@Dr. Sanket Pandey: Yes, cured Calcium Hydroxide materials are not helpful. Keep in mind the BC liner is not a Ca(OH)2 material. It’s a bioactive resin. This is why you need the pure bioceramic to interact with the cells before placing the BC Liner on top of it. Dycal is a good material except that it’s not as biocompatible and it does wash out over time. When you go back in time you see the Dycal is gone. But if that’s all you have to work with it’s better than the alternatives. Cheers!
