Higher intakes of flavonoids are associated with lower salivary IL‐1β and maintenance of periodontal health 3–4 years after scaling and root planing
Bibliographic record
Abstract
AIMS: Higher intakes of fruits and vegetables, and vitamin C are associated with improved periodontal healing post-scaling and root planing (SRP). This study determined if this association was sustained at 3-4 years post-SRP, and if flavonoid intake is associated with periodontal health. Whether reduced probing depth (PD) is sustained and whether PD is correlated with salivary IL-1β, IL-6 and CRP at 3-4 years post-SRP were also studied. MATERIALS AND METHODS: Clinical periodontal outcomes, dietary intakes and salivary markers of inflammation were measured in patients (n = 43, 23 females, 37-93 years) who had undergone SRP 3-4 years earlier and had been part of a periodontal maintenance programme. RESULTS: Flavonoid intake was inversely associated with PD (p = .042) and salivary IL-1β concentration (p = .015) after adjustment for multiple confounders. When changes in PD were considered, the association of flavonoid intake with reduced PD became borderline significant (p = .051) but persisted for IL-1β (p = .018). PD at 3-4 years and 2-4 months post-SRP was similar. There was a positive correlation between PD and salivary IL-1β (p = .005) but not with salivary CRP and IL-6. CONCLUSION: Higher flavonoid intake is associated with lower IL-1β. Also, regular supportive periodontal therapy maintained the improved PD at 3-4 years post-SRP regardless of smoking status.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
