Effect of subgingival instrumentation on neutrophil elastase and C-reactive protein in grade B and C periodontitis: exploratory analysis of a prospective cohort study

  • Background: Assessment of the effect of subgingival instrumentation (SI) on systemic inflammation in periodontitis grades B (BP) and C (CP). Methods: In this prospective cohort study, eight BP and 46 CP patients received SI. Data were collected prior to and 12 weeks after SI. Blood was sampled prior to, one day, 6, and 12 weeks after SI. Neutrophil elastase (NE), C-reactive protein (CRP), leukocyte count, lipopolysaccharide binding protein, interleukin 6 (IL-6) and IL-8 were assessed. Results: Both groups showed significant clinical improvement. NE was lower in BP than CP at baseline and 1 day after SI, while CRP was lower in BP than CP at baseline (p < 0.05). NE and CRP had a peak 1 day after SI (p < 0.05). Between-subjects effects due to CP (p = 0.042) and PISA (p = 0.005) occurred. Within-subjects NE change was confirmed and modulated by grade (p = 0.017), smoking (p = 0.029), number of teeth (p = 0.033), and PISA (p = 0.002). For CRP between-subjects effects due to BMI (p = 0.008) were seen. Within-subjects PISA modulated the change of CRP over time (p = 0.017). Conclusions: In untreated CP, NE and CRP were higher than in BP. SI results in better PPD and PISA reduction in BP than CP.
