Periapical Lesions and Their Relationship to Schneider’s Membrane in Cone-Beam Computed Tomography

Table 6

Correlation between the height of the periapical lesions adjacent to the maxillary sinus and the thickness of the Schneider membrane, according to side.

Side	Parameter	n	Half	Median	Rho	value
Right	HPL	525	1.89	1.70	0.28	0.001
	SMT	525	3.18	2.70
Left	HPL	451	1.89	1.80	0.45	0.001
	SMT	451	2.81	2.20

HPL, height of periapical lesions; SMT, Schneider membrane thickness; Rho, Spearman correlation coefficient; value <0.010.
