I just bought the Apex NRG and have had pretty good success establishing an accurate working length. I have previously used the Justwo and the Root ZX. I had middling success with both of those. I do so much endo that it is worth my while to have reliable a apex locator.
Has anybody used an electronic apex locator that provided consistently accurate readings? In wet canals with sodium hypochlorite or blood? I would like to be able to insert the file to estimated working length and take a reading at the beginning of the procedure, before the pulpectomy has been completed. Are any of you able to do that? I would be willing to purchase another apex locator if it worked any better than these. It would be worth it to me.
