Table 1 Demographic and clinical parameters for all patients used in the analysis

From: Epigenetic regulation of inflammation in localized aggressive periodontitis

  Age Gender PD (mm) #PD > 6 mm CAL (mm) #CAL > 3 mm % affected sitesa % BoP % plaque
Severe LAP 13.70 ± 3.74 1M/9F 5.85 ± 0.9** 4.80 ± 2.4# 4.06 ± 1.24# 13 ± 10.49# 13.97 ± 8.54** 14.50 ± 9.54 45.60 ± 27
Moderate LAP 17.00 ± 2.21 5M/5F 5.38 ± 0.8** 1.60 ± 1.0 2.10 ± 0.45** 1.90 ± 1.14 8.30 ± 6.18** 14.20 ± 9.39 36.40 ± 17.85

  1. Means ± standard deviation. No statistical difference found between groups for gender, age, and BoP. Note: CAL value = 0 for healthy controls, as there is no attachment loss present in any site
  2. LAP localized aggressive periodontitis, HC healthy controls/mild gingivitis (< 25% BoP and no radiographic bone loss or attachment loss), PD mean pocket depth of affected sitesa (PD ≥ 5 mm with CAL ≥ 2 mm and radiographic bone loss), CAL mean clinical attachment level of affected sites, BoP bleeding on probing, NA not applicable as healthy controls did not present sites PD ≥ 5 with CAL ≥ 2 mm
  3. **p < 0.05 between LAP and HC; # p < 0.05 between severe vs moderate LAP and HC
