Glad you’re still posting here ,Glenn , we’ve all benefitted by your posts.
I’ve done the same thing only w/ waterlase and diode combo. The last couple times though, I’ve defocused the waterlase , stopped as much oozing as it would and then used Ultradents Astringident with a small brush tip in the sulcus and gotten good results-guess I just didn’t want to get up , setup and reposition the diode (being a little lazy I guess). Hopefully, when my office remodeling is done next week, it won’t be as big a deal.

Hey Glen
I kept wondering where the heck you found all the time to do the posts you were doing.

To put useful stuff on, takes a lot of time. You could always resort to the one liners that fill up half of DT 🙂

How can it be that water pooling is causing the Waterlase to stall.

I thought the water was accelerated , could it be that the laser energy doesnt travel well through the pooled water and that is why it stops cutting.

(PS my tongue is firmly entrenched in my cheek……and by the way the newest biolase adds for bone and endo dont mention hydrokinetics……..are the rambles of an insane man making a difference?)

I dont have the Biolase but there is a fine line between to much water……..pooling , and too little which leads to charring.

Many times in narrow preps you will find under the scope that there is charring and stalling, the water actually doesnt get down beside the tooth to cool and rehydrate it.

I think your post is an excellent one Graeme and the water/air combo is something that is very important in working without anesthetic. To little cause pain , to much slows it down ( the water).

Great stuff guys………..

Glenn

Yep
My observation is that once the air flow stops moving the water (deep narrow cavity) the pooled water absorbs the energy of the pulse and nothing happens on the tooth. Increasing the air flow rate clears the water and allows a mist to enter the cavity rather than a puddle of water. The surface needs to be wet, not drowned and buried.

I am sure the same happens with your laser too:-)))

Nice case Glenn and thanks for continuing to post here. I’m tired of Dental Town also and prefer to come here to learn from other dental professionals that are convinced of the benefits of dental laser usage.

The one thing I can say about Schalter’s forum is that so far we have no personal attacks. Dentists come here to learn, present new uses for lasers and also present clinical failures when they occur.

Here, if you have a negative comment because you had a bad day with the laser, someone chimes in and suggests a way to alleviate the problem. This is done in a professional manner.

Personally, I’m weary of the endless fighting, arguing and personal attacks on Dental Town.

Graeme,
Sometimes, the software needs to be recalibrated. You might call the service tech. I have not had that happen to me, but, if the unit gets out of calibration, sometimes this is the way it reacts. Mine, skipped pulses for awhile, had it recalibrated, and it works great. Hope this helps!

Wow, that’s a new one on me!

Although I don’t use nitrous, this is important info. Please keep us posted if you get a definitive answer.
