title: Comparative Evaluation of Electronic Apex Locators and Radiovisiography for Working Length Determination in Primary Teeth in vivo.
abstract: OBJECTIVE
  The aim of this study was to evaluate the effectiveness of two different varieties of electronic apex locators and radiovisiography (RVG) for working length determination in primary teeth.
  
  
  METHODS
  A total of 30 primary teeth indicated for pulpectomy in children aged 3 to 8 years were randomly selected and subjected to working length determination using two varieties of electronic apex locators and RVG separately. The data were then subjected to statistical analysis.
  
  
  RESULTS
  A very strong correlation between electronic measurement methods and RVG length was observed.
  
  
  CONCLUSIONS
  Radiovisiography and apex locators are equally effective in determining working length in primary teeth. How to cite this article: Abdullah A, Singh N, Rathore MS, Tandon S, Rajkumar B.
