Limited success.
I’m going from memory here. But as I recall we did about six sessions each about 5000-6000J (100usec 6.0w, 20 Hz) I bathed the dorsum, lateral, and inferior aspects of his tongue where he could feel warmth.
After a couple sessions he described it as slight improvement of the ongoing burning tongue sensation, but not eradicated. After the other sessions, he said it really did not feel any different.
So, anyway, not really anything to write home about in this case.
He’s probably due for his regualr cleaning anytime in the next few weeks and I’ll follwup and let you know if anything has changed.
