Aim: The purpose of this study was to compare the working length in primary teeth using intraoral digital radiovisiography and two apex locators for accuracy.
Materials and methods: This is an in vivo study done in 30 primary teeth which are indicated for pulpectomy in children aged 5–9 years. All the teeth selected for the study had adequate remaining tooth structure for rubber dam isolation and radiographically visible canals. During the pulpectomy procedure, the working length was determined by digital radiovisiography and apex locator. The teeth were divided into three groups: group I—radiovisiography, group II—apex locator-I (Root ZX mini), and group III—apex locator-II (i-ROOT). The measurements were then compared for accuracy.
Results: There is no significant difference in the mean root length measurements from the three techniques.
Conclusion: The study concludes that electronic method for determining the working length of root canal was found to be more accurate than the radiographic method.
Clinical significance: The clinical correlation can be interpreted from the fact that the more the machine can work in extreme environments the more accurate it is, and the better it is for the dental professionals.
