[The prep-trainer--thermal control in the pulp space]

The "Prep-Trainer" was developed as teaching and checking aid in order to enable students and dentists interested in continued education to check themselves. The heat development in the pulp cavity is measured at the model. Measurements made by the author showed that the safest method for maintaining constant temperatures and thus avoiding over-heating of the pulp cavity is the cooling with the air-water spray handpiece by the dental assistant.
