Changes in Maxillary Sinus Mucosal Thickening following the Extraction of Teeth with Advanced Periodontal Disease: A Retrospective Study Using Cone-Beam Computed Tomography

Table 3

Measurements of MT by CBCT on the tooth extraction side and the nonextraction side before and after tooth extraction.

Variables	Baseline	Follow-up	value
Tooth extraction side ()
SL (mm)	25.90 (20.98 -31.55)	13.05 (0-18.38)	<0.001
ST (mm)	7.55 (3.18-9.95)	1.70 (0-2.43)	<0.001
MT, (%)	35 (97.2%)	14 (38.9%)	<0.001
Nonextraction side ()
SL (mm)	18.15 (0-22.70)	19.00 (0-23.75)	0.142
ST (mm)	2.55 (0-5.98)	2.50 (0–7.03)	0.232
MT, (%)	14 (58.3%)	14 (58.3%)	1

SL: the length of the sinus mucosal thickening; ST: the thickness of the sinus mucosal thickening. Statistically significant differences () were determined using the Wilcoxon test.
