Application of root canal cleaning agents having dissolving abilities of collagen to the surface treatment for enhanced bonding of resin to dentin.
Commercial root canal cleaning agents with the ability to dissolve collagen were used for the surface treatment to enhance the bonding of dental resins. These agents increased the bond strength of a dental bonding agent to dentin. For example, the tensile bond strength to bovine dentin was 10.7 +/- 3.9MPa following the joint use of M and N and 8.8 +/- 2.2MPa following the combined use of P-S and N. In these cases, the damage to the tooth surface was very small and was equal to or less than damage caused by EDTA. These results demonstrate the usefulness of commercial root canal cleaning agents for dentin surface treatment due to their ability to enhance the bonding of dental resin.
