    Dr. Wascom, below is a link to Activa’s website which explains bioactive better than I can!

    You said activa flowable is bioactive, what does that mean

    (Why does it not bond to the adjacent tooth?)
    It does bond to the adjacent tooth. The bond is to a smooth small surface. It breaks cleanly away with a torque of a spatula. The tooth is restored in a neutral position. The contact is a direct build against the adjacent tooth. No unpredictable aggressive wedging is needed.

    Still I have a problem with being sure the floor of the deep box preps is not sealed w/o glass ionomer.)

    Activa is bioactive just like a glass ionomer.

    1- Diagnodent 12 or less reading within 1.5 mm of the prep border
    12 to 24 reading on intermediate dentin
    24 to 36 on deep dentin
    2- Activa is not a typical composite. The filler and the resin are one in the same. Flowability has nothing to do with how highly filled it is.
    3- I do use Clean and Boost. It is very acidic and it cleans up any residual oils. I admit etching enamel can only help and not hinder a bond.
    4- Activa is a dual cure. Follow up with additional light curing is not necessary. However, I could be wrong and additional light curing may provide a further cure.

    I always learn something from your clinical tips. You are good. It is generous of you to share. Comments on this tip:
    1-It is interesting that Diagnodent can be used that way but I wish you said what readings indicate remaining dentin decay versus no decay.
    2-Sorry, but flowable is flowable…not nearly as filled as paste. I am surprised you believe the marketing hype about its being suitable for occlusal forces over time. I believe they would say it, but I don’t believe they are serious.
    3- Surprised to see you not acid etch the enamel (because self etch resin doesn’t etch enamel as well as phosphoric acid and gives inferior bond by comparison), and
    4- Lastly, surprised that you did not hit the filled restoration with the curing light from buccal and lingual after the band was removed.
