I have the unique opportunity to try many files that come on the market. One of the previous files I used was the Protaper Gold and Vortex Blue. I thought they are very good files and still is but Edge Endo has put out a file that I think is better. Clinically to me, it's more flexible, stronger, and a fraction of the cost. It's called Edge Evolve. The EdgeEvolve™ Heat Treated is available in tip sizes 17, 20, 25, 30, 35, 40 and Taper sizes 04, 06, 08, 10 for each tip size with a maximum flute diameter of 1.0 mm for each file. This is one case that I performed on tooth #15 using .04 taper in one visit. One thing I don't really like is that the file seems to "click" while working very similar to the Brassler Sequence files. My favorite file so far is still the EdgeEndo X7.
