Table 3 MT in thickened MT test groups (n = 12) and thickened MT control groups (n = 7) 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

  Thickened MT in test group Thickened MT in control group P value
Pre-extraction 3.78 ± 2.36 4.63 ± 3.20 0.063
Post-extraction 1.58 ± 0.93 1.99 ± 1.54 0.329
Changes 2.20 ± 2.05 2.64 ± 2.70 0.289
P value  < 0.001*  < 0.001*  
  1. MT, mucosal thickness
  2. 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
  3. P value in the last column are intergroup P values by Student’s t test
  4. *Statistically significant difference (P < 0.05)
