Figure 2. Changes in systemic health status after each treatment (baseline and after 12 weeks).
HbA1c, IL-1β, and endotoxin levels in the serum were analysed. P values were calculated by repeated-measures analysis of variance with use of the Bonferroni-Holm adjustment for multiple comparisons.
SRP: scaling and root planing, SRPAT: scaling and root planing with additional toothbrushing, CTR: control, HbA1c: haemoglobin A1c, IL-1β: interleukin-1 beta.
a)Significant difference from the control group (P<0.025).
