Tooth 15 was very calcified and patient was in pain. I used my "old school" profile series 29/04 taper to make sure I didn't loose my "Swagg." This was a cool case because it had 5 canals. I would love to try the Edge Endo file on one of these cases. By the way I still use Gates crown down 4, 3, 2.
