As part of my quest for faster, simpler, better composites this is #29 DO - low C factor - done with Clean and Boost, Superb, Titan A2 Flowable, and bulk filled Exquisite, all cured with my Valo light set on high - 3200mW/cm2 - or "Plasma" setting. This is an ideal scenario for this procedure, and if I were more efficient it could have been done faster. Exquisite's great for this because it has very low shrinkage. My main concern was would I see the dreaded "white lines". I did not.
I'll keep trying these as I think it's a simple and quick procedure in these low C factor areas. I don't think we need to limit this technique to small preps, but I wouldn't recommend it if there's a cusp that's not well supported by dentin. I'm still looking for an explanation for the x-ray appearance of an open contact when it was tight, closed, with floss snapping thru.
