Abstract

The effect of pulpal pressure on the shear bond strength of Scotchbond and Gluma was evaluated in the presence and absence of smear layers. There was no statistically significant difference in bond strength for either Scotchbond or Gluma on dentin with a smear layer in the presence or absence of 32 cm of hydrostatic pulpal pressure. When no pulpal pressure was present and the smear layer was removed, the bond strength of Scotchbond fell while that of Gluma nearly doubled. When 32 cm of pulp pressure was applied, the bond strength of Scotchbond/Silux fell 86% and that of Gluma fell 75% in 24 hours.
