Our impression is very positive, the teeth show excellent reproduction of the anatomical structures of the pulp cavity.
The consitency of the acrylic is good for manipulation of the root region, being adequate for simulation of the preparation of the root canals. It also called our attention the material used to simulate the pulp tissue (a kind of “powder” and not a wax as in other products of other manufacturers), which seemed to us very positive.
This pulp material does not interfere negatively in the preparation of the canals, is easily soluble and helps to simulate a “pulp bleed” when dissolved in the irrigating substance.
