    Dr. McLaren. Your photography of tooth sections and natural anatomy is unmatched. Understanding the exquisite micro-anatomy of tooth structure can help in esthetic reconstruction as well as design of margins for adhesive cementation. The analysis of enamel rod orientation to bonding and cementation is well known. What are your thoughts on the direction of dentin and margin cementation? Illustrations of hybrid layer adhesion in the literature are almost always in perpendicular orientation with dentin collagen fiber direction. What are the implications of parallel or undercut dentin orientation at the margins on long term adhesive strength and stability?

    • Ed McLaren says:

      Great Question: to be honest I don’t know the answer— But since cologen is fibrous and flexible unlike Enamel cutting obliquely and or parellel to the dentin tubeles will probably not have the effect like micro-fractures in enamel if the rods are undercut.

      A great research project for someone.
