Dry tooth structure in cavity preps for 5-10 seconds before applying Simplicity 1.

IGNORE anyone who disagrees or tries to argue otherwise.

no worries on dessication? I always thought that drying the tooth like that was some of the cause of dessication and sensitivity. I personally isolate the tooth. give it a blast of air for about 1-2 seconds and then use a cotton ball to dry it further.

Think of it this way- what if you wanted to coat the bottom of a bucket with paint and there was a layer of water there. You need to make room for the resin.

Desiccation AFTER placing Sim 1 would be BAD. But Sim 1 IS the hydrating element! This allows the Sim 2 to get even deeper into the dentin surface. The bond strengths jump.

Very Happy

Is this a new finding & advice. Seems I remember instructions said something like "dry don't dessicate".

No problem for me to dry it well before sim 1.

So why not just suction off the alcohol, can't get more dry than that; or would the alc leave an undesirable residue?

Thanks for the intructional post

Yeah, it did. After dwelling on this mentally and extensively during vacation I was running experiments yesterday and the initial bond values went way up when I did this- and it did every time I repeated it. Especially on deep dentin. This was a thinking response to the pulpal fluid thing as well as the water tree thing. We have to have the resin zone free of extraneous water when bonding takes place. Drying things like this means that pulpal fluid, whether you accept the premise or not, will be removed as a factor as it cannot flow out so fast as to catch up with this kind of drying. For the academicians, this should accomodate that effect. We may not be done with the topic yet.

Right- alcohol and acetone are chemicals too!

Thanks for the intructional post

Yes sir!

Very Happy Cool Exclamation[/quote] Blessed with early onset Altzheimers, my step by step for uncut enamel as in Maryland Bridge bonding is therefore: 1. Clean uncut enamel with alcohol; 2. Dry, Dry, Dry the alcohol with 5-10 seconds with syringe about 2 inches from prep; 3. Dab on Simplicity 1 on enamel and wings of temporary maryland bridge, wait 20 seconds; 4. Gently blow air about 2 sec from about 5 inches away to evenly disperse (not dry) the sim 1; 5. brush on the sim 2; 6. Gently blow excess sim2 about 2 seconds then light cure 20 seconds; 7. Place a brushful of sim2 on the enamel and the metal wings and do NOT cure 8. Place thin film of cement on wing of metal; 9. Press firmly to position; 10. Light cure multiple times from edges of metal (about 40 total for each wing)

Not here! New topic! Go her4:

I hate to be a pest about this but this is one of the things that messes up other forums- one topic morphing into another. For the purposes of being a good archive for all, it is best to keep topics and questions relevant to that already existent. Please feel free to begin another thread if it is appropriate. I will answer it! Cool

john, at what point is bond strength not an issue anymore - i mean at what point will you be completely satisfied? i understand the ramifications of higher bond strengths, but i always thought that 20 - 30 mpa was completely adequate, or is this "adequate" because this is just about the limit with todays agents?


take care,
d

Adequacy is a function of the stresses applied in a given situation. Everything fatigues over time and the higher one starts, the better. I am always in pursuit of the everlasting bond.

I do not think I will ever be satisfied- this is both a blessing and a curse.
