Effects of pH on the dentin surface.
A microleakage and scanning electron microscope (SEM) study was conducted in order to investigate the effects of acidic primers on prepared dentin surfaces. The microleakage study revealed that no significant differences were noted between the five materials tested in regard to leakage at enamel and dentin margins. SEM analyses revealed that the smear layers of all specimens were altered in some manner. Further long-term clinical studies should be conducted to evaluate acidic treatment of dentin.
