SHORT-TERM REACTION OF EXPOSED MONKEY PULP BENEATH ADHESIVE RESINS

Monkey pulpal responses to four adhesive resin systems used as direct pulp capping agents were histopathologically evaluated at 3, 7, 14, 30 , and 60 days after operation. No serious inflammatory reaction of the pulp, such as necrosis or abscess formation, was observed. Slight inf lammatory cell infiltration was the main inflammatory reaction of the exposed pulp, and the exposed area became occluded with dentin bridgin g as the observation period increased. Healing of exposed dental pulp beneath adhesive resin capping slightly differed depending on the mate rials used.
