Very similar to the teeth used on the WREB Examination. Ready to mount in your ModuPro ONE typodont. The RTX teeth are fabricated with a hard enamel-like outer layer, a more soft yellow dentin-like inner layer, and a very soft red-colored pulp chamber. Artificial caries is then added to the MESIAL surface, in a location that requires critical thinking and competent operative skills. The caries is natural-looking in color and texture and gives a tugback feel with the explorer. In addition to the visible caries appearance, caries may be hidden along the DEJ with a dentin color, where the operator must use an explorer to determine the extent. A truly remarkable tooth.
