EndoPrep® Upper and Lower Jaw (Opaque Crown, Transparent Root) is a dental training model designed for hands-on endodontic education. It consists of 28 teeth, with 14 in the upper jaw and 14 in the lower jaw.

The teeth feature opaque crowns and transparent roots, with the crown portion designed to be harder than the root portion. Each anatomically shaped tooth contains a pulp chamber and is suitable for practicing endodontic access cavity preparation and root canal filling procedures.

The teeth can be removed and replaced as needed. A nut-based mounting system beneath the upper and lower jaws allows the model to be attached to a dental phantom head for practical endodontic training.
