagnostic accuracy of a set of potential biomarkers of periodontal tissue metabolism in gingival crevicular fluid (GCF) from patients with chronic periodontitis (CP) and asymptomatic apical periodontitis ( AAP).Materials and MethodsThirty one GCF samples from 11 CP patients, 44 GCF samples from 38 AAP patients and 31 GCF samples from 13 healthy volunteers were obtained (N = 106). Matrix metalloproteinases (MMPs) ‐2 and ‐9 were determined by zymography; levels of MMP‐8 by ELISA and IFMA and MPO by ELISA. IL‐1, IL‐6, TNFα, DKK‐1, Osteonectin, Periostin, TRAP‐5 and OPG were determined by a multiplex quantitative panel. Statistical analysis was performed using linear mixed‐effects models.ResultsThe MMP‐9 and MMP‐8 were higher in CP, followed by AAP, versus healthy individuals (p < 0.05). ProMMP‐2, MPO, IL‐1, IL‐6, PTN, TRAP‐5 and OPG were significantly higher in CP when compared with AAP and healthy patients (p < 0.05). The highest diagnostic accuracies were observed for ProMMP‐2, ProMMP‐9, MMP‐8 and TRAP‐5 (AUC > 0.97) in CP, and for the active form of MMP‐9 and MMP‐8 (AUC > 0.90) in AAP.ConclusionGingival crevicular fluid composition is modified by CP and AAP. MMP‐9 and MMP‐8 show diagnostic potential for CP and AAP, whereas MMP‐2 and TRAP‐5 are useful only for CP.
