Table 2 MT in normal MT test groups (n = 8) and normal MT control groups (n = 4) and mean changes from pre-extraction to 6 months post-extraction (mm; mean ± SD)

From: Effect of ridge preservation at molar extraction sites with severe periodontitis on the Schneiderian membrane thickness changes: a pilot study

  Normal MT in test group Normal MT in control group P value
Pre-extraction 1.35 ± 0.83 1.54 ± 0.93 0.330
Post-extraction 1.15 ± 0.83 1.32 ± 0.86 0.256
Changes 0.20 ± 0.47 0.22 ± 0.66 0.355
P value 0.106 0.338  
  1. P value in the last row are intragroup P values comparing changes of mucosal thickness from pre-extraction to 6 months post-extraction by paired samples t test
  2. P value in the last column are intergroup P values by Student’s t test
  3. MT, mucosal thickness
