Why it matters for dental

Long-term cohort data now show that some patients with pristine periodontium still develop rapid gingival inflammation under identical plaque challenge, giving clinicians a measurable way to predict risk and intensify preventive protocols before attachment loss begins.

Key points

  • 25-year follow-up of 113 adults originally free of periodontitis; 18 % were classified 'high responders' to experimental gingivitis despite identical plaque levels.
  • High-responder status at baseline predicted 2.7-fold higher odds of future periodontitis progression over 25 years (p<0.01).
  • No difference in plaque index or bleeding on probing scores between groups at day 21 of experimental gingivitis, but high responders showed earlier IL-1β and IL-6 spikes.
  • Authors propose a simple 21-day experimental gingivitis test in young adults to stratify prevention intensity, especially in high-caries or ortho populations.
