Problems solved by technology

However, there is currently no endodontic cavity glue composite material that can be directly used for 3D printing
[0004] At present, it is still very difficult to uniformly disperse the filling additives and functional additives in the pulp cavity glue material and realize its functionalization, and there are few related reports. At present, the relevant research on the preparation of 3D printing pulp cavity glue composite materials rarely
