AimInterleukin-1 (IL-1) and prostaglandin E-2 (PGE(2)) are key inflammatory mediators involved in periodontitis. The purpose was to compare their salivary concentrations in relation to periodontal status and their changes after periodontal treatment, to determine their use as non-invasive diagnostic tools. Materials and MethodsIn this study, 74 subjects grouped in periodontally healthy, mild, moderate and severe periodontitis, according to clinical attachment level (CAL) and probing pocket depth (PPD) served as participants. IL-1 and PGE(2) were determined in unstimulated whole saliva by enzyme-linked-immunosorbent assay (ELISA). ResultsInterleukin -1 increased with the severity of periodontitis with a large effect size in prediction of CAL ((2)=0.35, p=0.0001). PGE(2) showed an increment in mild periodontitis and another in moderate. A significant effect size was also found between PGE(2) and PPD ((2)=0.12, p=0.003). Both mediators decreased after periodontal treatment. With a selected threshold of 212pg/ml, salivary IL1- predicted periodontitis with 78% sensitivity and 100% specificity. With a selected threshold of 121pg/ml, salivary PGE(2) predicted periodontitis with 78% sensitivity and 91% specificity. ConclusionThe high sensitivity and specificity of salivary IL-1 and PGE(2) in identifying periodontitis suggest a potential use as biomarkers for diagnosis of periodontitis presence and severity.
