title: [Measurements of the temperature during the use of dental ultrasonic devices].
abstract: This investigation worked at temperature measurements in cylindric pieces of copper for determination of surface temperatures and in root dentin of calves using ultrasonics by varying intensity, water flowing and pressure. In each experiment two different dental ultrasonic devices were used with two tips. The experiments with sufficient water flowing showed that the spray temperature which was determined separately in further experiments influenced the measurements mainly. On the other hand an insufficient water flowing resulted in remarkable findings showing for example temperatures in the pieces of copper higher than 195 degrees C and macroscopic changes on the root surface in form of carbonization and alterations of cementum and root dentin.
