Objective:
To assess the ability of salivary cytokine signatures to distinguish carious lesions from healthy oral states and gingival inflammation.
Approach:
- Study Design: A proof-of-concept case-control ancillary study using data from the ORASPORT cohort, analyzing 65 patients aged 18 to 30 years.
- Cytokine Analysis: Collected unstimulated whole saliva and quantified 9 cytokines using the S-PLEX Proinflammatory Panel 1.
- Assessment Methods: Evaluated assay sensitivity, linearity, reproducibility, and the ability of cytokine combinations to discriminate between groups.
Key Findings:
- All 9 cytokines were detectable in over 97% of samples; 8 were found in all patients.
- TNF-alpha was the strongest discriminator of carious lesions from healthy controls.
- IL-6 was elevated in patients with carious lesions compared to healthy controls.
- The combination of IL-17 and TNF-alpha provided the highest discrimination for carious lesions from healthy controls.
- The study found modest discrimination for carious lesions from gingival inflammation.
Interpretation:
IL-17 in combination with TNF-alpha and/or IL-1 beta are considered candidate salivary signatures for prospective validation.
Limitations:
- Modest sample size and narrow age range limited generalizability.
- Cross-sectional design prevented causal inference.
- Absence of radiographic examinations may have missed hidden lesions.
- Lack of periodontal probing limited characterization of gingival inflammation.
- Exclusion of patients with both caries and gingival inflammation reduced representation of overlapping conditions.
Conclusion:
The findings are hypothesis-generating and require validation in larger studies.
