该层进行了评估，通过扫描电子显微镜和测量的水力传导率之前和之后2分钟的局部处理氯化钾，中性草酸钾，半中和草酸或中性和酸性草酸盐。然后在酸挑战前后对处理过的玷污层进行显微镜和功能性重新评价。用KCl处理的层在微观上或功能上都没有改变，并且容易受到酸蚀刻的影响。 用草酸盐溶液处理的牙本质表面变得不那么渗透，并且耐酸。
The layer was evaluated by scanning electron microscopy and by measurement of hydraulic conductance before and after 2-min topical treatment with potassium chloride, neutral potassium oxalate, half-neutralized oxalic acid or both neutral and acidic oxalates. The treated smear layers were then re-evaluated microscopically and functionally both before and after acid challenge. The layers treated with KCl was not altered either microscopically or functionally and were susceptible to acid etching. Dentine surfaces treated with either oxalate solutions became less permeable and were acid-resistant.
