Comparative Evaluation of Accuracy of Different Apex Locators: Propex IQ, Raypex 6, Root ZX, and Apex ID with CBCT and Periapical Radiograph—In Vitro Study

Table 3

One-way ANOVA for comparison of the WL values measured obtained using the different techniques. df = 9, F value = 1.53. The actual WL value was closest to the value obtained with CBCT (), followed by Propex IQ (). However, the actual WL value was significantly different from that obtained with conventional radiographs ().

Multiple comparisons (LSD) (post hoc test)		value
Actual WL	Raypex 6	0.28
	Propex IQ	0.80
	Root ZX	0.23
	Apex ID	0.31
	Conventional radiographs	0.01
	CBCT radiographs	0.90
