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

Table 5

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

Age group	Parameter	n	Half	Median	Rho	value
18–36	HPL	246	1.52	1.30	0.27	0.001
	SMT	246	3.10	2.75
37–48	HPL	251	2.03	2.00	0.28	0.001
	SMT	251	2.97	2.70
49–59	HPL	253	2.06	1.80	0.45	0.001
