My only issue is that I am finding with some canals my GP points do not go to length right away and sometimes, even with extra instrumentation, I struggle. Sometimes 1mm short and others 2mm short. I am wondering if this is a result of cutting efficiency of KontrolFlex? Should I always finish with an EndoSequence file? All files and GP points are Brasseler. I am using BC points with BC sealer. I always check for apical patency as well.
Thanks for your time!
I'm sorry for the delay. Your post fell through the cracks. But you have a very good question that comes up quick often. The issue of cones not being an exact fit for some preparation is not uncommon. This happens to me to clinically. This is partially due to the heat treated files and the ever so slight unwinding that makes the file thinner than the perfect taper and partially due to the fact that dentin has a modulus of elasticity and can ever so slightly bounce back. Furthermore, cones can distort and sometimes the coating can be too thick on individual cones. Either way, the solution is simple. Rather than doing too much more instrumentation, as long as you feel the canal is clean and you have no more tissue left on the walls (clean dentinal shavings and paper points,) then you can drop down in size with the cones. In tight maxillary or mandibular molars I may commonly instrument a MB canal to a size 30 or 35/04 and then fit a size 25 or 30 BC Cones respectively. The key is to make sure to have have enough sealer in the canal to fill in the gaps. Higher flow sealer may also be helpful in that it can allow escape of the sealer around the cone during cementation so the cone does not hang up high. You can use either BC Sealer or BC Sealer HiFlow for that purpose. I've recently been enjoying the higher radioopacity obtained by the BC HiFlow but BC Sealer is good as well.
