Aim: Investigate the accuracy of the Dual Move-Dual Pex (Micro-Mega, France) device in measuring the canal length when used with different heat-treated files and apical widths.

 
Materials and Method: Thirty-six single-rooted extracted teeth were included in the study. The actual canal length was determined under the microscope with #10 stainless steel under x2.5 magnification, by advancing the file until it was visible from the apical part. The teeth were modeled in alginate for electronic apex locator procedures. Without any preparation, 2 electronic working lengths were determined by using #10K with the apex locator, advancing up to 0.0 and 0.5 points. Firstly, electronic measurements were made at OneCurve 25,4%, 0.0 and 0.5 points, which is Micro-Mega's file. The same measurements were made with Endoart Action Gold-Action Blue Kit S1 file. After the instrumentation was completed, the same measurements were repeated with the F2 files of the sets. All electronic working lengths were compared among themselves and with the control group. Data were statistically analyzed using one-way Anova and Tukey tests. 
 
Results: When the measurements made with the static apex locator were compared with the control group, no significant difference was found both 0.0 and 0.5 points in the use of Endoart(p>0.05). 
There were significant differences between the static apex locator values ​​at 0.0 and 0.5 points in the measurements made during preparation in the use of Endoart. Values ​​read during preparation were higher. 
There were significant differences between the values ​​of the control group at 0.0 and 0.5 points in the measurements made during the preparation in the use of Endoart. Values ​​read during preparation were higher. 
No significant differences were found between the values ​​of the control group and the static apex locator values ​​at 0.0 and 0.5 points in the measurements made during preparation in the use of OneCurve.
 

 

Conclusion: It was found that simultaneous measurement and preparation using the Endoart  Gold-Blue Kit in the Dual Move-Dual Pex device tended to exceed the actual working length, while OneCurve did not tend to exceed. It would be useful to firstly determine the working length in static mode and then move on to the shaping phase. More beneficial results will be obtained when the device is used with its own files.
