In this study the influence of four different pretreatments showed significant differences on the permeability of cut dentin. On the average the application of 25% polyacrylic acid increased the permeability by approximately 10 percent, the application of 34% polyacrylic acid by 30 percent. The treatment with 0.1% chlorhexidin-digluconate produced no change of permeability. Calciumhydroxide suspension reduced the permeability by 15 percent and diminished the increase caused by phosphoric acid significantly.
