title: Temperature change in the pulp chamber during complete crown preparation.
abstract: This study observed the temperature changes in the pulp chamber during tooth preparation for a complete crown. Twelve extracted, morphologically intact human teeth were chosen: four canines, four premolars, and four molars. Six teeth, two of each, were cooled during preparation with an air-water spray; the remaining six were air-cooled. Minimal reduction of dentin using an air-water spray coolant resulted in a lowered temperature in the pulp chamber, mainly with the cross-grooved TDA diamond stones. The application of an air coolant resulted in a temperature rise in the pulp chamber.
