Mucosal thickening, stratified according to lesions associated with periodontitis (furcation lesions and vertical infrabony pockets)

Variable	Furcation lesions	Vertical infrabony pockets
n	43	51
Minimum (mm)	0	0.5
Maximum (mm)	5.5*	19.0*
Mean ± SE	2.48 ± 0.26†	5.25 ± 0.46†
Prevalence of mucosal thickening (%)	69.8‡	90.2‡

n, number of sinuses; SE, standard error.

^*Statistically significant intergroup differences in maximal (mm) mucosal thickening, P < 0.001.

^†Statistically significant intergroup differences in prevalence of mucosal thickening, P < 0.001.

^‡Statistically significant intergroup differences in mean (mm) mucosal thickening, P < 0.001.
