    So, what’d you find out?
    I’m watching with interest, as it has seemed to me that I’ve been getting too much apical bleeding when I took a final trip to the apex with .50w as I was taught.
    Regards,

    Paul, at present with endo and the erbium there is no safe wattage to go to the apex with , all will cause the PDL to bleed in my experience.

    I stay at present 2-3 mm away and accept that the apex may not be sterile. ANother way is to use a diode in there for the final 2mm.

    Hope that helps…..rushing off to work

    Paul,

    The change in protocol from what you were taught is now 1.5W, 34/24 air/water Z-2 fiber, 4mm from apex, with at least 7 passes UP the canal to have complete sterilization. We have found that the energy levels of the 200um tip pass about 3-4mm beyond the tip, so no longer is it neccessary to go to the apex the final pass at .50W .

    Email me if you have any more questions….we will be augmenting the procedures as we see more research come in I am sure, but this is the latest model that shows complete sterilization (98.6%) in the canals, and NOT going to the apex, as the apex is affected by the energy used at 1.5W.
