Indirect pulp treatment
OtherCarious dentine was sampled from the mesial portion of the cavity floor and the pulpal wall was entirely covered with one of the randomly selected materials: GIC containing 4.5% DOX; GIC containing 1.25% CHX or GIC as a control group. The antimicrobial concentrations were chosen based in the previous in vitro results obtained in this study. The cavities were then temporarily restored using a conventional GIC. Within 3 months after the initial treatment,the materials were carefully and completely removed, a new dentine sample was collected, and the teeth were then restored with a light-cured composite resin using a bonding system, after a new placement of the initial liner material.
