Table 4 Chi square test showing perforation rate by different morphologies
From: Crestal endoscopic approach for evaluating sinus membrane elevation technique
Morphology | No perforation | Perforation | P value |
|---|---|---|---|
No. (%) | No. (%) | ||
Flat (n = 4) | 4 (100) | 0 | X2 = 4.80 P (chi) = 0.09 |
Irregular (n = 4) | 2 (50.00) | 2 (50.00) | |
Polyp (n = 4) | 4 (100) | 0 |
