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

Table 4

Correlation between the length and the height of the periapical lesions adjacent to the maxillary sinus and the thickness of Schneider’s membrane, according to sex.

Sex	Parameter	n	Half	Median	Rho	value
Female	HPL	567	1.72	1.40	0.38	0.001
	SMT	567	2.60	2.00
Male	HPL	409	2.12	2.00	0.32	0.001
	SMT	409	3.59	3.10

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