| Abstract | ||||
| Aim: The purpose of this study is to compare the accuracy of Root ZX II and SIROEndo in calculating the working length (WL) in primary teeth. Methods: Twenty primary molars teeth planned for extraction were used, after access cavity preparation the actual working length for each root canal was measured, All root canals were then measured by using both devices. Difference between the electronic and actual canal lengths were calculated. Results: At the accuracy limit ± 0.5 mm showed there was no significant difference between both devices; the Root ZX II device showed accuracy 76.66% % while the SIROEndo Pocket showed accuracy 71.66%, when the difference was ± 1 mm. there was also no significant difference, the results were shown to be 98.33% for the Root ZX II device and 96.66% for the SIROEndo Pocket (p < 0.05). Conclusion: Both electronic apex locators (EAL) devices can be used as a reliable tool in measuring working length in primary molar teeth. | ||||
