Paul – great questions! Generally, my protocol is 0.25W with no air and no water. Sometimes, I’ll use just a little air, depending on how sensitive the dentin is. I’ll apply the energy over the sensitive area from about 5mm away. I move in a small circular fashion slowly getting closer to the sensitive area. After 30 seconds, I test the area with whatever made it sensitive in the first place. I continue with this until the sensitivity is gone. I consider it successful if the symptoms don’t return.
So far, the patients that I have used the Erbuim on that had true dentinal hypersensitivity have not had symptoms recur. Of course, all contributing factors had also been addressed. I’ve only done it on about a dozen patients.
