Hi Dr. Nasseh,
I’m assuming BC Liner is a sort of RMGI type of material. Do you treat it more like a resin material and only rely on the glass ionomer self setting portion for reduced shrinkage? I ask because if you place bonding prior to using a glass ionomer like material, then you don’t get the glass ionomer chemical bond to dentin properties as you’ve placed bond over the dentin already. If isolation is not a problem, would you prefer using normal composite for transcrestal defects like from external resorptive lesions? And if the lesion is deep enough to stay sub sulcular, would you prefer to use BC putty to repair the lesion instead of using BC liner?
