Table 4 Changes in the detection rates of septa according to the height of septa in the maxillary sinus on panoramic radiographs in 61 patients

From: The significance of cone beam computed tomography for the visualization of anatomical variations and lesions in the maxillary sinus for patients hoping to have dental implant-supported maxillary restorations in a private dental office in Japan

Height of septa in maxillary sinus on CBCT Detection rate of panoramic radiographs (Frequency)
0 < <=1 mm 0% (0/1)
1 < <=2 mm 29% (2/7)
2 < <=3 mm 30% (7/23)
3 < <=4 mm 38% (5/13)
4 < <=5 mm 47% (8/17)
5 < <=6 mm 55% (5/9)
6 < <=7 mm 50% (2/4)
7 < <=8 mm 66% (2/3)
8 < <=9 mm -
9 < <=10 mm 100% (1/1)
10 < mm 66% (2/3)
