Could Pine Tree Roots Help Filling Retention?

As dentists, we’re always looking for a way to improve what we do.  Now comes word from the University of Illinois at Chicago that perhaps an extract from pine tree bark could help decrease sensitivity and actually increase longevity of bonding restorations.
Since dentistry moved to predominantly composite filling materials, dentistry has become dependent on the chemistry of the bonding process to ensure quality and long lasting fillings.  The problem has always been that a great bond can be created between enamel and the materials, but a weaker bond exists between the materials and the dentin, which lies under the enamel.  
Researchers applied extracts of root bark from Chinese Red Pine.  Among other things, they discovered "the dentin was changed so that it was more compatible with resin fillings when they were applied to a tooth, binding to them more tightly”.
Obviously, more studies need to be done on this, but I’m guardedly optimistic about the potential for this.  I’m anxious for more science to be done.
