Repairing Composite Margin Erosion Caused by Diet Soda- By Thomas W. Mitchell, DDS, FAGD

Introduction: 

This is one of my Diet Coke drinkers who's eroded the facial enamel away from 2 year old composites on 8 and 9. Now the composites look like islands. Instead of replacing them the plan is to polish them so they're flat with the enamel, then refurbish the margins with a combination of Interface Ceramic Dentin and Enamel Primer, Surpass Universal Adhesive and Titan Flowable Composite.

After 2 years of 6-7 Diet Cokes/day the composites look like islands as the enamel erodes away.

First thing I did was to flatten the surfaces by polishing with a disc.

I isolated each one with Teflon tape and etched and cleaned with Clean and Boost. This is #8.

I painted on Interface, let it dwell for 10 secs and then dried. Then a couple coats of Surpass 2, dried that and coated the surface with Surpass 3 plus a little Titan Flowable Composite over the margins. (Interface ceramic dentin/enamel primer penetrates the marginal defect really well and is immediately converted when Surpass 2 is added creating a very strong bond).

Then I repeated the procedure for #9.

Conclusion: 

The procedure is Clean and Boost for a few seconds to clean and etch the surface. Then on the clean and dry surface let Interface dwell for 10 secs and dry that. Add a couple of coats of Surpass 2 and dry, then a coat of Surpass 3 (and when the margin is really deteriorated I include a little Titan Flowable Composite). Now we can get a few more years out of these composites, assuming he really does cut out the Diet Coke (good luck with that!).
