  1. Grouping methods. N-G: commercial non-antibacterial adhesive + gentle adhesive displacement; N-H: commercial non-antibacterial adhesive + augmented pressure adhesive displacement; A-G: experimental antibacterial adhesive + gentle adhesive displacement; A-H: experimental antibacterial adhesive + augmented pressure adhesive displacement.
  2. Application method: Applied etching agent for 15 sec, rinsed for 15 sec and dried gently for 2 sec, leaving the acid-etched dentin moist. Applied adhesive for 10 sec and dried for 5 sec using 0.1 MPa air-blow for adhesive displacement in G groups or 0.3 MPa air-blow for adhesive displacement in H groups at the distance of 1 cm from the bonding surface. Adhesive application and air-blowing were repeated, followed by light-curing for 10 sec. Cavities were subsequently restored with Z250 resin composite and light-cured for 40 sec according to the manufacturer’s instructions.
