Effect of PVA-AA on dentine bonding of HEMA.
PVA-AA, an esterification product of poly(vinyl alcohol) and acryloyl chloride, was synthesized and tested for its dentine bonding ability as an additive to 2-hydroxyethyl methacrylate (HEMA). The dentine bonding strength increased significantly by increasing the concentration of PVA-AA in HEMA. The dentine tensile bonding strength attained by the mixture of 10 wt% PVA-AA in HEMA is about 38% higher than that of HEMA or Gluma bonding agent. The dentine shear bonding strength also increased by increasing the acrylate content of the PVA-AA up to about 30%. Test results of cell culturing indicate that no toxic substance is released from PVA-AA to inhibit the cell growth.
