INTRODUCTION: Working length determination is a crucial step for success of pulpectomy. Various new modalities have been developed. The newest technology includes EAL. Electronic apex locators require less chair side time, do not produce pain and avoid unnecessary radiation which makes it more superior in paediatric endodontic procedures. AIM: To evaluate and compare Root ZX mini apex locator and Radiovisiography (RVG) for determining working length in primary molars. MATERIALS AND METHODS: A sample of 30 primary molar teeth was subjected to working length determination by Root ZX mini and RVG. The data was collected and then tabulated and subjected to statistical analysis. RESULTS: On comparison among two groups, it was found there was no difference between the efficiency of modalities. A positive correlation was seen among Root ZX mini and RVG (ICC = 0.99). CONCLUSION: Root ZX mini and radiovisiography are seen to be precise in determination of working length in primary molars. It can be said that Root ZX mini i. e the electronic apex locators can be used as an adjunct to Radiovisiography and conventional radiography.
