Advocates of this theory claim that since no technique can completely remove the smear layer from the coronal or radicular portion of the tooth because of the complex geometry of many cavities and the difficulty of obtaining adequate success, so it is better to alter the smear layer using agents like potassium oxalate, 5% ferric oxalate, 4% titanium tetrafluoride and certain bonding rd agents like 3 generation adhesives and self etching primers.
