Consumption of bilberries controls gingival inflammation

Area of Science:

• Oral health research
• Nutritional science
• Inflammation studies

Background:

• Bioactive compounds in berries may mitigate oral disease risk.
• Gingivitis is characterized by gum inflammation and bleeding on probing (BOP).
• Cytokines in gingival crevicular fluid (GCF) are key inflammatory biomarkers.

Purpose of the Study:

• To evaluate bilberry consumption's effect on BOP in gingivitis patients.
• To assess bilberry's impact on GCF cytokine levels.
• To compare bilberry intervention with placebo and standard dental care.

Main Methods:

• Randomized controlled trial with placebo, bilberry (250g/500g daily), and standard care groups.
• Intervention duration was seven days.
• BOP measured clinically; cytokine levels (IL-1β, IL-6, VEGF) analyzed using Luminex MagPix in GCF.

Main Results:

• Bilberry consumption reduced BOP by 41% (250g) and 59% (500g), comparable to standard care (58%).
• Significant reduction in IL-1β, IL-6, and VEGF levels observed only in the 500g bilberry group.
• Placebo group showed a 31% BOP reduction.

Conclusions:

• Bilberry intake ameliorates gingival inflammation markers.
• Daily consumption of 500g bilberries significantly reduces key inflammatory cytokines in GCF.
• Dietary interventions with bilberries offer a comparable effect to standard care for gingivitis management.
