To maximize enamel micro-retention and marginal seal without causing excessive dentin demineralization or post-operative sensitivity To completely remove the hybrid layer in dentin and expose collagen fibrils for chemical chelation To activate matrix metalloproteinases (MMPs) in the underlying deep dentin To sterilize the cavosurface margin against Streptococcus mutans penetration
