My thesis is about conserving a Columbian Mammoth.  One of the
issues I encountered was a very fragile tooth.  After various
experiments, I decided on using a silane cross-linker known as
methyltrimethoxysilane (MTMS). This tight silane polymer has a very
low viscosity that reacts to the tooth's cell walls and to each
other allowing a ridged bond to occur.  By immersing or topically
applying 100% MTMS, it stabilizes and strengthens without causing
further delaminating and crumbling the tooth.  Also, MTMS is
compatible with other solvent based polymers, such as Acryloid
(Paraloid) B-72.  If you would like a copy of my thesis, please let
me know.
