Remaining ratio (%) in canals with an isthmus according to the root position in the AH Plus, EndoSeal MTA, and EndoSeal+PUI groups.

Location	AH Plus	EndoSeal MTA	EndoSeal MTA + PUI
Apical	7.46 (1.37-31.38)	45.14 (35.14-62.81)	30.13 (5.81-47.06)
Middle	8.41 (2.7-25.93)	22.94 (11.49-31.46)	3.19 (0.29-10.73)
Coronal	2.29 (0.79-8.32)	23.37 (15.08-32.06)	0.79 (0.14-5.86)
value	0.149	< 0.001	0.002
value [1]	1.000	0.003	0.057
value [2]	0.270	0.003	0.002
value [3]	0.278	1.000	0.772

The normality of the data distribution was tested using the Lilliefors test and the Shapiro-Wilk test. Variables are presented as median (interquartile range), and values were computed using the Kruskal-Wallis test due to the nonnormality of the variables. Post hoc analysis was performed using the Bonferroni correction, and the adjusted values are presented as below: value [1] computed between apical and middle. value [2] computed between apical and coronal. value [3] computed between middle and coronal. , , .
