This in vitro study evaluated the effects of two dentin adhesive systems on dentin permeability. The XR‐Bonding System modifies the smear layer but does not open dentinal tubules. The Kanca or “total‐etch” technique (phosphoric acid, Tenure A and B, Scotchbond 2 Adhesive) removes the smear layer and opens dentinal tubules. Despite these differences, both systems reduced dentin permeability in a similar manner. XR‐Bond decreased permeability to 52% of the smear layer value, while total etching reduced permeability to 66% of that value.
