I was in a course last weekend, given by a Prosthodontist, self-proclaimed non-Bondodontist. He showed a slide of #3 with endo, and large alloy had been removed from access. This tooth had easily 4-5mm of axial wall height, with at leat 2mm thick walls from surface to interior of pulp chamber. The slide showed heavy brown sclerotic, decay-free dentin within the floor of the prep. He stated he would definitely use a post, and asked who wouldn't use a post here. I said I'd placed a bonded core b/c there was so much good dentin at the walls, and I basically hate placing posts in molars, and he wasn't sure that would be a great long-term idea due to lack of good bond strength to sclertoic dentin.

What are the studies showing for sclerotic dentin bond strengths using Simplicity/ Anchor? This has been bugging me for a week.

Both Surpass and Simplicity bond well to this type of dentin. Of course, the bond strength will be something less than normal dentin but it will be very effective if you do as instructed.

thanks jk - I have prepared teeth after placing Anchor on this type of tooth, and clinically the results seem stellar. Of course long-term the verdict is still out, but I feel more comfortable with bonding these cores in than placing posts in rarely-straight roots.

Thanks for getting back so quickly - have a great weekend.

Heck, if you can't pull the stuff off right away, you usually can't get it off later.

Cool
