sorry but ...i have a question.
For those of you who have tried this experiment, when you dapped the Interface on the tooth was there any sensitive/stinky sensation from the patient?
If not, can we use this method and replace the protocol of using Sim 1 & 2 on freshly prepare crown prep and on the day of cementing crown (i.e. interface + Sim 2+cement)?

Thanks.
Gary

PS- can I participate on the experiment too? Me seventh Laughing

My experience is that the discomfort vanished immediately.

One certainly can apply the Interface/Sim2 combination at delivery, but it might be most effective done at time of prep.

What do you mean by a "stinky" sensation? Wuzzat? Question

I'm going to do some of these this morning.

Couple of questions:

1. Any comment for the patient as to anticipated longevity of desensitizing effect?

2. Any use in putting a sealer or flowable over the Sim 2 afterward?

Thanks

Durability is expected to vary. I would be hoping for 6 months but it is very dependent on a lot of factors. It usually goes longer than that but I prefer to be conservative.

Whatever is applied must be kept THIN so as not to be a periodontal liability.

patient today with a history of sensitivity on buccal #30, 31. 2mm recession on 30, 1mm on 31.

applied interface - no change
added sim 2, thinned, cured....no change
added thin layer of flowable on #30....slight change.

THis stuff works Exclamation
I have two patients back to back reported sensitive teeth.
Patient 1:
CC: CL V sensitivity on #3& 4. Previously repaired but getting more recession @ the gingiva .
Apply Interface generously and light air thin
Apply Sim 2 and air thin
Apply secondy Sim2 and full blow air thin for 3-5 sec.
Than cure.
Symptom immediately go away. Wow.

Patient 2:
Reported #17 PFM sensitive to bite and to cold/air.
Hx. over 6mos ago restored.
I wanna to ck her occlusion due to the fact that #17 is the only "molar" on the lower opposing full upper dentition. ( She is almost Type II endentulous) Anyway, I can not even begin to place the handpiece due to the air blowing through the tooth. So, I figure what the hack, lets give a try w/ Interface. Note: took several angle of digital bitewing and show no open margin on the crown.
So I did the same procedure as above except I just use the microbrush paint around the tooth and tying very hard to isolate the tooth w/out saliva or h20 in contact w/ the tooth.
I cured and test it w/ air.....sensitivity got a 80%improvement.
That is enough for me to go back and check her occlusion and sure enough she has cusp ridges pre-mature contacts. By the time I finished her prophy ( which was the initial reason she came) she reported the sensitivity and bite was gone.

Thank you Dr. Kanca Laughing

Another reason I like using the Interface is b/c it does not give the initial sensitivity or the stinggy feeling when you apply on the exposed dentin/ prep tooth surface. Unlike Sim 1 (if the patient is not numb or getting over the anesthesia) tends to have the initial sensitivity (cold/jumpy) feeling reported by my patients.
At least this is happening in my hands.

Question, Dr. kanca have you test its bond strength and compatibility of using Interface +Sim 2 for restorative bonding agnets? Will it work?

Were the surfaces cleaned at all prior to attempting a seal?

It yields the same bond strengths as regular Simplicity.

Cool

New (stupid) question.

Just saw a 14 yr old male, with sensitivity on M #28. This tooth has an incomplete enamel formation on the buccal that we have previously repaired, and no problems any where else on it. Today he displays pretty good sensitivity to flossing and contact with the side of an explorer.

Do you think it's possible to get the Interface to penetrate through the interproximal area for desensitization purposes, without resorting to removing tooth structure? Remember he's 14, and therefore not the world's greatest at hygiene....especially flossing. Confused

If there's a lot of plaque, it's going to be tough to get the desensitizer to the tooth surface. It would be most effective if the tooth surfaces are cleaned first. Then I would expect it would flow into the area. I have had success with this. Cool

John

I plan to wait a couple of weeks (hope he flosses as instructed), attempt to pack a cord (may anesthetize, too) and see how it goes.

Thanks for the answer

I am assuming that to use Interface with Surpass for sensitivity, one would skip bottles 1 & 2, just adding 3 after the Interface soaks in?
