The effect of fast turning burrs and diamond points upon teeth during cavity preparation was tested in a model experiment under laboratory conditions, in order to establish possible damaging effects upon the pulp through an increase in temperature. The most effective protection comes from water cooling. Also successful was the technique of intermittent instead of continuous preparation. Only methods currently used in practice were tested thus making the test particularly valuable to daily practice. Thus it could be proved that the use of super-torque airotors as well as of the micromotor cannot cause thermic damage to the pulp if used circumspectively.
在实验室条件下的模型实验中，测试了快速旋转的牙钻和金刚石车针在窝洞预备过程中对牙齿的影响，以确定温度升高是否可能对牙髓造成损害。最有效的保护措施来自水冷。间歇性而非连续性预备技术也取得了成功。仅测试了目前在实践中使用的方法，因此该测试对日常实践特别有价值。由此可以证明，如果谨慎使用，超扭矩气动牙钻和微型电机的使用不会对牙髓造成热损伤。
