Prevalence and Morphology of C-Shaped Canals: A CBCT Analysis in a Korean Population

Table 4

Distribution of configuration types in separated versus fused roots on panoramic radiographs of teeth with C-shaped canal on CBCT.

Configuration type	Separated roots, (%)	Fused roots, (%)
C1	62 (25.6)	279 (38.2)
C2	56 (23.1)	153 (20.9)
C3a	65 (26.9)	121 (16.6)
C3b	59 (24.4)	178 (24.4)
Total	242	731
value	0.863	<0.001

Data were expressed as number and percentage. Distribution of sample ratios among each subgroups was analyzed using the chi-square test. Distribution of configuration types in fused roots was significantly different ( value < 0.001).
